I hate cold. I complain about cold even in a room temperature, 71.6 F. I give myself all sort of excuses not to exercise, including the possibility of getting injured, when outside temperature drops to around 45 F. According to John W. Castellani, an exercise physiologist at the Army Research Institute of Environmental Medicine, people actually get injured more often when exercising in the heat. In addition, we shouldn’t be afraid of induced asthma attack from being in the cold because the air will be in body temperature by the time it reaches our lungs. With my hectic schedule, I often can’t go to my gym and do my cardio workout. I toughened up and ran 8 miles this morning after my personal training session in 31 F. I felt great during and after my run. To prevent injuries, I spent 20 minutes stretching in my office. Too cold?…try another excuse, Guinea Pig.
