Stretch for 15 minutes after running, or your legs will grow muscles and it will be difficult to lose them. You can't sit down until 30 minutes after running. If you sit down immediately, your ass will be flat and drooping, and you will stop eating just after running. I usually run at night, so I won't eat. Morning running should be another matter. If you decide to start running, it will last forever. People who suddenly stop running will suddenly gain weight. And the muscles are long, depending on some people who learned to dance when they were young, but they didn't learn when they grew up, but there are exceptions, and they can also jog during menstruation.
