The most important aspect that an athlete should always keep an eye on is his/her diet. Getting the proper nutrition is crucial, especially when the athlete is going though a considerable amount of training. This is because the effectiveness of any training regimen is dependent on the effort that the athlete can output, which, in turn, is determined whether or not the athlete has something in his stomach. So, for a time, I was under a semi-strict diet that only allowed me to eat certain foods on specific days. And yes, that meant no ice cream.
