Seated Leg Curl

How to Seated Leg Curl

Seated leg curls (also referred to as leg extensions) are an excellent isolation movement for your thighs. They help to develop and tone your quadriceps (quads) – or the front, upper part of your legs.

How to do Seated Leg Curls / Extensions:

Start Leg Curl Exercise

Leg Extension Finish

  1.  Select your weight and sit on the leg curl machine with your legs and feet under the pad (feet pointed forward). Some leg extension machines will require you to load free weights, others will incorporate a locking plate system. You will need to adjust the pad so that it sits on top of your lower leg (just above your feet). The bottom of the seat should rest directly behind your knees, sitting comfortably.
  2. Extend your legs to the maximum. Using your quads, hold for a slight moment at the end of each contraction.
  3. Let the weight come back down in a controlled manner, keeping a contraction the entire time.
  4. Repeat for the recommended amount of repetitions.
