VARIANT 01
A.K.A. One-Leg Leg Extension
Seated on the machine keep your abs tight and head straight. Extend one leg out fully squeezing the quadriceps and coming back slowly without going past 90 degrees, and repeat.
Adjust the seat back and foot pad of the leg extension machine so that when you sit in it your knees are at the edge of the bench and your ankles are just below the foot pad/rollers.
Sit back with your back pressed firmly against the back pad. In this position your knees should be lined up with the pivot point of the machine arm.
Grasp the handles or the seat edges behind your hips and keep your upper body stable as you extend your right leg until it is fully extended in front of you.
Contract the quad muscles at the top as hard as possible and then slowly lower the weight under control to the start.
Complete the desired number of reps with the right leg and repeat with the left leg.
You can also do alternating reps for each leg if preferred, which gives each leg a short rest between each rep.
This can allow you to complete more reps with a given weight.
