Oblique crunches

Lie on the floor. Press your lower back to the floor. Put one hand behind your head, leave the other on the floor near the body. Put your feet on the bench. Now lift the shoulder of the hand that is behind the head, performing twisting. Stretch your shoulder and upper body forward, trying to touch your knees with your elbow. For example, if you put your right hand behind your head and perform a right shoulder raise, you should touch your right elbow to your left knee and vice versa - your left elbow touches your right knee. After touching your knee with your elbow, return to the starting position. Don't forget about breathing. During the eccentric (lowering of the body) part of the exercise - inhale, during the concentric (lift) - exhale. Perform the required number of repetitions, alternating sides.
