20 min Fat Burning Workout for TOTAL BEGINNERS (Achievable, No Equipment)

For most healthy adults, the Department of Health and Human Services recommends these exercise guidelines
Aerobic activity. Get at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity a week, or an equal combination of moderate and vigorous aerobic activity. The guidelines suggest that you spread out this exercise during the course of a week. To provide even greater health benefit and to assist with weight loss or maintaining weight loss, at least 300 minutes a week is recommended. But even small amounts of physical activity are helpful. Being active for short periods of time throughout the day can add up to provide health benefits.
Strength training. Do strength training exercises for all major muscle groups at least two times a week. Aim to do a single set of each exercise using a weight or resistance level heavy enough to tire your muscles after about 12 to 15 repetitions.
