list_alt Step-by-Step Instructions
Adjust the seat height and backrest of the machine to fit your body.
Sit on the machine with your back against the backrest and your feet on the footpad.
Grasp the handles or sidebars for stability.
Extend your legs forward by straightening your knees, lifting the weight.
Pause for a moment at the top, then slowly lower the weight back to the starting position.
Repeat for the desired number of repetitions.
warning Common Mistakes
Recruiting larger muscle groups to "help" move the weight instead of isolating Quads — swinging momentum or shifting the torso takes tension off the muscle this exercise is meant to train.
Locking out too fast or letting the elbows drift outward under load — controlling the eccentric (lowering) phase is where most of the muscle-building stimulus happens.
Not adjusting the seat/pad height to match body proportions, which puts the joint outside its natural line of pull and reduces the exercise's effectiveness.
Progressing the load or reps too quickly before technique is consistent across every rep of every set.
person Who Should Do This Exercise
Lever Leg Extension is classified as a Intermediate strength exercise, so lifters with some training experience who already have basic technique and stability in place — beginners can work up to it, but should master fundamental Upper Legs movements first.
