Curves was my beginner gym, and I guess I should be grateful for it. I had decided to get fit, and it was there, I would have been highly intimidated by a “real” gym, and probably couldn’t afford one.
The workouts were not challenging, it’s always the same. In theory, as you get stronger, you push the hydraulics in the machines harder, and they push back harder, but it doesn’t work that well in practice.
In addition, management/ownership of your franchise can have a major impact. I experienced no-show staff, so I’d be up early, downtown in my sweats, and no gym. In the end they closed in the dark of the night, leaving me to chase my last month’s dues.
When it vanished, I joined another women’s club, I also was, at that time more comfortable in a women’s setting.
My recommendation would be explore what you can do without equipment at home.
