Personally I do walking but I am not regular on it. Even my mom and dad wants to go for walking but some how all feels lazy for going out for walk. Going out is not that easy with all traffic. We can wake up early to avoid traffic but waking up early everyday is quite hard for me. So I am thinking to purchase tread mill for home so that everyone can give time for walk. Do you think it is worthy to buy one? What you guys say?
