Quasi-unilateral: Read on the Internet

Interesting thoughts from Geoff Neupert's site about double/single handlebell training, http://chasingstrength.com/ (LINK):

...Great question, Robert. I would call double kettlebell work “semi-unilateral” or “quasi-unilateral” for the following reason.

The stimulus on the body as an organism is very similar to bilateral loading as with a barbell in the legs and hips, but then because the kettlebells move independently in the hands, this affects the arm and shoulder musculature similarly to unilateral loading. Notice I said “similarly.” You will most likely still be able to press more in one hand with one kettlebell than being able to put that same weight in two hands.

For example, if you can press the 48kg for one rep, it does not mean that you can press a 48kg in each hand for one rep. (It doesn’t necessarily mean you can’t either…)

So to get good at doubles work, you most definitely need a base of singles work (less going on in the brain, easier to control and master body positioning, internal cueing, feedback, etc), but you really need to practice doubles work. It’s another “same but different” form of training....
