I've been attending Genesis for about 3 months now. I've been a member of many gyms in the past, including Fitness First, and I think Genesis is very good.
There's plenty of good, modern equipment. I mix between weights and cardio and I've never found I had to wait long for any equipment to become available. The changerooms are spacious with plenty of secure, PIN-activated lockers. I haven't used the classrooms yet (am planning to join some RPM classes in winter) but they look well equipped.
The trainers and staff are very friendly, welcoming and attentive.
Its a popular gym and busy at 6am during weekdays. The range of Genesis Glenelg's customers is broad, ranging from young to old. I see plenty of 50+ people attending, which is good to see. I also think that if anyone felt they were overweight and felt out of place they shouldn't. This isn't a gym for posers (although there are some very fit people who attend). There are quite a few larger people who attend, and good on them for taking the first steps to improve their health!
There's plenty of parking in the top deck next to the gym, which is more than I can say for many gyms I've been to. Because the gym is located solely on the top deck of a relatively new shopping centre the gym is spacious and isn't split across multiple floors (I'm looking at you Fitness First Adelaide!)
Genesis don't have any aquatic facilities but they do have steam rooms.
If I had only one minor nit is that I wish they had a stretching cage and a bit more space dedicated to stretch out. read more
