I have been training just under two years, my lifts are okay but not spectacular. Only 300 raw wilks. I have recently been doing 5x5 training and I got to and past failure every workout, and I walk like I got f***** up the ass all the time. I just got a trainer because I've decided to take my lifting seriously and I would like to compete at the international level within 5 years, I am only currently 21. My trainer says that I only really need 2 good sets in a workout, but he said I can do 5x5 and I should be ok, but I am only allowed to go to fail once in 3 weeks on each lift. How do you guys do your workouts? How often do you got to fail?
