Knee Raises Guide

The Knee Raise exercise primarily works the Rectus Abdominis muscle (Abs) with secondary emphasis on the obliques and Transverse Abdominis muscles (Core). This is an isolation exercise where you lift your knees up towards your chest while hanging from a bar or support.

Here's the step-by-step: Lie flat on your back, hands placed by your sides or under your back. Pull your knees into your chest. Fully extend your legs and keep your heels 2-3 inches off the floor. Pause for half a second and repeat. Show less Show more.
