Leg Extension (Machine)
Also called Leg Extension, Leg Extension (Gym Machine)
How to do it
Adjust the machine so your knees align with its pivot and the pad rests above your ankles. Extend both knees until your legs are nearly straight, squeeze your quadriceps, then lower the pad slowly to the starting bend. Keep your hips against the seat and avoid kicking or locking the knees forcefully.
Setup
Adjust the seat so both knees align with the machine pivot and the shin pad rests just above the ankles. Sit with the back and hips against the pads, hold the handles, and begin with both knees comfortably bent.
Where you should feel it
Across both quadriceps as the knees straighten, with the strongest contraction near the top. Keep the hips against the seat and avoid forcefully snapping the knees locked.
When to use it
Use for stable bilateral quadriceps hypertrophy and controlled knee-extension strength without balance demands. Sets of 8-20 reps work well.
