Mondays are a drag, but planks definitely don't have to be!
- Support your bodyweight face down
- Flat towards the ground, palms down, arms extended actively pushing away from ground
- Feet shoulder width, knees/butt/quads squeezed
- Actively sucking belly button in, place one weight to the left of the body at belly height
- Right arm drags the weight from the left to the right side while the left arm supports bodyweight, then switch arms
