I figured I would give a little psa. Something I learned in my strength training journey. Never round your back when squatting. A lot of people know this, as well as myself, but I still do it.
To avoid this remember to always keep your spine neutrally aligned to slightly arched. Rounding can place a lot of pressure on your disk, if not careful you can injure yourself.
Just because you’re using a machine (such as myself with the smith machine above) don’t think you can’t hurt yourself.
