I know this is an old thread. Sorry for resurrecting it. I'm new to weight lifting and I'm finding that I sometimes can walk in there feeling sort of sore and wimpy but once I start lifting, I get this grrrrr feeling and want to lift something even heavier and any soreness or stiffness is totally gone. And today on the pullup machine it was really super hard and I went for just one more (but didn't quite make it) and once I got down off the machine I felt like I was going to cry. I hate being the only old lady in the gym. I don't think any of those beefy college guys or co-eds with their ponytails bouncing away on the cardio machines will understand.
Female, 5'3", 50, Starting weight: 163lbs. Current weight: 135 (more or less).
I can squat 192.5lbs, press 75lbs and deadlift 210lbs
