First, you should get a smile and a warm welcome when you walk in! Go a little early to avoid the line up. The registration process for new members takes a little longer then your weekly weigh-ins will. You'll be asked whether you want to pay weekly, buy a 20wk savings plan or purchase a Monthly Pass. Monthly Pass is really the best deal. You'll get free e-tools and possibly avoid paying the registration fee. I'm saying 'possibly' because I dont know where you live -- in Canada, registration is free if you purchase Monthly Pass.
You'll have to fill out a registration form. They should ask you if you were ever a Lifttime member because that's a different form. They'll ask you to get on the scale and your weight will be recorded in the Pocket Guide which they will give to you along with some other information. The Pocket Guide is something you need to bring with you each week.
The meetings usually last about 30-40 minutes and afterwards, new members remain behind for a 20 minute program knowledge session. All of the weekly meetings have a different topic, the leaders are usually knowledgeable and upbeat and the meetings are always interesting and fun. Most of them start off with celebrations where the members (if they want to) will let everyone know how much they lost.
The meetings are a great place to get support, tips and get to know people.
Now having said all that, the program is changing in the US next Sunday. (If you're in Canada, it's changing the following week.) If you want to join this Friday and follow the current plan for the weekend, then please do. However, if you can wait until next week, you may want to consider that. The fees are not going to change, just the weight loss plan.
Let us know what you decide and good luck on your weight loss journey!
