How to do the Lying 90-Degree Leg Tap Crunch

  1. Start by lying flat on your back on a comfortable surface with your hands placed gently behind your head without interlocking your fingers.

  2. Raise your legs so that your thighs are perpendicular to the floor and your calves are parallel to the floor, creating a 90-degree angle with your knees.

  3. Engage your core muscles and perform a crunch by lifting your head and shoulders off the ground, aiming to bring your chest towards your knees.

  4. As you crunch up, extend one leg out, keeping it off the floor and as straight as possible, while tapping the opposite elbow to the opposite knee.

  5. Without lowering your head and shoulders to the floor, switch legs and elbows, performing the leg tap and crunch with the opposite limbs.

  6. Continue alternating sides for the desired number of repetitions.

Remember to breathe out as you perform the crunch motion and inhale as you return to the starting position. Keep the movements controlled and focus on using your abdominal muscles rather than pulling on your neck or using momentum.
