Tuck Crunch

How to Do It

1. Lie flat on your back with your knees bent and feet flat on the ground.
2. Place your hands behind your head with your elbows pointing outwards.
3. Engaging your abs, lift your shoulder blades off the ground and bring your knees towards your chest, simultaneously curling your upper body towards your knees.
4. Pause for a moment at the top, then slowly lower your shoulder blades and extend your legs back to the starting position.
5. Repeat for the desired number of repetitions.
