I am flattered you PM'd me to ask my opinion. I FR'd you with no response so I am going to Forum with my experience. Hope this provides more insight and information for us long haul Bro's and Sisters.

1 Those of us that have been around a while may know from experience or just been fortunate to hear(instead of the dreaded experience): "drying" and or "hardending" compounds take a toll on your joints. As an example my strength goes through the roof with wild aggression resulting in heavier weights while leaning out and yes: literally drying out! That water is pulled from everywhere including your joints. (Imagine running your engine low on oil).

2 Poor form is going to do in a bad way for sure! Getting out of form contorting into a position favoring your weak points and stressing your strong points as your joints suffer: not good EVER!

3 Here is a less obvious catch 22: Machines! We love to pull a pin, peg the stack and go. All the time wasted loading bars and racking bells . . . all that time may save your ass! I love machines but at 48 years old and in the gym longer then some have been sucking air I can feel my joints being worked against the machine. You are locked in and that machine will out last even a stainless steel hip replacement.

So too much weight on a machine while cutting is the worst thing(s) I can think of.

Free weights and cables! Use the cables that allow adjustment of the pulley vertically to work slightly different angles every set. Remember it's that "locked in" movement wearing your joint in one spot that causes long term shit you don't want(take it from me). Free bar that shit in GREAT form! Move those bells like you mean it. Jerking and cheating isn't even allowed in power lifting so WTF do you think you're gaining. I wrote a piece on Gay Weights but my skinny ass looks like I can move a 500lbs in any direction.

I am up for anything I missed or just don't know. Please add to this or PM me. I love this shit and love this sport!
