Attach the Theraband or rubber tubing to a stationary object on the floor. You can also simply stand on the band as well! Grasp the other end of the band in your hand.
In addition to the thicness or resistance of the band, the more stretched the band is the greater the resistance will be so you may have to experiment and find or position the band to match your strength levels.
The band or bands should be stretched along the outer side of your body. Your arms should be bent so your hands are slightly outside your shoulders.
Exhale and press your arms above your head. Inhale as you bring your arms back to the starting position.
Perform the required number of sets and repetitions and don't forget to make a note on how the exercise felt to you!
