Attach a chord to an immobile object or door behind you and lift one foot off of the floor, then take a handle in both of your hands keeping your arms above your head, elbows bent and palms facing upward with your arms at a 90 degree angle and hands near your shoulders slowly straighten out one elbow keeping your elbows in alignment and above your head, contracting your tricep (back of the arm) and then return to the start, making sure to do the same amount with the other side until the set is complete.
