I also biked to work daily before lockdown. I've been doing a "fake commute," where I get out every morning before my work day begins. Either cycling or walking.
Same here. Even walking 20 minutes every morning is nice to start a day. Now working from home requires some discipline, and I compensate it with doing a spontaneous jogging during a day.
Exercise and sunlight before work has done wonders for my mental health while working from home.
I'm lucky that the first part of my commute through green areas — I can ignore the second part through a congested part of London now that I don't have to end in the office.
I don't understand this. Why? Why couldn't you go for a 30 minutes bike ride every morning as if you were going to work? and go back home? What's the difference?
I think purpose. It's easy to take it as a perk that you can ride your bike for 30 min and get "free" exercise while you go to work. It's a bit different mindset to ride your bike just for the sake of exercising and not having a bigger goal behind it.
Can you bike to somewhere that you can work? I don't bike, but I often drive somewhere and work off my LTE connection. Got a little desk that mounts to my steering wheel and everything.
Much simpler solution as suggested by other commenters: Simply get into the habit of riding a quick 30 minute loop on the bike before working at home. Biking or running just for the sake of exercise is a completely normal thing to do and I don't see why it has to be justified by a specific purpose like commuting.
