Anyhoo, long story short, I bought these for myself and they've saved my forearms (and I have a feeling they might work a wee bit better than legwarmers although the concept is basically the same). http://kettlebellinc.com/products/showproduct.php?prod_id=99 These things are really great. Well worth the 20 bucks (well, $21.95 or whatever it was with shipping).
I have some of those, too. I bought them in a package with Lisa's book and DVD, which I really like.
I must say I wear my tennis wrist bands much more often. I found that the "No Fear" wrist guards don't breath or absorb sweat, so it accumulates under them, making them kind of yucky after a sweaty workout session. (And I spent under $6 total for a pair of long, thick wrist bands).
