  • CAC has been my favorite gym for about 4 years. On top of having a good range of equipment and services, the place is clean. Like really clean. It's always been clean, but they have taken a lot of extra steps to make the place safe for a 2020 world. Lots of wipes and hand sanitizer within reach everywhere. Spaces clearly marked out around benches and weights. Plastic shields between cardio equipment. Well ventilated. Big signs everywhere explaining what's safe. Again, CAC has always provided a higher level gym experience. But it's nice to see them keeping up with required changes.
