"Efficient Fitness: The Weekend Workout Plan"

Studies suggest that working out just on the weekend can offer comparable health benefits, if you block off enough time and the exercise is intense enough. Here are five tips from exercise scientists for embarking on a weekend-exclusive exercise routine as safely and smartly as possible: prioritize resistance training, mix up upper and lower body workouts, engage in full-body cardio, don't overdo it, and don't skip warm-ups and cool-downs. Additionally, building short "movement breaks" into the day can promote strength and mobility and prepare the body for higher-intensity weekend workouts.
