Raise Those Heels
Heel raises may seem like you are barely working, but you know you did something when you feel the soreness the next day. You can even use ankle weights for added resistance and to build more strength.
To do this booty building routine, get on all fours, and slowly kick each leg towards the ceiling, keeping your knees bent. For an even better workout, finish one side before switching legs, rather than alternating – this doesn’t give your muscles time to rest, leading to a better workout. Spend about 45 seconds on each side, lifting the legs slowly to really feel the burn in your glutes.
