I've used that last piece of equipment, that squat machine. Good God talk about designed by Satan. Burns like fuck. Awesome machine.
I will never begin a leg workout without either 1 leg or 2 leg extensions. Especially as you get older. When you get to the heavier compound movements your knees are nice and warmed up, quads are nice and tight. It helps my squat form when my quads are already pumped and tight. I also like to go the extra mile and do the dorian warm-up even prior to leg extensions: Core, leg curls, no-weight walking lunges, light weight, couple of sets each. Apparently as you get older you're more injury prone
And yes, I am an absolute nobody here. I know that. But take heed all you younger guys not warming up properly, esp rotator cuffs, core, knees, etc.
You will pay. Esp you back rounding mega show off deadlifters.
My injuries-
lower back: Deadlifting way out of my league. And what really got me, leg presses, I was going too far down which caused my lower back to round and come off the back pad. That had me bedbound for a week. That happened in 2003. And I'm still feeling it.
right rotator cuff: during the teenage/ early twenty years I would just skip the warm-up and go right to the heavy weight cuz there were chicks and bigger guys there and I couldn't be seen warming up with light weight
