Description

Ball leg curl 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. Begin on the floor laying on your back with your feet on top of the ball.
  2. Position the ball so that when your legs are extended your ankles are on top of the ball. This will be your starting position.
  3. Raise your hips off of the ground, keeping your weight on the shoulder blades and your feet.
  4. Flex the knees, pulling the ball as close to you as you can, contracting the hamstrings.
  5. After a brief pause, return to the starting position.

Exercise FAQ

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 curling done with repeatable, clean reps.

How can I make this exercise harder without adding a lot of weight?

Slow down the lowering phase, add a brief pause in the hardest position, or increase total reps while keeping form crisp. Think of it as curling done with repeatable, clean reps.

Which muscles should feel like they’re doing most of the work?

You should feel the target muscles working while the rest of the body stays braced. If a joint or the lower back is doing the heavy lifting, reduce load and tighten your setup. Think of it as curling done with repeatable, clean reps.
