Thumbs up for aqua cycling in this short Houston Chronicle review about a Houston-based aqua cycling class. If you want to know what a class is like, this is a good first-hand account. However, the Houston class seems to only be in 4-feet of water. Most of Aquabike’s sessions are deeper, which makes for an easier workout, with more cushion to your joints.
