Plank and Rotate
- Begin in a plank position holding a five-pound dumbbell in each hand, keeping your wrists stiff to protect the joints. Open your feet a little wider than hip distance.
- Lift your left hand to the ceiling, twisting through your entire torso — keep the motion smooth and controlled. Your pelvis will rotate, but keep it level without letting it raise or drop.
- Bring your left hand back to the floor, and repeat this action on the other side to complete one rep.
- Do 10 to 15 reps to complete a set.
Twisting in a plank position fires up the core and challenges your arms strength, too.
