Push your luck
Back away from the bench. The piston press gives you more stability with none of the drawbacks
Among trainers in the know, Bosu is often sniggeringly lengthened to Both Sides Useless, and for good reason. By wobbling atop one to do your biceps curls and squats, all you’re doing is reducing the amount of weight you can lift, making your workout less effective. Lie down, however, and the perspective shifts.
‘Everyone wants to bench as much weight as they can, but that’s not great for your shoulders,’ says Gym Jones trainer Rob MacDonald (gymjones.com). ‘It’s better to increase the challenge of the move, without lifting more weight, to work your muscles harder.’ You’ll do this via the piston press, a move that forces you to brace and push at the same time. In stable condition? You will be.
