This move works all of your butt muscles and is one of the all-time best tush toners around, Shoemate says.
How to do it: Start standing with feet together, holding dumbbells on top of each shoulder. Take a wide step forward with your right foot as you bend your knees, lowering your body into a lunge. Both knees should bend at a 90-degree angle, and the front thigh should be parallel to the floor, keeping your knee behind your toes. Stand up out of lunge, and step your left foot into your right. Then repeat the move with your left leg. Repeat 15 times total, alternating legs each time.
Form tip: To help your balance, tighten up your core and focus on keeping good form rather than moving quickly.
