Knee raises, also known as knee-ups or knee tucks, are a core exercise that targets the abs and hip flexors. To perform knee raises, start by hanging from a pull-up bar or other stable object with your arms extended and your legs hanging straight down. Lift your knees up towards your chest by bending your hips, then lower your legs back down to the starting position. Repeat for the desired number of reps.
In CrossFit, knee raises are often used as a conditioning exercise or as part of a high-intensity workout that includes other bodyweight exercises or weightlifting movements. The number of reps and sets can be modified to suit different fitness levels, and the exercise can be combined with other core exercises to create more challenging variations. Knee raises require proper form and technique to prevent injury, and they are often taught by a qualified coach to ensure safe and effective execution.
