TALKING ABOUT SPORTS AND ACTIVITIES

There are a lot of activities that I like doing in my spare time but nowadays my favourite hobby is Fitball. When I feel stressed or I have a bad day I usually go to the gym because it helps me to relax, getting into a good mood and feel feeling better.
I especially love Fitball classes because I think it´s a great way to work out every muscle in your body. The activity consists of doing exercises with a big ball which is acts as an unstable base (remove comma) that helps you to improve your balance and to strengthen your muscles.
To practise this activity you only need going to go to the gym, wearing to wear sport clothes, (add comma) and a ball. Moreover, you shouldn’t forget water because it´s really important to drink water while you are exercising. It's better if your T-shirt is made of breathable fabric like cotton, (add a comma) and it's also very useful to have a small towel to wipe away your sweat.
I love fitball, (add a comma) and I enjoy practising this sport in my free time. I would recommend it to everybody who is interested in sports to do it at least once in their life because everybody can do it, (add a comma) and it’s very fun.
Another sport that I really like but I don’t practise is tennis. I like watching a tennis match in the on TV; (remove comma, add semicolon) it´s really exciting. I'm I have been a big fan of Rafa Nadal since he began playing. (remove comma, add period) He's the best tennis player of all times time.
One activity that I've tried one or twice and but I didn´t like it at all is yoga because it’s very dull, (add comma) and I felt really bored.
And finally, a sport that I hate is football. (remove comma, add period) I started hating football a long time ago for many reasons. Football has become in just a business and many times often causes a lot of fights and problems.
