I'm quite experienced in fitness and bodybuilding by that I mean I have been lifting weights for about 5 years, I'm not professional nor fitness "guru" or expert in anyway but I'm still always asking myself if I should go full range of motion when doing exercises for every muscle group.
There are so many different opinions some say full range of motion is better than partial range and vice versa.
When I perform exercise with partial range it helps me to get constant tension on muscle I'm working on, and I can train with heaver weights and I definitely get better pumps than going "Full". I'm not sure, for example, why many personal trainers recommend doing, let's say, dumbbell press exercise really carefully I mean they would say: don't go lower than your eye or ear level. I always feel that I can go lower and not hurt myself and the same thing is with other exercises. Wouldn't going lower engage more muscles to work harder and wouldn't it help to build muscle faster in the long run? It seems that if your primary goal is health when doing partials is more suitable and of course I believe that doing "full range" puts you at higher risk of injury.
Personally, I like both ways and it looks like they both do work but would you suggest me doing full range of motion all the time or switch sometimes between "full" and "partials" when my main goal is to build muscle.
Any explanations why one is better than other would really help and why do you think one particular way is better than other, I mean give me a a proof to back up your opinion.
