Pattern
knee flexion
Equipment

Geometry
Variable Range
Target feel
Hamstrings shorten against the pad; no hip lift until final rep.
Progression
Add load; introduce a 2s pause at peak contraction.
Regression
Seated leg curl if prone position causes low back compression.

Watch for

  • Hips popping up to cheat range — removes hamstring stretch
  • Jerking the concentric — tension lives in control
  • Stopping short at the top — cuts peak contraction

Equipment context

The machine fixes the movement path, reducing stabilizer demand and letting you focus on the target muscle.
