If you have one single dumbbell (or something that weighs about the same as a dumbbell) then you have a workout! No need for fancy equipment at the gym.
Grab an empty spot on the floor, pick up your dumbbell (or something equivalent), and try the exercises shown in the video and photos shown in this post we spotted on the CNN website.
Hope this helps you find something that strengthens your body — even if your schedule is nuts or it’s hard to get away from home for a different workout.
