How to do the Alternating Lying Leg Extension

  1. Start by lying flat on your back on the floor or an exercise mat. Keep your legs extended and arms resting by your sides.

  2. Engage your core muscles by pulling your belly button towards your spine, ensuring your lower back maintains contact with the floor.

  3. Slowly raise one leg, keeping it as straight as possible, to a height where you can maintain control and low back contact with the floor.

  4. Hold the lifted position briefly, then lower the leg back down to the starting position with controlled movement.

  5. Alternate the movement with the other leg, raising it up in the same straight and controlled manner.

  6. Continue to alternate legs for the desired number of repetitions and sets, ensuring smooth and controlled movements throughout.

  7. Make sure to breathe steadily, exhaling as you lift the leg and inhaling as you lower it.

Maintain a slow and steady pace to keep the focus on the core muscles and to prevent using momentum rather than muscle control. It's important to avoid arching the lower back during the exercise to ensure the abs remain engaged and to prevent strain on the lumbar spine.
