Sprint repeats
Mark 30 m; accelerate through; walk back recovery (2-3 min); repeat 6 times.
Muscles
- Primary
- glutes
- Supporting
- hamstrings, quads, calves
Mechanics
- Pattern
- power
- Equipment
- bodyweight
- Geometry
- Variable Range
- Energy model
- Glycolytic Pathway (10-90s)
- Target feel
- Peak neuromuscular output per rep — quality should not decline across sets.
- Progression
- Add reps; shorten rest; add resistance (sled, parachute).
- Regression
- Prowler sprint or bike sprint if lower-body injury limits top-speed running.
Watch for
- Insufficient rest — turns into conditioning, kills power output
- Heel striking at full speed — land midfoot and drive toes down
- Stopping abruptly — decelerate over 10 m past the finish mark
Substitutions
- Box jump
- Assault bike sprints
- Broad jump
