Triceps Side Stretch
This stretch is the opposite of the standing biceps stretch, and acts upon the triceps—the muscles on at the back of your upper arms. It is important to stretch muscles that are antagonists to one another—that work against each other—so that a flexibility imbalance does not develop. This is true for strength training as well, as having a strength imbalance can actually pull your posture out of alignment, causing spinal issues.
To Perform the Triceps Side Stretch
1. Bring your right arm across your body, over your left shoulder, and hold your elbow with your left hand.
2. Pull until you feel a stretch in your tricep. Hold for 10-20 seconds, and repeat with the opposite arm.
