Because the outside air is polluted and having to wear a air filter while exercising is unpleasant. Because I have to watch out for traffic and pedestrians outside, and driving to a cycling/running path takes about 15 minutes anyway. Because looking at healthy, fit people exercising gives me more motivation to get in shape. Because I can devote more attention to my audiobooks than if I was exercising on the streets. Because the gym is in my apartment complex, so I just go downstairs and walk 2 minutes to the gym.
