Hold a high plank with shoulders over wrists with a weight in front of your right hand. Remember to breathe. Keeping your spine and hips still, lift your left hand and move the weight to the left. Pick up your right hand and move the weight to the right. Repeat.
Do: 60 seconds
Benefits: Moving the weight is a way to challenge and strengthen your core (hello obliques!). You are going to want to lean and twist to move the weight, so keeping the spine still and stable is key.
