When starting out using clubs, I would definitely start with 1 pounders, nothing bigger. Looking back now, I kind of wish I bought 2 pounders, instead of 5 pounders, for my second pair, but that's OK. It will just take me longer to grow into them. I'm making progress.

Another thing I use are 2 pound pilates balls to kind of change things up. You hold these with an open grip, vs. a closed grip for the club, so it works the muscles a little differently. Plus, they're a lot cheaper than clubs. About 10 bucks for the pair vs. 50 bucks for a pair of 1 pound clubs.

Most of the time when I'm using these things, I just work on one arm at a time. Two reasons. The first reason is, it's just easier to concentrate. Second reason is, my TOS is bilateral, so pulling on both arms at the same time can cause a flare easier.
