2. Tighten your gluteus maximus and abdominal muscles and straighten your legs and arms completely. This is your initial posture. Start lowering yourself to the ground while keeping your legs completely straight and your feet together. Bend the elbow nearly 45 degrees, neither too far outward nor in line with the upper arm.
Continue to lower your body until your head is about to touch the ground. Once you reach the lowest point, push your hands hard, keep retreating, tighten your hips and torso, and return to your original position. Repeat this action a specified number of times.
