Video tape your form... shyt can feel smooth and good but when you actually watch it it's a different bag. I had to check myself on a few lifts... butt coming up off the bench on BB bench, not getting full ROM on my pulling motions , too much body English on some accessories etc.... check yourself before you wreck yourself
Say it again.
Folks think it's vanity to record yourself . No. ..
it's longevity.
Especially if you train alone and there's no one to tell you you're not looking the way you may think you are during your lifts.
