Travel can take a toll on you mentally and physically, especially when you skip out on your normal exercise routine. If your hotel doesn't have a gym, these simple exercises require no equipment, and are quiet enough to do in any hotel room.
The graphic below, from Swissôtel and Judit Rango of lovefitnessonline.com, covers nine different exercises that cover flexibility, core strength training, and even some cardio. No weights, steps, or other equipment is necessary, so now you have no excuse for skipping out on your workout. Furthermore, these workouts are fairly quiet, so you don't have to worry about disrupting the folks renting a room near you. Lay out an extra hotel towel and get at it. All in all, they won't take you more than 20 minutes.
