Indoor boot camps are typically offered in gyms or standalone studios that specialize in this fitness trend. The main benefit is that they usually come with all the bells and whistles of having a physical location — lockers, showers, towels and lots of different types of equipment.

For example, the boot camp classes at Atlanta-based True Fitness use TRX suspension systems, battle ropes, plyo boxes, medicine balls, power wheels, gliders, agility ladders, resistance bands and stability balls.

Then there's boot camp workout pioneer Barry's Bootcamp, which relies on standard strength training equipment as well as treadmills for the extra calorie burn that comes from running intervals.

Are They Right For You? Indoor boot camps are a good choice for you if you like a lot of variety and having a roof over your head.

More outdoorsy types may enjoy boot camps held outside the confines of the four walls of a gym. These classes don't provide as much equipment — sometimes no equipment at all — so you'll run and do a lot of body-weight exercises while enjoying the fresh air.

One drawback of these classes is that they may not be held year-round, depending on the climate you live in. When they are in season, though, you can expect variable weather conditions — rainy in spring, hot and humid in summer.

Are They Right For You? If you like the variety of changing weather and terrain and you want to feel like a kid on the playground again, an outdoor boot camp is a good choice.

The tougher step-brother of water aerobics, water-based boot camps are harder to find, but if you live in a major city, you might be lucky enough to have this option. While working out in water provides less impact than working out on land, it also provides greater resistance.

As such, this particular class might not be a good choice for beginners, but other aqua boot camps may be better suited for newbies. Or, you can build up a base of fitness on land, then make your way into the water.

You don't have to enlist in the army to train like a soldier. Military-style boot camps for civilians provide training that's almost as tough as the kind you might receive before going off to war. (It's not free like military training, but you don't have to engage in actual combat, which is a bonus.)

Are They Right For You? If you've been working out for a while (i.e. not a workout newbie), you're looking for a challenge and you're tough as nails (or want to see if you are), consider trying a military-style boot camp workout.

Created by ex-con Coss Marte, ConBody is modeled after the workout Marte did while in prison, which he executed in his 9-by-6-foot cell using no equipment. Conducted in a slightly larger space (but not by much) in his New York studio, classes include a mix of cardio and body-weight strength training exercises that promise to toughen you up.

The prison-style decor and the sound of an iron gate slamming shut played at the beginning of each class add to the tough guy (or girl) vibe. Classes are taught by ex-cons, and you can even get a mug shot photo after class. Or opt to work out at home with their live online workouts for $5 a month.

Marte's goal is to not only get you in fighting shape with his trend-setting concept, but also to raise awareness of the difficulties ex-cons experience trying to get back on their feet after incarceration.
