Beth Lewis, PhD, Director of the School of Kinesiology, recently shared her expertise with CNN Health as part of their story, How to enjoy working out if you hate exercise. “The key to maintaining exercise is to find an exercise routine that you enjoy, whether it is alone or with people; outside, at home or at a gym,” says Lewis, a professor of Behavioral Aspects of Physical Activity. “Exercise is important not only because of the many health benefits but it also improves mood, positively impacts sleep, and increases energy levels throughout the day,” adds Lewis.
