Recommendations: 2-3 Sets, 6-10 Reps
Get into a squat position, glutes on your calves. Hold water bottles with your hands about shoulder-width apart and your palms facing up (underhand grip), triceps just above the elbows resting on your kneecaps. This is the starting position. Curl the bottles up to your chin. Your upper arms should stationary throughout the entire motion. Exhale during this movement. Squeeze the biceps and move the elbow out about 1-2 inches. This movement will work the long head of the biceps where it crosses the shoulder joint. Slowly lower the bottle to the starting position. Inhale during this movement. Repeat for the required number of repetitions.
