You need weight training. Cardio is not enough especially when you lose weight as quickly as we do. If you are not familiar with weight machines or free weights, I would suggest a Personal Trainer. You will use the knowledge for the rest of your life. Group training is less expensive than personal training. It could cost 40 per session or cheaper in group. There are deals now because it is not the busy season yet. Look up pt training in your area online. Make sure they have the credentials. If you really want a deal, go to a local gym, get a free day pass and watch some personal trainers in action. Go approach them and talk to them. They might be independent but you have to get in the gym to talk to them. If you go to YMCA, then get a free week pass somewhere. I had personal training for a couple of months and thats all I needed to get the weight training education. Now I do it on my own. I think its a great idea for you to do it in a group!!!
