One thing I've noticed while browsing this forum are that there are a lot of you that complain that you're not lifting the weight you feel you should be, or want to be. It seems the people that should be more concerned with this are powerlifters, not body builders. Why?
What's key when it comes to gaining the mass so many of us strive for? Yes, nutrition probably pops into mind. But think about it in terms of your work out. Finding the right exercises coupled with our bodies ideal number of sets and reps. And when it comes down to it, finding the proper resistance is really a huge key. Does your body know if you're using 60 lb DB's instead of the 80 lb DB's you wish you were using? Nope. All your body know's is that there's a certain amount of resistance being applied. Those numbers on the sides of the plates and DB's are there as a means to measure your progress.
Why do I bring this up? Think about how many people have horrible form in an effort to lift more weight. They sacrifice applying proper resistance in a controlled manner just to look good or be able to tell others they curled 100 lbs or more last night. And even those who are more concerned about building up their body over looking good in the gym still fall snare to the same jerking movements and improper form because they feel they should be lifting more weight. And that's really a step back.
Getting the right resistance is the key.
I thought these few points might serve as a good reminder for those that complain about what they're lifting or feel they should be able to lift more. When it comes down to it, if you're getting the physical results that you're shooting for, then how much you're lifting is just side note to accomplishing your goals of getting big.
