All Diets Work, That's the Problem!. Jen Sr. Brewer
Aerobic exercise is anything that is continuous in nature and consists of moving the same muscle groups for a prolonged period of time (at least 10 minutes). Examples of aerobic exercise include walking, jogging, swimming, and biking.
Anaerobic exercise (resistance or strength training) uses the muscles to work against a resistive load (usually weights, bands, medicine balls, etc.).
The body needs both forms of exercise throughout the week. The current recommendations say that we should aim for at least 60 minutes of exercise every day of the week. Of those bouts of exercise, two to three sessions should be resistance training (preferably alternating the days with cardio), and the rest should be aerobic activity. With resistance training, it’s best to lift muscle groups that oppose each other in the same session. For example biceps (front of upper arms) and triceps (back of upper arms), pectoralis (chest) and trapezius (upper back), deltoids (shoulders) and latissimus dorsi (lats) (middle back), abductors and adductors (inner and outer thighs), and quadriceps (front of leg) and hamstrings (back of leg).
One of the biggest complaints I receive from patients regarding exercise is, “I don’t have time to exercise.” And they are right. We don’t have time to exercise. We have to make time to exercise. If you can’t find a continuous 60 minutes, you can exercise in smaller sessions throughout the day, provided those sessions increase the heart rate enough to give one the benefits of exercise. In studies, people who exercised for ten-minute mini-sessions throughout the day saw the same benefits as those who did the full amount of exercise at once.62,63 See Tool 20: Schedule Exercise for more information on exercise.
