I was a member of Som Sports Complex since last year.
For the gym I can not say much as I enrolled only for the swimming.
I must say it is the one and only swimming pool in rohini which is well maintained and nicely done.
The one thing I liked about the pool is that it has the size/area/measurements as of a full sized olympics pool.
One lap of it and u are exhausted.
They have great trainers and adjustable swimming timings as per your busy schedule.
