Have you ever wondered if by doing cardiovascular training and doing a strength workout on the same day, you may be compromising your strength gains or your endurance? The results of studies actually showed that performing weight training and cardio on the same day had no negative effects on endurance training, resistance training, or muscle growth. In fact, they found that doing 50 percent less of both types of exercise on the same day produced the same results as doing full workouts devoted to one or the other. So, if you’ve been doing your weight training and cardio on separate days, combine your workout to get more bang for your buck and make the SHIFT!
