Most bodybuilders lift way too heavy for OPTIMAL MUSCLE GROWTH! I see it everyday! Bodybuilders are NOT powerlifters, and although there is indeed a direct correlation between strength and muscle mass, you still need to be able perform the proper amount of REPETITIONS!
It’s NOT about how strong you are; it’s about how strong you are IN THE 8-12 REP RANGE! It doesn’t matter how much weight you can do 3 times! Listen, if you need a SPOT just for a “lift-off”, chances are you are too heavy(there are exceptions). If you can only do 3, 4, or even just 5 reps, YOU ARE GOING TOO HEAVY! Trust me, you will grow MUCH BETTER from a SOLID, CLEAN 8-12 repetitions than you will from a SLOPPY 4-6. Heck, even a perfect 4-6 will not build as much muscle as 8-12, but going very heavy occasionally does have it’s benefits as well. For instace, the stronger you are, the more weight you can do in the 8-12 rep rage!
Give it a try, I guarantee you wiill realize that you’ve been lifting too heavy and it is actually holding you back. So, take all of that STRENGTH that you have built-up, and start REPPING THAT SHIT OUT!! LOTS OF SETS TOO! At least 15-20 for all muscles!
