Hello there! So, physical strength is all about how strong your body is. It's what lets you carry heavy things or run fast or climb up things.
Your body has muscles, which are like rubber bands that can stretch and relax. When you use your muscles, they get stronger and can do even more cool things!
You can make your muscles stronger by doing exercises like push-ups, lifting weights, or even just playing outside and running around.
But, it's important to remember that everyone's body is different, so some people might be naturally stronger than others. That's totally okay! The most important thing is to be proud of your body and take care of it by eating healthy foods and getting enough sleep.
So, to sum it up, physical strength is all about how strong your muscles are and you can make them stronger by exercising and taking care of your body!
