Stand facing the barbell, holding the end of the barbell close to your chest in both hands with your elbows tucked in to your sides.
Drive though the balls of your feet to raise your heels off the ground, squeezing your calves, with a focus on making sure your ankles do not turn out or in.
Lower your heels back down to the ground and repeat for the desired number of reps.
