Hello Sir,

There are lots of different training approaches and I am quite sure each of them have their own benefits. However I find Progressive overload training approach to be the most effective. And the reason it will more likely work for most of the athletes is PROGRESS.
Every day I see athletes in the gym throwing around weights with no training plan and idea what they are trying to accomplish, these people look exactly the same all year round and never change. I always ask to myself, why would you go to the gym 5 times a week to look exactly the all year round or how can you come to the gym not knowing which body part you are going to train!!!
Anyway Progressive overload training approach requires discipline and right mind set, that's why you do not see many athletes doing this however in my eyes that is the most effective way to get to some successful results.

Regards

Powerlifters do it. But for only a few reps, considering for that sport its about the burst followed by a slow decline, then you burst again. For extended reps you may see a huge increase in size....from your tendons popping.

Slow negatives can cause connective tissue inflammation. It’s not at all necessary to stimulate hypertrophy. Anyone who tells you otherwise is trying to sell you something. It’s a useful tool in the toolbox, but by no means an indispensable one. If you’re interested in avoiding injury instead of just getting big at all costs, I wouldn’t do heavy negatives to try to stimulate hypertrophy. I’m not saying it won’t work, I’m saying it may not be worth it.

So I use a lot of slow negatives in my training but it’s part of my rep scheme, not forced negatives to failure. I just find I get more out of controlled reps and focusing on the squeeze. But the whole forced negatives thing I don’t see being practical. Way too much trauma for the muscle on a daily basis.

If it makes your pickle drip, then go for it. Not really necessary IMO. If done, though, it should be done sparingly.
