Twin Cities Lifetime Fitness Workout / Walking Buddies?

Hi! My name is Amy and I'm 41 years old. I have a great deal of weight to lose (at least 100 pounds) and I'm having trouble getting and staying motivated. I'm hoping to find workout friends who have a membership to Lifetime Fitness. I live in Saint Paul and work in Apple Valley, but I'm willing to meet at any of the gyms in the Twin Cities area if it means I have someone who will help me stay accountable. -- Even if you don't have a Lifetime Fitness membership but live in Highland Park or Apple Valley and want to be walking buddies now that the weather seems to have turned for the better, please let me know!
