For the best weight loss results it’s important to cross train, i.e. alternating and combining cardio and strength workouts. Doing cardio strengthens your heart and combining exercises that strengthens your muscles increase fat burn. The body uses more calories to make and maintain muscles than it does for fat, so post strength training session will still be burning calories! For example, Sprint Intervals help you develop cardiovascular strength and the 7 Minute+ program strengthens the whole body!
