It's Time to Kick Your Butt Into Gear -- Step It Up!

If you're looking to squeeze that butt into skinny jeans this fall, I have just the exercise for you. These step-ups target your glutes, hamstrings, and quads and will help you build a rockin' lower body.
This exercise requires a bench or another type of sturdy platform that is ideally at about knee level. While you're stepping up onto the bench, pay attention to a couple of things. Make sure you maintain good posture
 — keep your abs drawn in and don't arch or round your back. Also, control your descent rather than letting momentum drop your body as you're stepping down. If you don't think you can step up very high, find a lower bench to work with — a step stool will do the trick!
Step-ups

1. Stand facing a bench or platform with your feet hip-width apart. Place your left foot up on the bench, making sure your whole foot (including the heel) is firmly on the bench.
2. Exhale as you press down into your left foot and step your right foot up onto the bench. Both feet should be firmly planted on the bench at the midpoint of this exercise. Slowly lower your left leg back to the ground, then lower your right leg. Repeat, completing 12 to 15 reps on your left side before switching to the right side for another 12 to 15 reps.
