The kettlebell revival is in full swing, and since these traditional Russian weights re-emerged as a training tool, the way they are seen by regular gym-goers has changed significantly.

A few years ago, people looked at the strangely shaped objects, weren’t sure how to use them properly and ultimately steered well clear. Now they look at the strangely shaped objects and still aren’t really sure how to use them — but they give them a go anyway.

So while the popularity of kettlebell training has rocketed, understanding of good technique is lagging behind. That’s why MF has come to get the lowdown from leading kettlebell coach Mike Mahler, who is over from the US to teach a two-day workshop for trainers and bell (the aficionado’s term) lovers. We’ll be doing basic moves on day one, then more advanced double bell and stacked (two bells in one hand) stuff on day two.

KETTLEBELLS: GET IN THE SWING OF THINGS

I think my technique is pretty good, so I’m expecting to breeze through day one, although I might struggle in day two. But straight away I realise that my swing, the most basic move, is fundamentally flawed. “Don’t let the bell pull you forwards because that will hurt your back,” says Mahler.

He advises me to retract my shoulders and avoid locking my elbows at the top of the move.

We also do a drill in which we swing the bell, but keep our arms close to our sides to make sure power comes from the hips, rather than using your arms and shoulders. “If you swing the kettlebell away from your body too early that puts stress on your lower back,” he says.

Shoddy form is something Mahler is used to seeing and he thinks it’s the first thing you should address. “You want to make sure that you fine-tune your technique before you go up to heavier weights,” he says. “Avoid overusing tension and be as fluid as possible. The mistake people make is trying to force the work rather than being efficient and using good technique.”

He’s also keen to point out exactly why we’re putting ourselves through any of this. “I like the ballistic nature of the exercises and the full-body element. And I like the emphasis on the posterior chain — all the muscles that you don’t see in the mirror. Pretty much every guy needs to work on his posterior chain more.”

We continue to work our posterior chains by doing drills for one-hand swings, cleans and snatches. Mahler also likes supersetting moves and pairing the renegade row with the rolling floor press (see over the page for form guides), which works your chest and back while hammering your abs and getting virtually every other muscle in your body to help stabilise the movements. They’re fun, full-body moves and look cool too.

DOUBLE TROUBLE

Day two is significantly harder and using two kettlebells instead of one seems to be more than double the difficulty. We start with a stacked press, which means shoulder-pressing two kettlebells in the same hand.

It may look like it’s a show-off move, but there’s a sound reason for doing them.

“It forces you to use the optimal pressing grip and arm position,” says Mahler. “If you take the kettlebells out wide, forget about it. The leverage changes so it’s harder to stabilise the movement. It’s not just stunt lifting.”

I manage to clean two 16kg bells into position but I’m struggling to press them overhead. Mahler, not surprisingly, has no such difficulty and demonstrates a double-stacked press with two bells in each hand.

An easier double-bell move is the bent-over row hold, in which you row one weight up to your side, then do reps with the opposite arm. “The ability to hold the weight in a contracted position will make you stronger,” he says.

Sadly, it doesn’t make me immediately stronger, so when I do the next move, an iron cross (where you start with two kettlebells overhead, then slowly lower them out to the sides before raising them overhead), I manage to lower two 16kg bells down to the side, but they’re not going back up again.

SIMPLE AND COMPLEX

When we’ve gone through all the moves, Mahler tells us how to integrate them into workouts. You can create complexes by stringing moves together, such as doing double snatches, double clean and presses, double swings and double cleans with squat thrusts in between. “If you don’t want a complete departure from the stuff you’re already doing, you can use kettlebells as a finisher,” says Mahler. “Do swings or snatches at the end of a workout. Or replace exercises that you normally do with dumbbells.”

You can also use kettlebells to prepare for big lifts. “I like to do ballistic exercises at the beginning of a workout so I’ll do lots of sets of double kettlebell swings with low repetitions. That fires up my nervous system before I move on to heavy deadlifts or presses.”

After two days of swinging, pressing, cleaning and snatching, my nervous system is feeling a lot more fried than fired up. But I finally feel as though  I have nailed the basics of using kettlebells with confidence. And one day that stacked press will go up.

THE ANATOMY OF A SWING

The two-hand swing is the most fundamental kettlebell move. Here’s how to perform it properly.

> Bend your knees slightly, pushing your bottom back, to get into the starting position. Make sure that your back is flat and keep your head in a neutral position.

> Swing the kettlebell between your legs forcefully as if you were passing a ball to someone behind you. Quickly reverse the direction and drive through with your hips, taking the kettlebell to chest level.

> Let the kettlebell swing back between your legs and repeat.

> Remember that the swing is a posterior-chain exercise and this is where all the power is generated — it’s not a front raise.
