I don't know where the 10,000 daily steps figure comes from, but moving around more than two hours daily seems like a fairly reasonable thing to do in order to remain healthy. Or maybe run for 45 minutes, or walk to work, or go swimming or do a ton of other physical activities I am not going to bother listing. Personally I ride mountain bikes in every way possible, and time permitting also as often as possible.
