How to do the Alternating Leg-Cross Crunch
Lie on your back on a comfortable surface, with your legs extended and your arms reaching overhead, touching the floor.
Engage your core by pulling your belly button towards your spine.
In a fluid motion, raise your right leg off the ground and simultaneously lift your upper body off the ground, reaching your hands towards your lifted foot. Try to touch your foot with your hands or reach as far as you can towards your foot while keeping both legs straight.
Lower back down to the starting position with control. Your shoulders and leg should lightly touch the floor or hover just above it.
Repeat the same movement with the left leg, lifting it towards your hands as your upper body comes off the ground.
Continue to alternate legs with each repetition, keeping the movement controlled and the core engaged throughout the exercise.
Perform for a set number of repetitions or a set time interval, ensuring to maintain proper form and controlled breathing.
It's important to keep your movements slow and controlled, focusing on the contraction of the abdominal muscles. Avoid using momentum to perform the exercise, as this can reduce its effectiveness and increase the risk of injury.
