Uptown's Y! Resting in the Wells Fargo tower, you'll find this older, but newly remodeled, modest YMCA.
The staff here is super friendly. Much of the equipment is new. The lap-pool and lorckerrooms were recently updated. They offer numerous group exercise options, etc. There is a walking/running track that hovers above the center court on a secret second level. In addition to the track you'll find an area for cycling classes, more workout equipment, etc. Within the lorckerrooms are saunas and steam rooms as well.
Parking is in the deck off of MLK. Be sure to take your ticket up to the front desk and scan if for validation to avoid being charged upon exit. Just keep in mind that the validation is only good for 2 1/2 hours. The orange and green levels of the parking deck are designated for Y visitors.
Guests of the Marriott also have access to the Y since the hotel doesn't have a fitness center of its own.
Check it out if you're ever in need of an Uptown workout. It's a great spot before or after work for persons that commute to the area daily.
