This exercise can be performed on many different pieces of equipment. If using a flat bench, start by sitting sideways on the bench with knees and legs together slightly bent.
Grasp both hands down by your side onto the bench making sure that your hands are parallel to you shoulders. Slowly walk your feet out keeping your legs together and raise your body up until your arms are fully extended. Slowly lower your body bending at the elbows until you've reached the lowest point. Then raise your body back until your arms are fully extended again.
Tip: Keeping your body straight throughout this exercise is extremely important. You can also add in different options on where or how high to place your feet once you're ready to increase more strength.
If using two parallel bars, use similar motion with legs hanging below. Remember, always keep your hands parallel to your shoulders and keep your body as straight as possible throughout entire exercise.
