I don't know much but I'll try to help. I would recommend doing a workout for a certain amount of time maybe like 15 minutes. Every 15 minutes set a time for a quick break like maybe 5 minutes (So basically work out 15 minutes and take a quick break then repeat). You can also try exercising different times during the day like a bit in the morning, afternoon, and night so you don't have to do a bunch during a long period of time.
