Tuck Up
The Tuck Up is an effective core exercise that targets your abdominal muscles.
- Start in a seated position with your knees bent and feet flat on the floor.
- Lean back slightly while keeping your back straight.
- Lift your feet off the ground and tuck your knees towards your chest.
- Hold for a moment, then lower your feet back to the starting position.
How to perform the Tuck Up
- Set up. Set up in a stable, balanced starting position appropriate for the Tuck Up using your body weight.
- Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your abdominals.
- Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.
Coaching cues
- Move with intent — every rep should feel deliberate, not rushed.
- Drive force through your abdominals rather than momentum.
- Keep your breathing steady: exhale on the hard part, inhale on the reset.
Common mistakes
- Using too much weight and losing positional control.
- Cutting the range of motion short and missing the target muscle.
- Letting your spine round or hyperextend instead of staying neutral.
