If I could do it all again I would try lifting with super high reps for the first 6 months or a year. Like 50 plus rep sets, 75 reps, maybe 100. I'd do this in order to build a better mind/muscle connection.
I think in my early years of bodybuilding I was pretty much just moving the weight and not getting good muscle contractions. I lifted moderate heavy to heavy and I gained some strength and some mass but it took me many years to be able to really feel my muscles working. I could be wrong, but I think super high reps in the early stages would have helped me make more progress and make it quicker. It's almost all a waste of time because I was drug free and my gains were modest but I wish I could test this theory.
I train sometimes now with these super high reps and I've made some pretty good progress with it even as a 40 year old dude. I realize now that even though I thought I was training hard at age 18 I was really just fucking around. I was reading all this bullshit in bodybuilding magazines and it took me a long time to understand the reality of training as a natural. I had fun, but the truth is I wasted a lot of time and a lot of money following bullshit "advices".
I think most of us did the same thing. When i started lifting in high school it was due to playing sports. The coaches wanted us to be heavy and strong. We never did more than 8 reps on anything, lots of sets in the 3-5 rep range. I did get strong, but i never really understand the mind/muscle connection until many years later.
If i could do it all over again, i would never have gotten into competitive power lifting, due to injuries i'm dealing with today nearly 20 years later. And i would have trained mainly in the 10-15 rep range. Use mostly DB's. Also, i would have focused on eating clean and staying lean most of the year.
I think high reps have a place, but what i've noticed is my form goes to shit after about 20 reps on anything.
I always tell new lifters to train for a pump and learn how to stimulate and flex your muscles correctly. Learn the proper range of motion for constant tension.
But everyone just wants to max out on bench and call it a week.
