Thanks, George. I had been doing a combination of weights and cardio, with inconclusive results (as a newbie, I'd been losing too fast to really track), but we had a sub in my favorite class at the gym on Monday, and it's Thursday, and I'm STILL hurting! I think this chick may be my key! I am down 1% BF this week--it was instantaneous! It's taken almost 3 months for 7%, and then in 1 hour, I'm down 1 more %! I am shocked at how much more toned my thighs are after only one class with her. I agree that weights are critical. Maybe I just need to push myself more. I had also heard that smaller weights, more reps was ideal. Any thoughts on this?
