Gyms for a workout? (Dakar)

We'll be arriving shortly after August 21st in Dakar and will be searching for a place to live in Plateau. Working out is part of my weekly regimen and I'm wondering what gym options exist in that neighborhood where we will likely live. I enjoy the various lifecyle type machines (stairmaster), classes like aerobic, step aerobics, body conditioning and yoga. I don't mind considering a hiring a trainer if that is an option. Any input would be great.
