The Bodda Getta

These are very good kettle bells and a 24kg will set you back around 75. Also if you search the web you can usually find 10 percent off coupons. Now on the weight subject it depends on what you are wanting to do with it. I started out lighter because I like high rep workouts with my bell. Also I weigh only 165. But I started with 14 and have since purchased more.

The 24kg can be a beast, at your size I don't think you'd have a problem doing the swings with it. But depending on what kb regimen your are following, the 24kg may be a little too big for some of the other exercises. I weigh 205 and swing a 30kg. It feels like I'm swinging a wrecking ball! For something like one-handed snatches I'd probably have to use a 16kg or 12kg. Just my 2 cents.

This is true....form is always key.

I exercise all the time and am in good shape. An ortho said kettle bell is the worst exercise around and he will be seeing a lot of patients from it down the road. He is head ortho for a major college too. Try TRX if you are 275lbs. Not sure you need more size or lbs.
