About that bowling ball I found....
Me and "Sir Lucius Theodore Ghetto-Ass Kettlebell" spent a few minutes together this evening.
I picked it up, swung it behind my left knee, raised it over my head, did a triceps press, and swung it behind my right knee. I then repeated that motion 50 times.
Things I feel: Low back, shoulder girdle, upper arms, and (I'm assuming the expensive kettle bell wouldn't deliver this last part) my finger flexors and intrinsic hand muscles got a workout.
Things I won't do: Lay on my back and throw it into the air over my face and catch it.
Me and Bowling Ball are on a mission now. I feel all swole.
