Any and all exercise is good for the body. Hiking, running and bicycling were favorite activities of my family. My ability to run long distances is what got me through Basic training in the US Army. My inability to do push ups and any activity that involved upper body strength was seen by the Army instructors as a reason why I shouldn't pass Basic training but beating my Drill Sergeants in a long distance race changed their minds. No matter how many weights I lifted nor how many protein shakes I drank, I couldn't ever grow any arm muscles.
