Description

Single-leg leg extension focuses on controlled movement and maintaining proper body alignment throughout the exercise. The goal is to create tension where needed while avoiding unnecessary strain or momentum. This helps improve movement quality, joint stability, and overall physical control.

Instructions:

  1. Seat yourself in the machine and adjust it so that you are positioned properly. The pad should be against the lower part of the shin but not in contact with the ankle. Adjust the seat so that the pivot point is in line with your knee. Select a weight appropriate for your abilities.
  2. Maintaining good posture, fully extend one leg, pausing at the top of the motion.
  3. Return to the starting position without letting the weight stop, keeping tension on the muscle.
  4. Repeat for the desired number of repetitions.

Exercise FAQ

How should I program this in a workout?

Use it after your warm-up when you’re fresh. Aim for 2–4 sets and choose a rep range that matches your goal (strength: lower reps; muscle: moderate reps).

What should I do if I feel it in the wrong place?

Check your setup, slow down, and reduce weight. If discomfort is sharp or in a joint, stop and choose an easier variation. Think of it as controlled movement done with repeatable, clean reps.

What’s a common mistake people make here?

Rushing reps and losing body position. Keep the movement smooth and repeatable so tension stays where you want it. Think of it as controlled movement done with repeatable, clean reps.
