 Obviously, that's a 45-minute class, but it's functional fitness that includes five phases being warm-up, learning form, the main workout, core exercises, and then the cool-down because ain't nobody got time for lactic acid settling in one place. Thank you, Swimmin' Coach Judy, for teaching me. That is one of the many reasons. A cool-down, super important after a workout. I digress. Functional fitness.
