Recommendations: 2-3 Sets, 10-15 Reps
Stand upright with your feet about shoulder-width apart and your knees slightly bent. Hold water bottles at the sides of your body with the palms facing inwards. This is the starting position. Raise the water bottles straight up as high as you can along the side of your body. Exhale during this movement. Hold the contraction briefly (about 1-2 seconds). Your elbows should move back, not out to the sides. Keep your shoulders relaxed. Slowly lower the bottles to the starting positions. Inhale during this movement. Repeat for the recommended number of repetitions.
