This is a trailer to Mark Sisson's 21 day challenge.
I love seeing the before and after pictures! It makes me reflect on my own pictures/results from earlier this year.
Because of this challenge, my life has changed and I became passionate about health/fitness.
Since then I have shared my story with others, started a blog, created my own 21 day challenge for others similar to Mark Sisson's, and have people telling me about their amazing results!
I couldn't be more happy.
