Mesa AZ peeps, I need an IRL work out buddy

I have hit a bit of a slump with my weight loss, and haven't been making progress lately. I've run into this problem before (at about the same weight) and wound up going off the grid for a while.

I desperately want to avoid self sabatoging again and start working on my fitness, even if the weight stays the same a while longer. The problem is I don't currently have a gym membership, and even when I did have one I was too embarrassed to go because I didn't know what I was doing.

I'd really like to find someone nearby that's in even a vaguely similar boat so we can work out together and hold each other accountable. (And even if you're not gym equipment savvy, we can learn together!)

Here's a little info about me:

SW: 337
CW: 278
GW: 170 (for starters)
Height: 5'5"
Age: 26
I'm currently working part time and taking classes, but my schedule is pretty flexible still I'd say.

If you're interested at all, please write back and we can go over details and whatnot.
