Instructions
Set up two weight plates next to each other or a low box on the ground under a Smith barbell.
Position a loaded Smith barbell at a level that allows you to grip it at waist level with your arms fully outstretched.
Step on to the weight plates with the balls of your feet.
With a tight core and flat back, raise yourself up driving through your calves. Pause briefly at the top of the raise.
Slowly lower yourself down but do not touch the ground with your heels.
Repeat.
