How to do Cable Seated Leg Extension

01
Setup
Adjust the seat height so your knees are aligned with the pivot point of the machine and attach the ankle cuff to the low cable pulley.
02
Setup
Securely fasten the ankle cuff around one ankle, ensuring it is snug but not constricting, and sit upright on the bench with your back pressed against the pad.
03
Inhale, then exhale as you slowly extend your leg forward by contracting your quadriceps, pushing the weight away until your leg is fully straightened but not locked.
04
Hold the peak contraction for a moment, then inhale as you slowly and with control allow the weight to pull your leg back to the starting position, resisting the urge to let it snap back.
05
Complete all repetitions on one leg before switching to the other, maintaining a consistent tempo and focus on the quadriceps contraction.

Tips

To maximize quadriceps engagement, focus on a strong contraction at the top of the movement, squeezing your thigh muscles as if trying to push your shins forward.
Control the eccentric (lowering) phase, taking 2-3 seconds to return your leg to the starting position; this increases time under tension and promotes muscle growth.
Keep your torso stable and pressed against the back pad throughout the exercise to isolate the quadriceps and prevent momentum from assisting the lift.
Ensure the ankle cuff is positioned just above your shoe line, not on your foot, to apply direct resistance to the shin and optimize quadriceps activation.

Common mistakes

Using excessive momentum or swinging the leg reduces quadriceps activation; instead, select a weight that allows for a slow, controlled movement through the entire range of motion.
Hyperextending and locking out the knee at the top can place undue stress on the joint; instead, stop just short of full lockout, keeping a slight bend in the knee to maintain tension on the quads.
Letting the weight stack drop quickly on the return reduces the effectiveness of the exercise; instead, actively resist the weight as it lowers, controlling the eccentric phase to maximize muscle engagement.
