Title: 100% Functional !!!
Review: This fitness tool is 100% functional. For one price, I have the kettlebell functionality of several common kettlebell weight configurations. I started off with 35lbs, progressed to 40lbs, and now am at 45lbs. I'm following Pavel's ETB Program Minimum, and have reached 115 reps in 12 minutes, a far cry from what I started out with. I feel good with the kettlestacks in that I know I don't have to spend more money as I get stronger .... the kettlestack will meet all my needs up to 70lbs. If I had went with kettlebells from the start, by now I would have easily spent at least $240, and needed a place to store the extra equipment, and would be planning for my next purchase. No thanks! I don't see why anyone would go with a fixed weight other than novelty reasons. If you really need another KB, get another kettlestack!
