Recommendations: 2-3 Sets, 8-12 Reps
Stand upright, with your knees slightly bent and your feet shoulder-width apart. Hold water bottles, with the palms of the hands facing inwards, and let it hang at your sides. Your elbows should be close to your body. This is your starting position. While holding the upper arm stationary, curl your hands forward and upward, while contracting the biceps. The hands will rotate to an underhand position. Exhale during this movement. Continue the movement until your biceps are fully contracted and the dumbbells are at shoulder level. Continue by moving the elbows slightly forward (about 1 inch) to ensure the long head of the biceps is fully involved (the long head of the biceps crosses the shoulder joint) while you squeeze the biceps. Slowly bring the bottles back to the starting position. Inhale during this movement. Repeat for the recommended number of repetitions.
Step 2
While holding the upper arm stationary, curl your hands forward and upward, while contracting the biceps. The hands will stay in an underhand position. Exhale during this movement. Continue the movement until your biceps are fully contracted and the dumbbells are at shoulder level. Continue by moving the elbows slightly forward (about 1 inch) to ensure the long head of the biceps is fully involved (the long head of the biceps crosses the shoulder joint) while you squeeze the biceps.
