One of the best movements one can do to widen their arms, is the dumbbell across the body curl.
Well, in this case we are mimicking that exercise by counter pressuring the armpit.
The goal here is to stay in the tension plane for up to 45 seconds on each side.
- 1Stand up straight and put your left hand under your right armpit
- 2With your wrist supinated, bend over slightly and press against the armpit
Note: Tense the biceps hard but not to the point where you are shaking.
