Am  Do I enjoy both watching and playing sports?

Yes! Definitely! Watching sports and playing sports can enjoy different kind of excitement be exciting in different ways. When you take part in sports by yourself, you can enjoy the feeling of controlling your body to do all kinds of movements and using strategies to against others. Those are all very interesting. But when you watching others playing games ，you can view them from a higher perspective to view the game as a whole, which gives you the pleasure pleasant of giving comments and analyzing the game. Also you can appreciate some difficult moves from professional players that you can’t do it. Appreciate the strength and skills that you don’t have. In a word, I enjoy both watching and playing sports.

This is really good!  Instead of the long one I rewrote, you could also say "can be enjoyed in different ways," but the way you have didn't really work.  Also, playing "by yourself" means playing alone, whereas the idea you're trying to convey is just "playing yourself" which means you're the one playing.  Let me know if you have any other questions.  Seriously, though, great work!
