I recently switched to Miracle/KG gym above the trustmart on yihuan lu. It’s decent and in the mornings not too busy. The thing i like is that they have a smaller room at the back, which is usually empty, but has all the essential stuff, so often i treat it as my private gym. One gripe, like alot of the gyms are the placement of the mirrors. For some stuff you absolutely need floor to ceiling (such as when i’m doing the plank) to check for straight or arched back. That’s kinda frustrating. If you live in Tongzilin that should be within 10 mins by bike. They have a small sauna which is often closed, but they have opened it for me when i’ve asked. Dude, if you bargain hard you can get crazy discounts. Bargaining was more exhausting than my workout….
