Have you seen anyone doing this? Ever? It definitely works her abs and engages the shit out of her core, but imagine going into a gym and doing it for yourself in front of everyone there – you’re going to look stupid. Not because you don’t know what you’re doing, but because no one there will have heard of this workout and will think you’re just some scrub with a bunch of rubber bands.
I’ll stick to doing planks, curls and Russian twists, thank you very much.
