SETUP: Get on your knees (on a mat) and grab an AB WHEEL.
REP: Push your hips forward as you roll the wheel out in front of you. When your elbows reach shoulder level, allow them to hit the ground and push yourself up into a PLANK position, holding the tension for 5 seconds by keeping your abs and lower back engaged. Then raise yourself back off the ground and continue the rep until you’ve returned to your starting position.
TIP: The ab wheel is a piece of kit most folks hit great reps with, so this is a useful alternative exercise.
