I started following the ATHLEAN-X training program in 2011 and like most people that work out I was looking for the quick answer. I never wanted to do cardio, running just didn’t appeal to me so at one point I was just lifting and kept getting bigger. Once I found ATHLEAN-X that all changed their was no running involved but their burst workouts were tougher then cardio. They are so much more fun and appealing to me. You are burning fat while gaining muscle at the same time, they are super high intense but short at the same time. This has helped me change the way I train. Thanks again Jeff.
