Although I am co-owner of a gym in Philadelphia, and I want people to come to my gym to workout, it mystifies me that so many folks think you need a gym to workout. The reality is you can get many places and achieve many goals just by having one of these...
Combine kettlebell training with bodyweight training and you have plenty of workouts at your fingertips. You can train outside, in your garage, at the park, at the beach, on your lunch break, on vacation, or practically anywhere for that matter.
The kettlebell provides a portable training system, that's easy to store, and in the larger scheme of things costs practically nothing after the initial investment. So if you can't make it everyday to the gym, there's always time to do a quick twenty minute workout that involves you and your kettlebell.
Here's one just for fun...
