Story time.
I'm not a bodybuilding expert or a guru or a bro-scientist. I'm not a doctor or a personal trainer so don't take this as advices. I'm lifetime natural and while I look great for my age I've never been on a bodybuilding stage. My entire adult life I've bought into the idea that to grow bigger muscles you have to lift heavier weight. In my younger years that's exactly what I did. I always thought that training in high rep ranges was for definition. I kept my rep ranges between 8 and 10 most times. Sometimes I'd go lower or higher just to mix things up. (Muscle confusion principle)
Well time passes and shit happens. I don't live very close to a gym anymore and I don't have the same amount of time to work out that I did in my 20's. Thus I've been lifting at home with nothing more than some hex dumbells. I've been training super light just because I don't have ultra heavy weights. You could say I kinda fell ass-backwards into high rep ranges. On most of my exercises I've been in the 30 or 40 rep range and I increase it when I can. As an example my last set of one armed overhead tricep extensions I hit 50 reps with a 30 pound dumbell. My muscles were really knotted up after that.
I've been surprised to see that not only did I keep my size, I've actually grown. I'm looking the best I have in years and I'm feeling swole. What does it mean? Maybe nothing, but I thought I had heard a while back that time under tension (at least 30 seconds) is a big factor in hypertrophy. I don't know if that's true but I've been pleased my results the last couple years lifting like this. Years ago I would have scoffed at the idea of doing 40 plus rep sets but now that's me. Anybody else out there training light and doing stupid amounts of reps just to up the intensity? Any comments, praise or criticisms? Personal attacks and mockery are ok too.
I'm not going to do this forever but for now it's an interesting experiment.
