Performing the: A Step-by-Step Tutorial Lying Straight Leg Raise
Keep your lower back pressed to the floor, then slowly raise your legs off the ground while keeping them straight, until they are at a 90-degree angle from your hips.
Hold this position for a few seconds, ensuring your core muscles are engaged and your lower back remains in contact with the floor.
Gradually lower your legs back down to the starting position, ensuring you do not let your feet touch the floor until you have completed your set.
Repeat this exercise for the desired number of repetitions or until you feel a good burn in your abdominal muscles.
