Question: Can you tell me what physical activity is

Answer passage (source: WHO):
page_title: Q&A: Be Active during COVID-19
section_headers: What is physical activity?
section_content: Physical activity includes all forms of active recreation, sports
participation, cycling and walking, as well as activities you do at work and
around the home and garden. It doesn’t have to be exercise or sport – play,
dance, gardening, and even house cleaning and carrying heavy shopping is all
part of being physically active.
During the COVID-19 pandemic, when so many of us are very restricted in our
movements, it is even more important for people of all ages and abilities to
be as active as possible. Even a short break from sitting, by doing 3-5
minutes of physical movement, such as walking or stretching, will help ease
muscle strain, relieve mental tension and improve blood circulation and muscle
activity. Regular physical activity can also help to give the day a routine
and be a way of staying in contact with family and friends.

Answer passage (source: WHO):
page_title: Q&A: Be Active during COVID-19
section_headers: How much physical activity is recommended?
section_content: WHO has detailed recommendations on the amount of physical activity people of
all ages should do to benefit their health and wellbeing. (available
here for children under age
of 5 and
here
for youth, adults and olders) Here are the minimum levels we recommend:
Infants under the age of 1 year need to 


be physically active several times a day.

Children under 5 years of age 

should spend at least 180 minutes a day in physical activities, with 3-4 year-olds being moderately or vigorously active for an hour a day. 

Children and adolescents aged 5-17years ****

all children and adolescents should do at least 60 minutes a day of moderate to vigorous-intensity physical activity, including activities that strengthen muscle and bone, at least 3 days per week. ****

Adults aged over 18 years ****

should do a total of at least 150 minutes of moderate-intensity physical activity throughout the week, or at least 75 minutes of vigorous-intensity physical activity throughout the week, including muscle-strengthening activities 2 or more days per week.
older adults with poor mobility should do physical activity to enhance balance and prevent falls on 3 or more days per week. 

But any physical activity is better than none. Start with small amounts and
gradually increase duration, frequency and intensity over time.
Being active during the COVID-19 pandemic is challenging for us all. Because
the opportunities to be physically active seem to be more restricted, it is
even more important to plan in every day the ways to be active and to reduce
the time spent sitting for long periods. Put simply, it is a critical time to
ensure we all move more and sit less.

Reviewer feedback on this answer:

This is a pretty good answer. The question just wants to know what physical activity is and this response goes into the recommended amounts of it for all ages and how it can be a challenge during these COVID times.

Answer passage (source: WHO):
page_title: Q&A: Adolescents, youth and COVID-19
section_headers: I know there is a risk of getting COVID-19 at the moment, but I feel fine. Can I still play sports?
section_content: Yes. You can still play sports that are in line with the physical distancing
measures and movement restrictions that are in place in your country. Being
physically active is good for your health, both physical and mental. Set up a
regular routine to practice activities or sports that do not require close
contact with others every day for 1 hour. You can do individual sports, like
jogging, walking, dancing or yoga. There are many options to try. You can set
up playground games indoors, such as jump rope and hop-scotch, play with your
brothers and sisters, and practice some strength training activities, using
improvised weights like bottles full of water or sand. If you have access to
the internet, you can also join in online active games or fitness classes, or
set up your own online physical exercises with your friends or classmates.
Find an activity that is fun, can be done within the restrictions that are in
place in your country, and makes you feel good.

Reviewer feedback on this answer:
Gives examples of physical activities that are compatible with social distancing.
This response seems only to give examples of different types of physical activity but the question wanted the phrase defined so it could be a little better in that respect
