The BOSU knee tuck is a dynamic abdominal movement performed on a BOSU ball or other stability training device. It primarily targets the rectus abdominis or "six-pack" muscles of the core. It can be performed for time or reps as part of an ab-focused workout or a circuit involving body weight or the BOSU ball.
Benefits
More difficult than bodyweight knee tucks
Stability challenge from the ball forces the abs to work harder to stabilize
Draping back over the ball between reps can increase the stretch on the abs
