Isometric Biceps Hold with Towel
Twist a large towel so that it is in a long straight line. Step onto one end of the towel with your right foot, grasping the other end of it in your right hand (palm in front of hip facing outward). Keep feet slightly apart, knees slightly bent.
Allow enough tension to feel resistance as you curl your right hand in towards your chest. Hold (with tension) at 90 degrees for 30 seconds. Step further away and hold at 45 degrees for 30 seconds. Switch sides and repeat for one set.
Adjust resistance by stepping closer (more difficult) or away (easier) from the end of the towel in your hand. You should feel enough resistance during each part of the exercise (may need to adjust it by stepping further away from hand at each different angle mentioned). Be sure not to hold breath.
