I'm sure you've seen him before, but he often disappears (you'll learn why in a sec)...
He likes to lift heavy things and do the big compound movements like Bench Press, Deadlifts and Squats.
I typically notice him when he Squats, because he'll walk up to the rack, get under an empty bar and do 3 or 4 half-range reps.
Then, he'll load up more weight than it looks like he's capable of lifting and proceed to do a few sets, usually with horrible form.
Now, I'm making assumptions here, but I think the reason why he often disappears is because he hurts himself with his grossly inadequate warmup routine.
The thing is, he probably gets away with it... when he's younger.
But once the years start adding up, the body needs more intelligent care and jumping into a heavy lift with a single warmup set (and sometimes without!) is just asking for trouble.
So, DON'T BE THAT GUY.
You're smarter than this!
And I say this with confidence because you wouldn't be here otherwise.
I'm guessing you already have a warmup routine that might include some light cardio, some basic joint mobilizations and bodyweight exercises like Squats, Lunges and Pushups.
But if you want to warmup in a way that will OPTIMIZE your workout, ensuring that all muscles are firing, your joints are ready for the loads coming their way and you're at your maximum level of mobility, then here's what you need...
