Hey Elle!
I'll just copy and paste here what I wrote in my fitness blog. I tried to explain in detail everything that we did today at the gym with the trainer. I didn't feel as challenged as I wanted to, so I added in a few more reps than he was asking for, or rode the bike longer/harder than he asked for.
10 minutes warm-up cardio (stationary bike)
Lots of different stretching (nothing I was unfamiliar with, as I still remember our stretching routine from high school soccer)
Lower and upper abdominal workout (one set, fifteen reps each)
Free weights, eight pound, bicep curl (one set, twenty reps)
Bench press machine (one set, twenty reps)
Leg press machine (one set, twenty reps)
15 minute cool down cardio (stationary bike. Stayed between 85-95 rpm for 1.5 minute intervals, then pumped it up for thirty seconds. Alternated between the two)
I also did crunches this evening after we got back from the gym. It was nice to just do them while we watched a TV show. I laid down flat on the floor, put my legs up on the couch, and then scooted in close to the couch so that my backside was touching the bottom of the couch, and my calves were resting comfortably on the cushion. Then I put my hands up beside my head (I didn’t hold on, because I was worried I would pull on my neck) and lifted my horizontal torso up toward my knees. I hope that this is correct, hehe...
Let me know if you have any questions about how we did any of it.

I think that the leg presses are definitely going to help with my thighs. You could also consider using an elliptical. As for the stomach, I'm hoping that a mix of crunches and general weight loss will help.
