What’s your go-to “I don’t want to work out” workout?

I work out with my best friend and i record my monthly performance and changes in my body so when an old piece of clothing fits me, or when at my naked self in the mirror and see the progress i get reallly motivated , try working out for 21 days in a row if it all doesnt work out, scientific research proves that when you do a task or thing 21 days in a row it becomes a habit
