Hi there, i would like to shate the benifits of biking, i am weighing 86 kilograms before i decided to do biking and i have hypertension hence i am taking my maintenance medicine to stabilizes my blood pressure. Riding a bike for the first week make a big effect on my weight from 86 before I bike to 84.6 kilos after one week, and I started to feel that my body is feeling well and doing good. Each and every ride and every sweat are good for your whole body, it is not just for cardio, it is for the whole body, stamina, breathing and releasing of all the toxic from your body via sweat glands.
