The Underground is Pura Vida’s small-group training studio where things get a little dirty.  Open to members and non-members alike, these are loud, intense workouts with an old-school flair. You might find yourself climbing ropes, tossing a medicine balls, or hanging from ladders, but the science behind the program and the fast results are anything but a throwback.  Visit the class schedule for details.
