Damn, that is a good deal at Gold's! I'm paying like $34/month at Mountainside Fitness, I'd love to go to the downtown Gold's but the commute wouldn't make much sense.
Nice job on the weight loss! I'm down to 175lbs myself from 195lbs earlier this year. 175lbs is my lowest since I was probably like 15 years old, I weighed around 235lbs about 10 years ago.
I just started a new strength program called Starting Strength...it's very basic but it's supposed to be really good. There is a book you can buy and also a DVD that gives you instructions on the exercises (squats, press, deadlift, bench press & power clean). Let me know if you want more info.
