I just finished up a 5:30am cardio class online with cardio and strength work. I really thought I'd be a miserable failure, and hate the idea of more online time in front of a screen. But it wasn't half bad. I could modify the exercise to meet my fitness level (and save my knees). But it still pushed me.
I was getting increasingly concerned about fitness as the weather gets colder and the days get shorter. So this is a good solution for me. Just putting it out there if anyone else was like me and reluctant to try something like this.
