Where is a good source of how to use and where to buy kettlebells?
I bought my kettlebells from http://www.gillathletics.com/
http://www.muscledriverusa.com/ has them a little cheaper, but I've never dealt with them.
I actually saw kettlebells at Dicks a couple days ago, so you may want to check their prices to see if they'd be cheaper still with no shipping.
For training, there's tons of stuff out there and finally some more is getting published. If Dick's is carrying them now then maybe they are getting mainstream enough to find books at barnes & noble some day. The only book I've read is Pavel's "Enter the Kettlebell" which gives a decent overview.
The only kettlebell exercise that I hadn't seen before as a normal exercise is the swing. Every other exercise is a normal exercise, such as a clean and press. The difference with kettlebells is that the balance is all different which makes the exercises more challenging, and with most exercises you can do the same exercise holding the kettlebell different ways to change how it works your body.
A few weeks ago I posted about my training plan and someone (can't remember who - sorry) suggested looking at kettlebells.
So after surfing around I found these sites to be informative:
There are more, but I got the most out of those three.
As far as where to purchase kettlebells, I havn't got that far yet. The holidays are putting a bite on my disposable income.
Bodybuilding.com has an excellent list of kettlebell workouts.
I bought Ader brand kettlebells. They are very well made, good finish, no rough spots. I purchased them from Berry's Barbells in Columbus, Ohio.
Warning - kettlebells are ADDICTIVE. I'm not sure what it is about them, but I love mine, and would never do without them again.
