As a rowhouse instructor, I have my own perspective on the points brought up in this article https://www.vox.com/21515865/group-fitness-outdoor-workouts-online.
I have been coaching four classes a week, two indoor and two outdoor. I coach in Westport CT so we were allowed to open with studio social distancing and cleaning procedures. We also offer outdoor options via zoom for anyone to the indoor classes. The adoption of the outdoor classes has been very strong. It appears that this group is more comfortable with the outdoor option, especially for first timers.
I too am concerned about the colder weather, but as a runner, I am used to working out outside in all kinds of weather. The mental health benefits of going to a group class that are pointed out in this article make sense to me. I encourage anyone to find an outdoor fitness class ( before the snow flies) and soak up all those good vibes. It will help fuel your online classes and keep you motivated.
Community is still a thing, lets try and keep it working.
