This takes focusing on your breathing to a whole new level. At the LaSource Resort and Spa in Grenada, first-time divers can overcome their fears of diving and practice meditation techniques and yoga positions, all while under water. This scuba-yoga program is taught by a group of professional divers called Aquanats, who lead Pranayama yoga poses. Pranayama yoga focuses on the science of breathing, which can help divers, swimmers, athletes, and magicians hold their breath for long periods underwater.
