Dynapenia is when your muscles become weak and it becomes hard for you to do everyday things like standing up or opening a jar. It happens when you don't use your muscles enough, especially when you get older. Just like how you have to exercise your brain to get smarter, you have to exercise your muscles to keep them strong. If you don't use them, they can get weaker and weaker over time. The good news is that you can prevent dynapenia by making sure you exercise your muscles regularly. This can include things like going for a walk or doing exercises like squats or push-ups. Fun activities like riding a bike or playing a sport can also help keep your muscles strong. So, remember to keep moving and using your muscles to prevent dynapenia!
