The water cup can be one you use daily, or a mineral water bottle. Of course, it should be filled with water and not too small!
1. Sit on a chair with your legs together, left hand holding a water bottle and raising it upwards, right hand bending the elbow to support the left elbow.
2. Inhale, exhale while lowering the water bottle behind by bending the left elbow, then raise it again. Repeat this 15-20 times for each hand.
Second move to slim arms: Leg lift while sitting on a chair
1. Feet apart at one and a half shoulder width, sit on the chair, hands clasped in front of the chest, back straight, close your eyes, relax your body, maintain natural breathing.
2. When inhaling, puff out your chest, when exhaling, let your chest sink down, feel the balance of your body's breathing.
3. Slowly stretch your hands upward, straighten them high above your head, clasp your palms above your head with fingertips pointing up, puff out your chest, feel the stretch in your waist, back, and arms, maintain natural breathing, hold the action for about 10~20 breaths.
