If you’re like a lot of other people, you may get bored doing the same physical activities day after day. More than half people who start exercise training programs drop out in the first six months. So, what you do to keep your workouts fresh sometimes matters more for getting the most out of training and staying with it. For these reasons (and more), you may want to consider doing cross-training. Cross-training covers a lot of ground, including combining different types of activities (like cardio and resistance training) in one workout, doing both during the week, or including other types of training in your routine. For example, you may want to do a variety of activities on a weekly basis.
