Weight loss for beginners - Biggest Loser

I was invited to particpate in the challenge. I understand the mini-challenges however at the risk of sounding like a total doofus...how does one pick/be assigned a team? each team works together to lose weight? Perhaps I need to watch the show once or twice to fully understand. Good luck to all!

i think it randomly put you in a team but im not sure. also may i ask where did you got your weight loss tracker?

It is an option with your signature. You just click on it.
thanx for the team info
