Workout locations that do NOT have Toilet facilities seem to be just buildings and/or similar constructs for self abuse.
I've been to maybe 2 "Exercise Dungeons" yet they both had operational Toiletry Facilities as well Showering Facilities in either Combined Builds or Seperate.
I'm sure there are such environs that have no plumbed Toilets/Urinals to equal a Garage setup specifically for Endurance Body Sculpting without the seeming "annoyance" of providing Bladder and/or Colon relief catch basins/buckets.
Whatever works to alleviate Swelling of Reservoir Capacities!!
