When Should I workout

If you feel your treadmill machine is apparently going uphill every day and downhill at night, or you run much faster in the evening than at lunch break. So, don’t worry – you’re not the only one. In 40 interviews with athletes, from ordinary club plodders to Commonwealth Games 1500m winner Michael, everyone said to run far better at some point of the day as compared to another. Many had actually decided to put this to the examination.
