Arm Circle Planks: 30 Seconds
- In a plank position, reach your left arm back and then circle it overhead, bringing your palm back to the floor; repeat on the other side. This counts as one rep.
- Continue for 30 seconds, keeping the core stable and the belly button pulled up toward the spine.
- The wider your feet are, the more stable you will be. Do not let your pelvis drift toward the ceiling.
