My body has been completely transformed from 15 years of running. I'm 5'7" and 135 pounds at age 41. My face looks thin, I have a better body than most 20 year olds. I gave myself the best gift that I could possibly give myself.
If they could distill 15 years of running (5x per week) and put it in pill form, I truly believe it would be the most valuable thing medicine has ever created.
All it takes is 45 minutes per day for 5 days per week. And you can actually have fun while doing it! It takes a long time to get to that point but it's so worth it.
