Instructions:
- 1Start by lying flat on your back, with your arms and legs spread out in the shape of an 'X'.
- 2Raise your right arm and left leg, reaching across your body to perform a crunch and touch your right hand to your left foot.
- 3Lower your arm and leg back to the starting position. Repeat with your left arm and right leg.
- 4Continue alternating sides for a full set.
- 5The movement should be smooth and controlled, with each crunch performed from the contraction of your abs, not from momentum or pulling on your head or neck.
Tips:
- Ensure your lower back remains pressed against the floor throughout the exercise.
- Exhale as you reach across your body, and inhale as you return to start position.
- Make sure you are twisting your torso and not just moving your limbs.
- If the exercise is too difficult, modify it by bending your knees.
