chuckystud saidThis is all about your goals. If you want to generate power in short bursts (be strong) training for muscular hypertrophy is what you do. If you want to be big and muscular, you need to train for sarcoplasmic hypertrophy. They are completely different and approached via different training paths.
You would be wise NOT to do these 5's if you are untrained. You can easily sustain a momentum injury and end up tearing a ligament or tendo. Doing this if you are untrained is ILL ADVISED.
If you do choose to do these movements, do them in proper form under full control,...otherwise...you're gonna' hurt yourself.
I checked out your profile. Impressive bodybuilding achievements! There are a number of things here I don't think I agree with, but I don't want to get into a pissing match with you on this guy's thread! Haha. I'll send you a PM.
No question, though, that any free weight lifting should be done with correct form. I wasn't implying -- I don't think anyone would imply -- that someone should start squatting or deadlifting with no clue about proper technique.
