I'm trying to get more serious about working out instead of just going once a week or so. I'm trying a 90 day challenge and I'm trying to push myself everyday. Here's me squatting 90lbs on the smith machine:

Not bad. You can go a little deeper on the squats (thighs parallel to the floor), and I'd recommend using a free barbell (no smith machine).
