A NOTE FROM SAFWAN DOBASHI
Built for the moment between sets.
I'm Safwan Dobashi. I built Eccentryx for one job while standing in the gym between sets: open the next lift, log the set, and keep the data on your device.
Coming to the Bay Area. The next chapter is physical — a gym in the Bay Area, built around the same loop: train the set, log it, recover on purpose.
- Not another monthly program PDF.
- Not a social feed dressed up as training.
- Not a place to collect fake streaks while your lifts stall.
Eccentryx makes a narrower bet: a setup-built 7-day plan, local set logging, swaps, export, and erase controls — no wearable, no food log, no DNA, no 16-week runway.

YOUR FREE 7-DAY PLAN
Eight questions. A plan you can actually train today.
Free to use. Your answers shape the plan structure, exercise pool, time budget, recovery dose, substitutions, and priority work. Build the week, open Gym Mode, and keep the plan on your phone.
How trained are you right now?
Pick the level that matches your current consistency, not your best past phase.
What should the next 12 months optimize for?
Pick the outcome the plan should protect when tradeoffs appear.
What modalities do you want to schedule?
Select all training modes you want to combine. We will optimize recovery between them.
What needs extra priority?
Pick the areas that need more attention. Eccentryx should not assume one universal routine.
What equipment can you reliably use?
Pick what you can access most weeks, not what the perfect gym would have.
How long can most sessions actually be?
Pick the time budget you can repeat on a normal week.
Any area the plan should treat carefully?
Pick all that apply. This is training routing, not medical diagnosis.
What is your usual recovery base?
Pick your normal sleep range. This controls how aggressively the plan pushes.
What usually makes a plan fail?
Pick all that apply. These become the guardrails for your week.

Step 1 of 10
// 01 — THE WEDGE
The pattern we built against: months into a standard split, the bench stalls and a shoulder starts complaining.
Why 7 days, not 6?
Most templates force rest days because their structure can't sustain daily training — the off-days get labeled "recovery," and the stall that often follows gets ignored.
- The classical fix is wrong. Adding more rest days to a broken structure doesn't fix the structure — it just spaces out the breaking.
- Recovery is a verb, not a date. Eccentryx puts recovery inside every session, so today's effort doesn't become tomorrow's tax.
- The 3-phase session is the unlock. 10–20 min functional · 60–90 min lift · 15–25 min foam roll + targeted stretch — in that order, every day, no exceptions.
- Sustainability beats intensity. Most lifters can run an 8-week push. The harder part is making the next normal week clear enough to repeat.
- The result you can feel by week 4. You leave the gym restored, not wrecked. Day 2 stops feeling like Day 1's hangover.
What this gets you: 12 months of compounding progress instead of 8–10 weeks of intensity followed by 6 weeks of "deload" that's really just disguised burnout.
// 02 — SIDE BY SIDE
Same lifter, three approaches, six months later. Click to inspect.
What changes when you switch
Pick a program structure and see how it actually plays out across a typical 6-month run.
PPL (6-day) · structurally capped
Origin: Reddit /r/Fitness, 2010s. The default beginner-to-intermediate gym template, owned by no one and copied by everyone.
- 6 days, 1 forced rest day — can't sustain a real 7th without breaking the template
- No deload structure — "deload when you feel like it" usually means never
- Stalls on big lifts — in our experience many lifters plateau around weeks 8–12 of a static split
- Recovery is optional — foam roll, stretching, all bolt-on if you remember
- Individual weak points often get whatever is left over after the main lifts
- Joint complaints — elbows and shoulders commonly flare when intensity stays high without variation
- Missed sessions when the gym is busy — no substitution playbook
Bro Split · the look hides the lag
Origin: 1970s–90s Weider-era bodybuilding magazines. One bodypart per day, hammered to oblivion.
- 5–6 days, one muscle per day — legacy bodybuilding template
- 7-day frequency per muscle — well below the hypertrophy sweet spot of 2–3×/wk
- Mind-muscle weak on whatever the template underprograms for that lifter
- No functional work — CNS shows up to the lift unprepared
- No recovery rule — foam roller stays in the corner
- Imbalanced physique by month 6 — chest-dominant, weak posterior, narrow back
- Looks the same at month 12 as at month 4 once newbie gains plateau
Hevy · the social logger
Origin: 2018, modern logger with social features. Free tier plus optional Pro.
- Routines built in — stronger than a blank log, but still depends on you choosing what to do next
- Social feed — strong category feature; Eccentryx currently stays local/sample-first, not a shipped network feed
- Manual changes — routine edits and load changes still need your judgment
- Logger-first workflow — excellent if the main job is recording sets, history, and social proof
- Hevy Trainer exists — program generation and progressive-overload suggestions are available for Pro users; Eccentryx is testing a narrower browser-first planning flow
- Honest take: strongest comparison if you want social logging. Eccentryx is making a different local-first bet.
Use Hevy if you want a polished logger and social training history. Use Eccentryx if you want a local, no-wearable-required planning flow on any phone.
SensAI · the wearable-signal path
Origin: watch-led training tools. Strong if you want a wearable to lead the loop; different from a browser-first gym-floor plan.
- Wearable-first — useful when your training habit already starts from device signals
- Signal dependent — the loop is only as useful as the data stream and the action you take next
- Rack context missing — a watch does not know when the cable row is taken or when you need a same-pattern swap
- Eccentryx path — answer the setup, build the week, open Gym Mode, and log the set locally on any phone
- Honest take: choose wearable coaching if you want the watch to lead. Choose Eccentryx when the floor plan, swaps, and local log matter more.
SensAI reads your HRV and sleep. Eccentryx uses your setup answers and local set log — no wearable required.
Fitbod · automatic workouts, short arc
Origin: 2015, automated session app. Paid subscription — see current store listing. Heavy mainstream traction.
- Auto-builds each session from your last log + body-part fatigue model
- No long arc — sessions are independent, no mesocycle structure, no deload weeks
- Volume drift — without periodization caps, automatic planning can creep into junk volume over time
- Limited context inputs beyond muscle-group fatigue
- No recovery / functional phase — one block per session, lift only
- Paid plan — Eccentryx has no billing flow live today and adds a 7-day-with-deload structure, local set logging, and gym-floor tools
- Honest take: tactically clever daily generation; less focused on one visible 7-day deload loop.
Caliber · human coach + app, premium service
Origin: 2020, real human coaches via app. Pricing varies by coach, plan, and support level.
- Human coach — weekly check-ins, plan adjustments, accountability
- Real coaching IP — this is the closest thing to a personal trainer at scale
- Coach-led pricing — human coaching cost depends on service level; Eccentryx's current phone app is free, not a coaching replacement
- Limited reach — a coach-led model serves fewer lifters than a browser tool that lets people test the gym-floor loop first
- No built-in load logic — the coach has to catch every adjustment, which makes the coach the bottleneck
- Honest take: Caliber is the high-touch path. Eccentryx is the local tool for lifters who want clearer gym-floor actions before paying anyone.
MacroFactor Workouts · progression-first training app
Origin: progression-first training app — polished programming, exercise guidance, and a paid-app feel.
- Progression model — useful comparison for load, volume, and program progression inside a selected training direction
- Technique support — useful comparison for lifters who want exercise instruction alongside programming
- Paid app — pricing, trial terms, and ratings change over time; check the current store listing for today’s details
- Protocol flow — starts from a chosen training direction; Eccentryx starts from time, equipment, lagging areas, recovery signals, and constraints
- Current Eccentryx proof — a local 7-day plan, Gym Mode, substitutions, deload structure, and export control
- Honest take: MacroFactor is a strong progression benchmark. Eccentryx competes on clarity, local control, and gym-floor execution — free, in this browser.
The safe public distinction is current-state: Eccentryx builds a local week from your answers and keeps the next gym action visible.
Eccentryx · built for repeatable weeks
Origin: 2026, built from Safwan's own gym-floor notes, missed weeks, equipment swaps, and the lessons most static splits ignore.
- 7 days, every day, structured around your weak points
- Mandatory deload every 4th week — non-negotiable, not optional
- 3-week intensity wave: ramp → push → volume → deload, on loop
- Recovery inside every session — foam roll + stretch matched to what you trained
- Selected emphasis on whatever lags — back, delts, arms, legs, chest, traps, forearms
- Joint guardrails for elbows, shoulders, knees, lower back — baked in
- Substitution library — busy gym, hotel gym, missing equipment, all handled
- Next target — logged sets update the local next-target display inside Gym Mode
Current Eccentryx focus: turn a short setup and local logged sets into clearer next actions — no wearable, no food log, no DNA.
What this gets you: clearer deload decisions, fewer avoidable overreach weeks, and a body that feels more consistent at month 12 than it did at month 4.

| Day 7 | Tempo / paused variations + mobility |
| Day | Sample focus |
|---|---|
| Day 1 | Push + upper chest + arm volume |
| Day 2 | Pull width + delts + steady-state finisher |
| Day 3 | Push strength + back thickness + EMOM core |
| Day 4 | Shoulder spec + mid-back + selected weak-point work + intervals |
| Day 5 | Posterior chain + glute focus + steady-state |
| Day 6 | Arms + lateral delts + density circuit |
| Day 7 | Anterior legs + calves + active-recovery cardio |
Train 7 days. Deload week is still 7 days — load and volume drop, but you don't skip sessions. Consistency is the adaptation. Your real plan picks specific exercises, weights, and substitutions based on your equipment, training context, and weak points.
What this gets you: a plan built around your body, not a stock template. Your weak points get the priority slot. Your dominant muscles get just enough to maintain. Every gym day has substitutions for every busy-equipment scenario.

EXERCISE ATLAS · Atlas CARDS
The current Atlas loads its gym-floor cards for the lifts, recovery work, and prep movements a gym user is most likely to need first. Each card answers setup, target feel, fallback, progression rule, and asset status.
Open the lift. Know the setup.
The Atlas keeps each lift practical and conservative: setup, target feel, substitutions, progression, and clear boundaries when pain changes the question.

// 23 — WHO THIS IS FOR
Honest answers before you sign up. We'd rather you opt out now than churn at month two.
Who this is for, who it isn't
Eccentryx is for you if…
- You can commit to training most days. Even on a deload week, you're still showing up — just lighter.
- You've outgrown beginner programs and want a real long-arc structure.
- You care about joint longevity as much as PRs.
- You want a planner that routes around your real context: lagging muscles, busy gym, missed days.
- You want recovery, mobility, and lifting in one place — not three different apps.
Eccentryx is NOT for you if…
- You're brand new to the gym. Start with a 3-day full-body for 6 months first.
- You only train 2 days/week and want to keep it that way.
- You compete in powerlifting/bodybuilding and need sport-specific peaking blocks.
- You're rehabbing a serious injury — see a PT first; come back after.
- You want an 8-week shortcut. This is a year-long arc, not a cut.
- You don't want to log anything. The dashboard, tracker, and future review both depend on logged data.
// 24 — FAQ
The honest answers to the questions everyone asks before joining.
Frequently asked questions
Do I really have to train 7 days a week?
Yes — that is the program. The reason it works is that recovery is built inside every session (foam roll + targeted stretch matched to what you trained). You leave each session restored, not destroyed, so the next day's training is sustainable. Skipping the recovery phase is what breaks people, not the daily frequency itself.
What happens if I miss a day?
You roll forward, not catch up. If you miss Day 3, your next session is Day 4 (not Day 3 the day after). The substitution library handles busy-gym days too — if your bench is taken, you swap to the listed alternate that hits the same muscle. The plan tolerates real life; the only rule that breaks it is skipping deload weeks.
How is this different from RP, Jeff Nippard, Athlean-X, or other programs?
Three differences. (1) 7 days a week with recovery built into every session — most programs are 4-6 days with mandatory rest days; we put the recovery inside the lift. (2) Selected emphasis — your lagging areas get priority, while someone else's plan can emphasize a completely different routine. (3) Access before billing — no $129 ebook, no card, and no subscription gate before you can test it in the gym. The rest of the design uses plain training principles: RPE-aware targets, scheduled deloads, substitutions, and clinician-first pain boundaries.
What equipment do I need?
The personalizer asks what you have access to and builds your plan around it. Full commercial gym is ideal but not required. We have substitution paths for: home gym (barbell + adjustable dumbbells), dumbbell-only setup, cable-and-minimal, hotel/travel gym, and bodyweight + bands.
What if I get injured?
A future safety mode is planned. Logging pain or an injury should flag affected lifts, suggest conservative training modifications, and keep clinician-first language visible before it is treated as shipped behavior. It will not diagnose you or replace rehab or physical therapy. Sharp, persistent, or radiating pain stops the lift and belongs with a licensed clinician.
Why is it free right now? Where’s the catch?
No catch. We’re bootstrapping — no investors, no runway pressure, no quarterly growth targets. The fastest way to get Eccentryx in front of real lifters is to make the app free and improve it from real gym usage.
What happens to my plan?
Your generated plan is yours — it lives in your browser’s localStorage and the generator is deterministic, so the same answers always rebuild the same plan. Keep using what you have, export it when needed, and use the phone app shell in the gym.
Do I need to cancel anything?
No. There is no subscription, no card, and no billing flow in this app surface. You can erase your local data any time from Settings.

Trust documents
Privacy
Plain English: Eccentryx keeps your training history, plan, readiness scores, and tool outputs in your browser’s localStorage by default. If you sign in, selected training records can sync to your server-side account so they can follow you across devices. Sign-in uses an essential Secure HttpOnly cookie; browser JavaScript cannot read the ID token.
- What this device saves: email, first name, primary focus, signup date, member ID, tracker history, PR records, readiness scores, generated plan, calculator outputs, settings, theme, and units.
- What can leave this device: records you choose to sync after signing in; waitlist signup details you submit when email delivery is configured — email, first name, primary focus, consent, timestamp, attribution, and basic request metadata — plus anything you export, share, email, or send yourself.
- What we never collect: address, phone, payment details, photos, biometrics, precise location, or wearable data.
- Cookies / analytics: one essential Secure HttpOnly sign-in cookie when you use an account; no advertising or analytics cookies. We do not use Google Analytics or third-party trackers that build cross-site profiles.
- Email use: waitlist signup can notify Eccentryx. Future launch/access emails require a working sender and an opt-out path.
- Data sale / sharing: We never sell your data or share it with advertisers. If signup delivery is configured, service providers process only the details needed to notify Eccentryx.
- Browser storage boundary: local browser storage is not a cloud backup. Private browsing, clearing site data, device storage pressure, or browser-managed cleanup can remove local records. Use Settings → Export after important sessions.
Terms of service
Plain English: use Eccentryx as a training reference, not a license to ignore your body. The plan is a default; if it tells you to lift heavy and you have an injury, scale it back or stop. We can change the product over time. Eccentryx is fitness software, not medical advice.
- Eligibility: 18+. If you’re under 18, train under a coach or guardian.
- Acceptable use: personal use only. Don’t scrape the generator, resell the plans, or use the API at scale without written agreement. Coaches/studios who want a B2B tier — contact us.
- Plan ownership: the plan you generate is yours. The generator is ours. Same answers always rebuild the same plan deterministically — that means your plan can be reconstructed from your inputs at any time.
- Free access: the current app surface is free to use, with no card required.
- Service changes: we will keep shipping. Sometimes a feature changes shape. Material removals get a dated notice here before they affect the app.
- Missed a week? Rebuild or roll forward from your saved plan. We never hit you with “restart from scratch.”
- Accessibility: Built with accessibility in mind. If something does not work for you, email us and we will fix the product surface.
- Termination: either side can end the relationship at any time. We will not delete your generated plan from your device when you leave; that’s yours.
- Liability: Eccentryx is provided as-is. We do our best, but software has bugs and bodies have limits — you accept responsibility for the lifts you choose to do.

Plain English: there is nothing to refund today because this app surface has no live billing flow. No card is required, and no subscription is created.

Health disclaimer
Plain English: Eccentryx is fitness software, not medical advice. The plans, readiness scores, macro calculators, and floor tools help organize training. They are not a substitute for a clinician, registered dietitian, or licensed coach. If you have an injury, condition, are pregnant, or are returning from a layoff — see a professional first.
- If a lift causes sharp, persistent, or radiating pain: stop. See a clinician.
- If your resting heart rate is consistently elevated, sleep is consistently broken, or you experience chest pain or unusual shortness of breath: see a doctor before continuing the program.
- The macro and TDEE calculators are estimates from population averages (Mifflin–St Jeor). Real metabolism varies; tune from the scale + how you feel over 2-3 weeks.
- Floor Desk is a local software guide. It cannot diagnose, treat, or prescribe. When pain, injury, or medical context is involved, stop guessing and use a qualified professional.

- Delete your local account record: Settings → Account → Leave free account. Removes the local account record on this device. For remote account deletion, email eccentrxx@gmail.com with subject “account deletion” until an in-app deletion path ships.

// 06 — ABOUT
About Eccentryx
SD
// FOUNDER
Safwan Dobashi
I built Eccentryx because most programs failed the exact moment I needed them: mid-week, mid-set, in a busy gym, with no clean answer for what to do next. The point is simple: know the next useful set, keep the plan on your phone, and log honestly.
eccentrxx@gmail.com · Send Safwan a session log or product note. Manual review when available.
// RECEIPT STANDARD
Public before/after claims stay offline until Eccentryx has consented photos and matching month-by-month logs.
No stock physiques, no staged before/after panels, and no progress claim without a real training record.
I built Eccentryx for the exact gym moment where most plans fail: the rack is taken, the week is off, your body is giving you a signal, and you still need a clean next set.
The emphasis is deliberate, but it is not universal. Traps and forearms lead my own weeks right now — but your plan leads with whatever lags for you: chest, legs, back, delts, conditioning, mobility, or recovery. Eccentryx routes the week around the person, not around my current routine.
The app-first model is deliberate. Eccentryx has to earn trust between sets before it asks for anything else. The current planner is free — no card, no trial timer. Use it, break it, export it, erase it, and send the session when something real is missing.
Pain stops the lift. Resting heart rate and bad sessions can pull the day down. If a session feels off, scale back, log it, and keep the week moving. The training rule is a default, not a contract. The hardest part of a 365-day plan is often the deload, where the discipline is doing less.
The long-term idea is a physical Eccentryx training floor — a gym built around this exact training philosophy. The website and tools are the proof path before it has a physical address.
