Ever wonder how guys who exclusively work out on monkey bars get so ripped? This bodyweight workout is the answer. And since it's pretty much equipment-free, you can use it to whip yourself into shape pretty much anywhere. It'll work just as well outside on a summer day or in a bare-bones garage gym.

Here's the best part: You'll not only burn fat and build muscle with just three exercises, you'll also learn one of the secrets that street gymnasts use to bang out dozens of pullups and dips: the 10-to-1 method.

Option A

How it works

The circuit we’ve designed here doesn’t let up. When you train any squat variation, plus the pullup and the dip, you work nearly every muscle in your body, and your heart will race to supply them with blood and oxygen. Performing a decreasing number of reps—10 to 1—helps you keep the workout going even as you get fatigued. It'll also get you leaner, and build the endurance that'll build the fitness you need to rattle off a high number of reps in one shot. Plus: Feel free to use this workout to win bar bets about how many pullups you can do.

Directions

Perform the exercises as a circuit, completing a set of each in turn and resting as little as possible between sets. Repeat for 10 circuits (until you’re doing only one rep per exercise).

Option B

A lack of training equipment doesn’t necessarily doom you to a workout consisting only of pullups and pushups. With a little creativity, you can still train like an animal (you’ll get the reference below) while targeting your entire body. This workout is outside the box—so much so, in fact, that you’ll have to go outdoors to do it.

How it works

This routine requires a park or playground area with monkey bars and plenty of open space. You’ll use classic (albeit under-prescribed) bodyweight exercises like the bear crawl and crab walk, which you probably haven’t tried since your days in summer camp. As you’ll come to remember, they’re not easy—especially for a grown man well north of 100lbs. They require a lot of work from your heart, lungs, and core. Later, the parallel bar hand walk will blow up your grip and forearms; the sprints will fry your legs.

Directions

Perform the exercise pairs (marked A and B) as supersets, so you’ll complete one set of A and then one set of B before resting. Repeat until all sets are complete. Note that the parallel bar hand walk is done as straight sets—do a set, rest, and repeat. This workout combines well with bodyweight option A, so if you want to integrate them both into a training week, perform A first, rest a day, and then perform B. (You can also add in option C, coming up next.)

Option C

Combining exercises whenever possible helps you work more muscles in the same amount of time. These hybrid moves allow you to get the benefit of six exercises in a workout that actually prescribes only three.

How it works

This workout can be combined with the previous two for a three-day-per week program done in the order shown. Or, combine it with either one of the two previous workouts and alternate them throughout the week.

Directions

Perform the exercises as conventional straight sets, completing all sets for one exercise before moving on to the next. If you can’t perform 10 reps for a particular set, do as many as you can without going to failure (end the set with one or two reps in you) and then rest a few moments. Continue when you can to complete the remaining reps.

Option D

OK, we’ll admit it: Sometimes the odds are really against your getting a workout in. You may well find yourself stuck without weights or bands, only to find that you also forgot to pack your suspension trainer. There’s nothing to pull on, so you can’t work your back, and you can’t even improvise with the objects around you. We’re not sure just what kind of place this would be, short of a jail cell (and if that’s where you are, hey, we’re not judging), but we can give you a great workout to do, even there.

How it works

All you need is something to step on, be it a park bench, a large rock, or a chair. But if you have nothing elevated on which to step, you can substitute a lunge for the stepup. To target your back, which is usually unworkable without having at least a bar of some sort to pull on, we’re employing the “blurpee”—as made famous by fitness expert Tim Ferriss, author of The Four-Hour Body. The wider foot placement used in the blurpee requires more work from the lats to pull the hips and legs forward as the body comes back from the pushup position. (The extra “l” in blurpee stands for “lats”.)

Directions

Perform the exercises as conventional straight sets, completing all sets for one exercise before moving on to the next.
