Overview

Bent-knee sling sit-ups develop power in the core and upper-body. Bent-knee sling sit-ups provide a good strength base in the abs before progressing to medicine ball throws. This is a good exercise for anyone looking to take their ab training to the next level.

Description

• Sit on the floor with your legs in front of you, knees bent.
• Roll your body back and down, stretching your arms behind your head.
• Then throw your arms up and toward your legs while sitting up.
• Repeat for a specified number of reps.

Mistakes

• Not throwing the arms fast enough to create momentum to assist with sitting up.
• Letting the chin jut out (instead of staying tucked).
• Feet rising from the floor.
