Targets: Legs, glutes, back, core Do: 13-15 reps
(a) Standing with feet hip-width apart and toes facing forward, bend your elbows and raise the bar towards your collarbone (as before). With elbows tucked in and back straight, lower your bum as far as you can for 4 seconds.
(b) Keeping your chest lifted and ensuring that your toes are in line with your knees, use your glutes to return to the starting position, increasing your speed so it only takes 1 or 2 counts. Check out how strong you look in the mirror, then repeat.
