Squat with water bottles
Rely only on your bodyweight and start with your feet shoulder-width apart. Squat down as if you’re going to sit on a toilet seat and squeeze your glutes as you stand back up again. Repeat 15 to 20 times. To really tone and achieve a booty like JLo’s, try doing squats while holding a 1.5L water bottle in each hand, curled towards your shoulders, or keep them high above your head (remember to keep those arms straight).
