I often go swimming for about 30 minutes everyday. I think go(sửa thành going) swimming needs to be use about 300 calories. It has many benefits: it help me keep fit, make me relax(thay vào đó là 'help me have a supple body' nghĩa là giúp tôi  có cơ thể dẻo dai) and stay healthy. I go swimming with my friends. I feel go swimming is a healthy and relaxing activity . i think this habit is very good for (thêm 'your')health.
