Bicycle

Lie on the floor. The lower back should be pressed to the floor. Place your palms on the back of your head. Be careful not to injure your neck. Raise your shoulders as you would for a normal crunch. Raise your legs so that your knees are perpendicular to the floor, and your shins are parallel to it, as shown in the figure. This will be your starting position. Now slowly imitate the rotation of the bicycle pedals. Stretching the right knee, pull the left towards you. As you exhale, pull your right elbow towards your left knee. On an inhale, return to the starting position. As you exhale, twist in the opposite direction, bringing your left elbow closer to your right knee. Repeat the exercises until the desired number of repetitions is completed for each side.
