I've tried a few different gyms in Central Florida, including Lifestyle Family Fitness. The Y is the one place I've stuck with. I mostly use the downtown (Mills Ave) and Winter Park locations. The standard YMCA membership package gives you access to all of the locations in Central Florida.
One of the things I appreciate most about the YMCA, besides their helpful staff, is the FitLinxx system. This automatically tracks some of the weight machines and adds your workouts to your online tally. You can also log your workouts manually. Even though the design and interface of this web feature leave loads to be desired, it's been very helpful to me in staying motivated and keeping track of my workouts.
There's plenty of equipment, especially downtown, and the pools, Pilates classes, aerobics and other features pretty much justify the $57 single membership fee.
