There are gyms and a variety of sports available (volleyball, rugby, soccer, basketball, tennis, etc). There's even Lao baseball. If you look hard enough, I think you'll find it. Not too expensive as a general rule. - Oct 2018
There is a gym at Sengdara that many expats used. There was also a gym called BeBe (?) that opened. We used the Embassy gym, so I am not sure how much it costs. I think it was around US$300 for a year at Sengdara when we arrived. - Jan 2014
