Do you exercise by yourself? Or with others? What kind of exercise will you recommend when there is someone who is too busy?

When my friend is too busy or just can’t make it, remember you are doing this for yourself. Do not take your friend’s absences personal.
Honour your commitment you made to you. Do the one minute workout in the app and some stretching.

I usually exercise alone but when I’m feeling really gloomy I jog with my neighbors :)) And for second question, I think they would prefer just stretching or yoga
