Leg extension machine
Leg extension machine: written movement steps, equipment and example doses. General information to help you choose an appropriate starting point.
How to do it
- Sit with machine axis aligned to knees.
- Straighten knees against shin pad. Keep thighs and pelvis supported. Bend your knees to lower the pad under control.
- 2 sets × 5 reps; 75s rest between sets. Use light resistance or an easy supported setup. Practise the same controlled path on every repetition. Finish with at least 2 comfortable repetitions in reserve. Keep thighs and pelvis supported. Count one complete outward-and-return movement as one repetition; for alternating limbs, each individual limb action counts once.
