Recommendations: 2-3 Sets, 8-12 Reps
Stand upright with your knees slightly bent to reduce stress on your lower back and your feet close together. Hold water bottles with an overhand grip (palms facing down). The arms should be straight and the bottles should be in front of your thighs. This is your starting position. Curl the bottles up in an arc until they touch your chest. Do not use your shoulders or rock your body. Your elbows should come forward slightly, but not out to the sides. Exhale during this movement. Slowly return to the starting position. Inhale during this movement. Repeat for the recommended number of repetitions.
