Is there a fitness facility in Downtown Cincinnati?

You can also go to the Gym at Carew Tower. They are open seven days a week and offer classes and personal training. They also have a pool. They are a great option for Downtown workers, but they tend to get very busy during lunchtime.

YMCA and YWCA both have locations in Downtown Cincinnati. In addition to fitness facilities including a gym and swimming pool, both provide child care, fitness classes, development programs and camps for children. In addition, the YMCA offers personal trainers.
If you're looking for something a little different, check out the Cincinnati Snap Fitness Center (http://www.snapfitness.com/cincinnati) located on 7th & Vine, which offers great cardio and exercise equipment as well as wellness programs and personal trainers. In my opinion, membership rates at Snap Fitness are affordable as well.
