Performing the: A Step-by-Step Tutorial Tuck Crunch
In a smooth motion, bend your knees and bring them towards your chest while simultaneously lifting your upper body off the ground.
Make sure your elbows are wide and try to touch your knees with your elbows, contracting your abdominal muscles as you do so.
Hold this position for a second, ensuring your abs are fully engaged.
Slowly lower your body back to the starting position, keeping your abs engaged even as you extend your legs and lower your upper body. Repeat the movement for your desired number of repetitions.
