Moved out of Frisco about a year ago, but I thought the equipment was pretty decent. They have treadmills, ellipticals, stair climbers, exercise bikes, weight lifting machines of all kinds, yoga mats, weighted exercise balls, free weights.
Don't remember their classes but they were decent.
My family liked the water play area outside.
The FAC is a family type of Rec center kind of like the YMC but better.
