After just 30 days on ATP Extreme my 405lb back squat went from 6 reps to 10 reps, which is a 60% rep increase. That’s huge. I also noticed that my recovery times are much faster and my endurance is way up due to less lactic acid. Now my training volume is way up, but I still feel fresh coming into every workout. ATP Extreme has been very beneficial to me as a crossfit athlete because it truly does affect all aspect of my performance.
