sports I practice sports on a regular basis between twice and four times a week in order to be in shape and in order to reduce stress. As a matter of fact I started jogging more than ten years ago during a period of heavy stress. The more I practiced sports the more I enjoyed it to the point of wanting to run a marathon and doing a triathlon. I then started to increase my training load but unfortunately I started to get injured like many of those who run too much. Indeed, before being able to run a marathon it is necessary to do at least a two months special physical preparation during which the work load is substantially increased. However running takes a great toll on the body due to the impact of the body weight on the floor. So, each time I train more I get injured and I have so far never been able, at my great dismay, to run a marathon. So I decided to change tacticts and do some swimming in order to maintain my work load and avoid the side effects of running. Since I go swimming I enjoy more and more this sport to the point that I feel more pleasure in swimming than jogging. Swimming has a deeper soothing effect so that after one hour of swimming I feel deeply relaxed. In the coming months I will onnce again enroll myself for a marathon and start a physical preparation running at least three times a week, each of the running sessions being more strenous than normal running workouts. I hope that the swimming sessions will much better enable me to withstand the running stress.
