It is not recommended to do fitness exercises during these two hours at noon. After lunch, you can stand 15 minutes, and then take a nap for 20 minutes, which is generally enough, but don't choose to do fitness at noon, and adjust the time after dinner, because your muscles are in a state of fatigue after a busy morning. If you exercise again, it will be counterproductive. The best exercise time is from 3 pm to 8 pm.
