Answer: B and D. Any physical activity is beneficial.
The Physical Activity Guidelines recommend that most adults need 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity each week.
Autumn is a wonderful time for you to safely enjoy the outdoors and get some exercise with family and friends. It's a great season for picking apples and pumpkins, going for a hike, or biking. Be sure to bring appropriate clothing and protective gear like sturdy, comfortable shoes for hiking and helmets for biking.
If you are having a picnic, always pack plenty of clean water and healthy snacks. Pick healthy choices like seasonal fruits and vegetables such as apples, figs, and persimmons. Separate raw and cooked food and keep food in waterproof containers stored at the proper temperature. Go outside and enjoy the fall weather!
