As a former user of P90x, I was disinterested with the same workouts over and over again, leading me to stop using the program all together. What ATHLEAN-X does that is different than the competition is provide us with a new, different workout every day. Not only will this variety keep you interested, you will partake in a technique called muscle confusion. Muscle confusion will keep your muscles guessing and prevent the dreaded plateau. I really love your program Jeff keep up the great work.
