Exactly! Wow, does that bring back memories -- the assisted pull up machine had a big role in the year that I was losing weight and I know you'll have fun with it too, Nelie.
I was 46 years old and had never done a pull up in my life -- I was one of the nerds dangling helplessly from the chin up bar in those hideous grade school "fitness evaluations" or whatever they were called (I called them total public humiliation

). So it was incredibly cool to actually be able to do a pull up with the assisted machine, albeit with a LOT of asistance at first. I think I started with 160# of assistance -- I wasn't nearly as strong as you, Nelie! Every day that I walked in the gym, I'd set the peg 10# lower than I had ever managed a pullup at and try to get just one. It wasn't part of my workout or anything -- it was just a little game that I played with myself. Then when I could squeeze out one at that weight, I'd drop the peg down another 10# and so on.
The combination of losing weight (less to pull up) and getting stronger made the numbers whiz by until -- ta da -- I could do ONE on my own with NO assistance. What a

thing to get so excited about, but I was floating on

.
Just keep on working on it, Nelie, just like you're doing! It's going to happen for you -- first, one with 180#, then one with 170# and then one day with no assistance at all. Count on it!
