Gyms near Louise (Brussels)

Hello, I've just landed in Brussels and live close to the Blue Tower on Ave Louise. I'm looking for a nice gym and have visited several already, including Aspria on Louise, Fitness First on Ch. Charleroi, Golden Club on Pl. Chatelain, Health City Basic on Louise, and Silhouette on Toison d'Or. Of these only Aspria has a pool, but the downside is their very high price Protected content enrollment + over 200e per month). Are there any other gyms that I've forgotten to look at, especially ones with a pool. I prefer walking or biking distance, but if the place is good I may also take the car over there.
