How to do the Leg Extension - Learn Proper Leg Extension Form
- Step 1: Sit on a leg extension machine. Position your legs under the pad and grasp the side bars with your hands. This is the starting position.
- Step 2: Extend your legs to the maximum, exhaling as you do so. Pause a second in this contracted position.
- Step 3: Lower the weight back to the original position as you inhale. Make sure your legs don't go past the 90-degree angle point.
- Step 4: Repeat for the desired number of reps.
Leg Extension Variations and Leg Extension Alternatives
- Variation 1: Experiment with different foot positions.
- Variation 2: Perform the exercise with one leg at a time.
Leg Extension Tips
- Tip 1: Adjust the pad so that it is just above your feet. Your legs should form a 90-degree angle between the upper and lower part of your leg.
- Tip 2: Make sure the rest of your body remains stationary on the seat of the machine when you extend your legs.
