Working out on a regular basis means that you are achieving

Hi :)

When you exercise your body, you will feel better and happier.

You will lose weight or tone up and sweat- which is great as your body is releasing toxins
You will also become stronger.

Usually, when working out, many people feel the need to eat healthy too and that will lead to your body feeling and looking great.
Your skin will clear up and you will feel nourished.

Hope this helps :)
