fresno : hold on, you can do it! Try to relax : it been a rough period on the stress level, why don't you go get a massage or something, to start fresh and new? And the 20 minutes walk is a really good idea too! we're all there for you!
themilesawaygirl : reading your post, I realized I even had trouble to find the names in french LOL but I can try to describes them.
My weight program had : (they wore almost all on machines)
-some really basic leg press (3x 15-20 press)
-one that you are sitting on something (back against the chair) and you push two poles in front of you, then 9the harder part) you bring them back to you slowly, holding the weight, until your arms are at a 90 angle for your forearms (this one was KILLING me, really usefull), I think it was good for the shoulder, the arms and the back)
-you're sitting and you pull handles with weights, 3x 15-20.
- sit up, but lying on a bench, with your shoulders/neck not touching the bench
-the last one is really awkard to describe : I was lying on my stomach on the machine and my legs were one a mooving part and I had to pull my legs toward my stomach with the weight that I had choose to the mooving part... it is SO SHADY but that's the best I can describe ahaha! (this on were cool for the abs and upper legs)
I met a trainer at the gym (it was free for me too) and he built my program considering what I wanted to do and the results I wanted to obtain

I highly suggest it! (plus, he'll probably describe the machines way better that I do LOL)
