My best friend and I have been training to run a mud obstacle course. It’s a fitness run sponsored by our local gym. The mud obstacle course is an all-day event, and the winner receives a free gym membership. My best friend and I have a strict regimen that we follow every time that we are at the gym. Usually we go to the gym after work on Tuesdays, Thursdays, and Saturday mornings. We always run 5 miles on the treadmill, and work on legs or arms. We spend about 90 minutes at the gym during each session. Lately, the gym has been really busy. A lot of people are training for the mud obstacle course, and the gym is constantly packed. I really don’t like waiting for machines, and the indoor air quality is really suffering. The air conditioning equipment doesn’t seem to keep the whole place very cold. Not only that, but the indoor air smells like body odor. The gym has shower facilities and a locker room. There is no reason that the place should smell like a locker room. There are more than fifty or sixty air vents located throughout the building and all of the workout rooms. Even when my best friend and I have finished our work out, we still don’t smell as bad as the gym. The indoor air quality has suffered immensely, but I hope things will go back to normal after the race has been finished. This gym is close to work, but I’ll go somewhere else if the indoor air quality doesn’t improve.
