What do you do when an unexpected or uncontrollable event gets in the way of your exercise plan for the day?

I try to make use of what’s in the room and do standing workouts like leg kickbacks or push-ups off of a surface and tricep dips

This hapens to me very often but i try to do the most of the task i can and then when i have a free space i double the task for example if i have 1min of streching i do 2 and i try to concentrate more in it
