Straight-Back, Stiff-Leg Deadlift
You need a barbell for this exercise but start with a light weight until you feel comfortable, to avoid injury to your back. Hold the bar in front of you, arms extended and loose, with an overhand grip. Keeping your back straight, lower the bar as far as you can towards your feet by bending your hips. You can bend your knees slightly too but the focus should be on your hips. Then return to your original position, straightening first your hips, then your knees. Great for the glutes and works the hamstrings too.
Using the aerobic step again, simply step onto it with one foot, pushing through the heel to lift your whole body and the other foot up as well. Step back down, leading with the other foot and repeat 10 times. Then do it all over again, starting on the other foot. This exercise primarily targets the calves and glutes.
Heel Lift Squat
With your feet about the width of your hips apart, lift your left heel clear of the floor. Now lower your bum by pushing back with your hips, raising your arms in the air at the same time. When your thighs are roughly parallel to the floor, return to the starting position. After 10 reps with your left heel raised, do the same with your right heel off the floor. Works quads and glutes.
