ABS
Plank Body Saw
A plank with a sliding forward-and-back motion, which turns a static hold into a moving stability challenge. The extra travel forces the abs, obliques, and lower back to fire harder to keep you rigid.
How to do it
- 1
Lie on your stomach with elbows bent to 90 degrees directly under your shoulders.
- 2
Keep your palms down or in fists with forearms parallel and toes tucked under.
- 3
Brace your core and lift your hips and knees so your body forms a straight line from shoulders to heels.
- 4
Push through your toes and elbows to slide your body forward, then rock it back.
- 5
Keep your lower back flat and body rigid throughout the sawing motion.
