When you think of a gym or a weight room, there's probably a very specific image in your head. An open space filled with heavy iron, benches, cable setups, and if you're in a big box, plenty of cardio stations and machines. Most of the weights are probably barbells, both on squat platforms and benches, or dumbbells, sitting stacked along the wall on a rack.

But there's another strength training implement you should add to that vision. Kettlebells are some of the most versatile, efficient tools you can have in your exercise repertoire—and as this year proved, people love them and consider them essential.

No Gym Required: Kettlebells

No Gym Required: Kettlebells

Thanks to the implement's unique shape, which places the rounded load beneath the handle, kettlebells are perfect for swings, presses, and carries from different positions that you wouldn't attempt with dumbbells. You can work your arms, of course, but also your legs, chest, back, core, posterior chain—really, you can use kettlebells to train your whole body.

The shape of the kettlebell make them an even better option for single-arm, multi-joint movements like cleans and snatches. When the need arises, you can also grab onto a kettlebell's handles, or even the two bars connecting the weight to the handles, sometimes called the "horns," with both hands. That type of grip allows for challenging curls, presses, and more.

There's also an entirely distinct training modality that has gained popularity thanks to the utility of kettlebells: the flow.

You can thread together different movements into one free-moving series, which can then be repeated for maximum effect and combined with other routines to create an entire program (like our Kettlehell series for All Out Studio from kettlebell master Eric Leija).

No matter how you use a kettlebell, it helps to have a game plan. Check out these exercises and workouts for a full catalogue of kettlebell goodness.

Exercises

Kettlebell Front Rack

The front rack isn't so much an exercise as a position you can use to make exercises even more challenging. The front rack can be used for moves like squats, lunges, walks—really anything focused on your lower body. Using either one or two kettlebells, you'll hold the load in such a way (demonstrated above) that you'll be forced to engage your core to prevent your torso from tipping over. Consider the position as a solid way to pull double duty.

Bottoms-Up Kettlebell Press

One of the best aspects of training with kettlebells is the ability to create challenging variations of standard exercises using the implement's unique shape. The bottoms-up press is a prime example of this, adding the extra challenge of holding the bell by the handle and balancing and stabilizing its weight distribution to a shoulder press. You'll be tasked physically and mentally.

Kettlebell Halo

Start off slowly with the basic kettlebell halo. This simple, incredibly effective movement is a great way to build shoulder stability while working the core. Try the exercise for 10 to 20 reps per side to start before adding extra features, like the kneeling position in the video or even a squat, for more of a metabolic impact.

Kettlebell Swing

The swing is one of the most popular and effective kettlebell moves, so mastering the finer points of the form is a must for anyone looking to add the implement to their repertoire. The key here is making sure to emphasize the hip hinge—when you lower the weight down, be sure not to squat—before thrusting to snap the weight up.

Goblet Pulse Squat

Crush your legs with a little bounce with this dynamic exercise. Try 4 sets of 10, resting for 30 seconds between each set.

Double Kettlebell Front Squat

Double up on weights to knock out this lower body exercise. Your upper body will get a challenge, too, since you'll be using your arms and bracing your core to keep the kettlebells in the racked position. Try 3 to 4 sets of 10 reps, lowering down into position slowly and pausing at the bottom to create a ton of tension.

Turkish Getup

This multi-part movement takes some time and coordination to master, but it's an effective full body exercise once you nail every step. Keep the weight light to start (run through the first few times without any), then add heavier loads as you progress.

Kettlebell Clean and Press

The clean and press is another multi-joint, multi-part exercise that works your whole body. Make sure to keep the weight controlled as you clean into the racked position before pressing straight up. If you're bold, set a timer for 5 to 10 minutes, then alternate 5 reps per arm for the whole period.

Kettlebell Abs Series

The kettlebell can also be a useful tool to sculpt your abs. Since you can easily hold and maneuver the implement, you can use it as a load for some traditionally bodyweight movements. Check out these six core moves from Leija's Kettlehell program. You'll learn basics like the bride to situp, two-step getup, Russian twist to quick twist, pullover to situp, and weighted hollow rock.

Full Body Kettlebell Moves

Swings too much for you? Try these exercises instead: the kettlebell clean, goblet squat, kettlebell thruster, and reverse lunge. Perform 4 sets of 12 reps of all or any of the moves individually, or hit them back-to-back as a circuit with no rest as a workout that will torch your whole body.
