Ladies, I’ve got a new challenge for you (okay, men can do this challenge as well)! Over the course of the next month, I want you to be able to perform 100 non-stop bodyweight back extensions.

If your normal workout includes back extensions, take them out since you’ll be performing 12 sessions of them with bodyweight this month.
The first day should be fairly easy…most folks can achieve 20-back extensions pretty easily.read more
