Just declaring you have the best butt ever is not a workout. But Equinox, offers a variety of classes, including best butt ever. Since dudes tend to ignore

their own backsides, this class that focuses on leg and glute strength can be a great addition to your routine.

Spinning is not just for girls. It's pretty hard core. But, it's hard to motivate yourself alone on a bike to keep the high intensity needed for a good workout. Spin

class is a different story. The instructors don't play and they keep you moving no matter what. Try Flywheel. They show how your doing on a big screen in the

front, so you can add some competition to your workout.

Another fitness craze known for being popular with women, Jillian Michaels is a tough as nails and her workouts can make any man sweat just as much as their lifting

routine. A mix of cardio and strength training, you'll be tired at the end of this. She also features a challenge move and if the woman in this video can

do such baller trice, push-up, burpees, you have no excuse.

Crunch Gym was the first to offer a lot of group classes and they're still on top of their game. Broga is obviously aimed at men and combines

yoga, functional fitness moves and high intensity intervals. It gets it a good stretch with an even better workout.

Boxing. You can't claim that boxing would be some frilly group class. Title Boxing Club offers a 30-min boxing workout. It may sound easy, but believe us, it's not.

If all the other workouts still seemed too easy, this one will break you. Barry's Bootcamp is legendary. People swear by them and have been totally transformed. The dude in

the picture went from kinda skinny to super ripped, just cause of Barry's. If you don't have a Barry's near you, there's lots of bootcamps all over the

country to fulfill your fitness needs.
