Dear Coach: Are Double or Single Kettlebells Better?

After reading Andrew's article on how to build muscle in grapplers, a reader has a question - does he really have to use double kettlebells for the routine, or can he get the benefits using one?

Dear Coach,

Hey, this is a question for Andrew Read or whoever can answer it really, but in regards to the article on Adding Muscle with Kettlebells: How I Build Up My Grapplers, is it a must to use two kettlebells simultaneously? Or will doing one on one side and then switching work?

Thanks,

One Lump or Two

Dear Lump One or Two,

The routine can be done with either one or two kettlebells, but you won’t get the same result. One of the keys to quickly forcing change in your body is load, and with only one kettlebell you’ve only got half the load on the body.

That’s not to say you won’t get great benefits from grip strength or conditioning, but when it comes to gaining muscle from a workout like this having two kettlebells makes all the difference. I also believe it gets the fighter used to having lots of weight on them for long periods of time, like they’re forced to endure when working on the bottom while grappling.

Looking at some of the research on the jerk it shows great transfer to increasing speed and power when used in loads of roughly one third of body weight. So while you won’t get the mass gains like you will with two bells you will be able to train speed better. If I were training an MMA fighter I would now use both single and double bell workouts to address both sides of the force/velocity curve – heavy doubles for force production and a lighter single bell for speed. For grapplers, however, I’d just stick with the double bells as they don’t have the same need for speed that a striker does.

About Andrew Read

Andrew Read is like that old guy in the Rocky movies - he has a funny accent, hates everyone, and no one ever knows if he's happy or sad. But just like Mickey, he knows training.

Even back in grade school his teachers would complain he was spending too much time reading bodybuilding magazines or trying new exercises in the gym. These days nothing has changed and even after a lifetime of competitive martial arts and some time spent in special forces he still maintains that same passion for increasing human performance, especially that go all day, out run a zombie, live in an apocalyptic wasteland kind of fitness.

Having been a Master RKC, Andrew is recognised as one of the best kettlebell trainers in the world.His specialty is elite performance and he has been involved with training three world BJJ champions.
