Twist Crunch (Legs Up)
Perform the Twist Crunch with your legs elevated to engage your core effectively.
- Lie on your back with your legs raised and knees bent at a 90-degree angle.
- Place your hands behind your head, keeping your elbows wide.
- Engage your core and twist your torso to one side, bringing your elbow towards the opposite knee.
- Return to the starting position and repeat on the other side.
- Continue alternating sides for the desired number of repetitions.
How to perform the Twist Crunch (Legs Up)
- Set up. Set up in a stable, balanced starting position appropriate for the Twist Crunch (Legs 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 quadriceps.
- 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 quadriceps 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.
