Dear President,
I am a student in this university who is taking charge of Sports Association. Generally speaking, the ways that you offer to improve our physical condition are quite good; however, I have some better suggestions for you.
Firstly, it would be greatly appreciated if you could set swimming and skating as students regular exercises, because exercise is always making us more energetic. Moreover, a balanced diet and sufficient sleep are both necessary to our health. So it is advisable for you to put emphasis on developing students good habits.
I hope that you will find these suggestions helpful.
Sincerely yours,
Li Ming
