Basic Sit-Ups Steps
Lie down on a mat. Keep your legs hip-width apart, bend your knees, and place your feet flat on the floor. Keep your hands on the sides of your thighs (or at the back of your head), and push your lower back to the floor. Engage your core. Keep your neck in line with the spine, look diagonally up at the ceiling, and inhale. Exhale and use your core muscles for sitting up. As you do so, your hands will slide up from your thighs to your knees. Keep your shoulders relaxed. Inhale and slowly roll back down to the starting position. Make sure your lower back is lying flat on the mat. Again, exhale and sit up. Do 3 sets of 5 reps before moving on to 8, 12, and 15 reps.
Basic Guidelines To Do Sit-ups Correctly
Always push your lower back to the floor so that it is completely on the ground. Place a rolled towel underneath if you cannot fully push the lower back to the floor. Do not strain your neck by tucking it in. Place your fingers behind your back and keep your arms open. Do not slouch.
