"It's only 40 minutes" is the motto at this gem. Each person has a "fitwall" which is their special "wall" equipment. The instructor will direct you to jump, squat, do push ups, plank, pull resistance bands, and just about everything that will have your whole body sore for the next two days. But remember, it's only 40 minutes...
