SIGNS YOU’RE DOING IT WRONG

You’re twisting your hips

‘This is an exercise in stability. Keep your body as rigid as possible,’ says du Preez.

You’re drifting to one side

‘Improper form when you’re transferring weights may result in a shoulder injury,’ says Faulmann. Keep it slow and even.

You’re only lifting with your arms

‘Lead with your elbows and contract your lats (the muscles on the side of your back),’ advises Faulmann.
