Lockdown Lethargy?

Sport England Active Lives have done a survey of 190,000 people. They report, that the first Covid-19 lockdown, resulted in an estimated (for England as a whole) 12 million people taking less than 30 minutes of exercise per week between March and May 2020 (https://www.dailymail.co.uk/news/article-8871551/Englands-Covid-19-lockdown-led-12million-adults-doing-no-exercise-poll-claims.html). One always has to be a bit careful about interpreting such results, as self-reports are a notoriously unreliable measure. Some of the respondants may not have normally engaged in exercise with or without a lockdown. Others may under or over-estimate their activity levels. Having said that, exercise is important for both physical and mental health (so a lack is serious). There was also evidence that different ethnic and socio-economic groups fared differently, depending on their circumstances (they may even misclassify exercise). I suspect that many of the respondants who would normally have taken regular exercise over this period, were people who would have used gyms or swimming pools and/or have participated in team sports. I am surprised that people did not work harder to keep gyms and swimming pools (the water is chlorinated!) accessible. It's much easier to exercise if you have a gym in your basement than if you live on the 20th floor of a high-rise. I hope that exercise will be encouraged in any subsequent curtailing of freedoms.
