Former India captain MS Dhoni has proved that age is just a number, time and time again. Dhoni, who is not a part of the Indian cricket team currently, was spotted working out. In a video posted by a Dhoni fan account, the 38-year-old can be seen doing chin-ups. Not only does that show that he still has the power in those muscles but it could well be the reason behind Dhoni’s humungous sixes.
