Kettle Bells: My New Found Love

Works the core

Works many muscle groups at one time

Develops explosive energy, and great for cardio

Does an awesome job of improving posture, which helps strengthen the body, and improves breathing.

Kettle Bell Swings happen to be my favorite, but there are a number of exercises you can do.

I actually made my own adjustable kettle bell with a bar bell, one weight with cut outs for handles, and different lb. weights for the bottom (bell) end, as is seen in the picture below.
