While attending daily classes may not practical, you can work out at home
by following along with Zumba videos
or DVDs. If you don't have a full hour to spare, you can break your workout into sessions of at least 10 minutes throughout the day and get the same benefits you would from a longer workout.
Interval training, which is cardiovascular exercise that alternates between periods of high- and moderate-intensity activity, helps you burn more calories than moderate-intensity activity alone.
