I for some reason read that as "100m shouting range" I now have an image of several members, doing their best KIAI or just random screams to a brick wall....100m away.
We could lease the range for Kiai/Chi ball masters to practice. Which reminds me - we'd need a viewing gallery and on-site popcorn vendor so we could mock said Chi masters.
Female changing rooms that aren't just a cupboard at the back of the gym! Lockers that can fit all your stuff in them - not like the ones in most gyms that you struggle to get your bag into! A dedicated section for conditioning work - sprints, prowler pushes, sled drags, Farmers walks etc (and the prowlers and sleds etc). A bouldering wall (great for grip strength).
