About six years ago, I decided to get fit. I decided that my first steps would be to run 30 minutes per day and to register for a 10km race (2 weeks later). The next day, after putting my sport shoes, I went out and started running. After about 30 seconds, I started to be breathless and my thighs started to hurt me so bad. I had to stop running after a minute… The next day, I decided to run 2 minutes per day instead. I did it. Two weeks later, I was running the 10km race. It was tough but I made it and something awesome happened at the arrival. Right after crossing the finish line, I stopped running and I started to feel so, so good. The (subjective) feeling was like a releasing of sweet chocolate throughout my whole body…
Such a great memory. I then started to run 10km 2 and eventually 3 times a week.
Nowadays, I exercise for 30 minutes each morning, I ran two marathons (my next one is planned for next year) and several 10&20k, I run two times a week and practice MMA three hours a week.
Take home message: It is not only about getting fit, sport makes you become a better person. Start (very) slow and stick with it no matter what.
