What Am I Supposed To Do About My Legs?

Remember that scene in Who Framed Roger Rabbit when Judge Doom gets steamrolled, and they find out he's a 'toon? He's trying to stand up and walk, but he's all wobbly and can't get his balance.
Well, that's what I feel like today ... only a lot worse.
A few weeks ago, I went to take a yoga class at New York Sports Club and the teacher was a few minutes late. A NYSC employee came into the class, took our information and we would all receive a free session with a personal trainer as an apology.
Last night was the session. I met with the trainer right after work, wearing a shirt I got after participating in a 4-mile running race to let him know I was a serious athlete.
We talked for a few minutes about eating habits, drinking habits, his successes and failures as well as mine. I refused to get on the scale, but agreed to do the body fat/BMI calculation. The good news: I'm about average. The bad news: The session didn't end there.
He started me out with jumping jacks, resting (and by resting, he meant running in place), doing high knee kicks, "resting", jumping in place, etc. I was winded, but I felt pretty good. Then, he had me do at least 50 squats which was a poor decision on his part.
After the squats, I had to do reverse squats - starting out on the floor and standing up over and over and ... I started to get that familiar feeling I had two summers ago on that hot subway platform. I thought I was going to faint again or vomit.
NYSC also made an ill-informed decision to use a polka-dot pattern on their floor which subsequently was creating one of those 3D images - only, I couldn't see the sailboat, I just saw the floor coming to meet my face.
I didn't think the trainer could do much damage in an hour session, so I didn't plan ahead and bring a rubber band to pull my hair back. I just had my usual hairstyle of pieces of hair pinned everywhere with bobby pins. By the end of the session there were bobby pins strewn EVERYWHERE. But, we weren't done yet.
After lifting weights for 30 minutes (!!), he gave me my evaluation (yikes), what I need to work on (everything) and asked if I wanted to sign up to meet with him again (no way). He was really nice, and completely understood that financially I couldn't do it and said if he saw me at the gym again he'd work out with me, which was kind - even if it was a total lie.
The worst part of the night, though, was getting home. Walking up and down stairs for the subway, standing for more than 2 minutes and having the energy to make a healthy dinner. Also, I bought some hand soap last week that for some reason smells like tequila. We all know my history with the drink, so smelling that after almost vomiting on my trainer was enough to send me to bed early.
