Recommendations: 2-3 Sets, 8-12 Reps
Sit on a chair, with your feet flat on the floor. Hold water bottles with your hands about shoulder-width apart, hanging down to your sides. Your palms should face inward. 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 to the front about 1-2 inches. This movement will work the long head of the biceps where it crosses the shoulder joint. Slowly lower the bottles to the starting position. Inhale during this movement. Repeat for the required number of repetitions.
