Mechanics

Pattern
horizontal press
Equipment
bodyweight
Geometry
90° Alignment
Target feel
Chest loads at bottom; serratus fires at top as scapulae protract.
Progression
Elevate feet, add a weight plate to the back, or slow the eccentric to 4 seconds.
Regression
Incline push-up with hands on a bench reduces load by ~30%.

Watch for

  • Sagging hips — loses core tension and loads lower back
  • Elbows flaring to 90°
  • Head dropping instead of keeping a neutral neck

Equipment context

Bodyweight exercises need no equipment, but progression depends on leverage and position rather than added load.
