Twisting in a plank position fires up the core and challenges your stability.
- Begin in a plank position with your belly button pulled in toward your spin and glutes tight while holding a one-kilogram dumbbell in each hand. Keep 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 rise or drop.
- Bring your left hand back to the floor, and repeat this action on the other side to complete one rep.
