If you spend any amount of time inside a mainstream gym, you’ll see lots of people pushing around light weights. Not just light weights for you (let’s face it everyone has to start somewhere, don’t they?), but light weights for THEM.
This isn’t how you build a spartan body. In fact that’s not how you really efficiently build anyone up to being fit, aside from the very few who are blessed with miracle genetics.
With strength comes function, health and a fine physique. A physique that’s both “show” and “go.” New school bodybuilding brings with it many faulty ideas and methods you are much better doing without. Hopefully, your head isn’t too full of them.
