I created my own 30-day kettlebell swing challenge. The two that I found on Pinterest had either too many repetitions or too little. I wanted something that fell in between ~ allthatisgia (February 2015)
The perfect simple workout you can do while watching TV: The kettlebell swing. Literally tones you from head to toe and the aerobic nature of it helps you melt the fat away. You're welcome. :-) While you're at it, check out the book this info comes from: "The Four Hour Body."
