How to do leg extensions

- Extend the knees through a comfortable controlled range without lifting the hips or throwing the weight.
- Pause briefly, then lower the pad slowly to the same starting position. Keep the weight stack from crashing down.
Better reps before more weight.
Start with a version you can control. Record the same setup and range each time. Add reps or a small load increase when you can repeat the movement without changing the technique.
