Statement yes or no? Please leave your comments….

In my opinion a lot of powerlifters is training to heavy. Ofcourse they are making progress only I think on the longterm they have less progress due lack of technique. Do you what my thinking is?
When you train to heavy you train to hard on willpower. Although you want to improve your technique, your body isn’t able to improve the technique. When you training to heavy, your strong points will improve more compare your weak points, so at the end (longterm) you have less progress. Also you when you train more on technique you will get less injures and this also helps you to generate more progression on the longterm. A lot of lifters don’t have the capacity to make a proper, although their squat is making meet depth……… And yes you need heavy (overload) workouts…..
