Are you ready to challenge yourself?  This 20-minute workout is guaranteed to leave you dripping in sweat.  Prep yourself with a short active warmup, and then HIIT it with this workout made up of two circuits with some cardio bursts in between.  Grab some dumbbells, between five and 10 pounds, and follow NYC-based celebrity trainer Adam Rosante.

When it comes to quick and effective workouts, nothing beats a boot camp!  This 15-minute sweat session mixes cardio bursts with strength training to double the benefits of your workout.  Grab a dumbbell between five and 10 pounds, press play, and then bring it!  And do watch the Pretty.  Strong.  series premiere Tues., Oct. 6, at 10 p.m./9 p.m. Central on Oxygen.

No matter how you feel about strength training, neglecting core work is a serious no-no!  When your ab and back muscles are equally strong, they work together to support your entire body in almost every activity, from running to gardening.  This quick core challenge works your abs from all angles and targets the back and glutes, too.  Get ready to feel the burn in your core, which we think is a great thing.

We've made a kick-ass workout featuring just two moves:  the squat and the plank.  There are so many effective variations of these classic exercises, but we manage to fit five of each into this quick 10-minute workout.  Plus you don't need any equipment for this bodyweight workout, so you can do it anywhere.  Press play, and get ready to get moving!

It's time to lift, tone, and round out your butt.  Strong, toned glutes are essential to staying injury free and increasing your performance in all kinds of athletic endeavors.  This workout is perfect for getting a bigger, stronger booty, as well as toning whatever assets you've got.  Grab a set of weights — we recommend dumbbells between five and 10 pounds — then press play to build a better backside.
