I could understand that. It takes time to slowly move up to where I'm at. I super set 4 rounds 6 to 12 reps heavy as I can for every lift. My lifts aren't extremely heavy. They're probably the upper tier of the common persons weight but you have to remember that's when I'm super setting.

My philosophy on lifting comes from almost every top tier lifter. Listen to any of the top dogs and id say 99.9% of them say "Go Heavy! And Go Hard!". Lift heavy as you can and make sure it's doing something. If you're not getting a workout then you're not gonna grow. You're gonna be the old lady that hops on a machine and pushes 10 pounds 400 times then goes home.

You watch the pros and their form isn't 100% on point every rep. Sure it's probably good to get a variety. Strategically planning out a nice variety to get the muscles to grow under various stress modes. The first few sets or last few could be lighter and focused on form. Somewhere in the equation needs to be heavy enough where you're getting the muscle to grow bigger. More stress(within reason), the more muscle will eventually grow to handle the work load. I find it hard to believe people when they say every rep needs to be so light you and slowly pull down, pause, slowly release. I'm p sure this behavior is only going to take you so far. You need to go heavy to move upward.

On the contrary some guys form is so far away from the exercise it's not hitting the muscle at all. So there needs to be a smart strategically designed program, that you'll probably only get through years of trial and error.
