ROTATIONAL PUSH-UP
Yes, this exercise builds upper-body and core strength. No, you don’t have to do it without a shirt on for it to work.
How To Do It
• Get in a push-up position with your hands shoulder-width apart on the floor
• Lower your body until your chest is near the floor
• Push your body up; as you ascend, raise one arm and hand toward the ceiling and twist your torso
• Repeat and raise the opposite arm and hand
