Some people think that Chris Christie is much too out of shape to effectively hold office...

65. He has a bit of a bay window, but he looks like he's got a goodly amount of muscle.

He golfed--enjoyed it a great deal too, apparently--and that was before golf carts:

The American Golfer
August 1911

President Taft says: "My advice to the middle-aged and older men, who have never played golf, is to take it up. It will be a rest and recreation from business cares, out of which they will get an immense amount of pleasure, and at the same time increase their physical vigor and capacity for work, as well as improve their health. This applies particularly to the government clerks, and I sincerely hope that the proposed public golf course will soon be opened, and that men and women of sedentary habits here will be enabled to get this splendid form of exercise."

The American Golfer
April 1913
On PUBLIC GOLF

Ex-President Taft has gone on record strongly in favor of golf, his favorite recreation, when he embodied his views in a recent letter to the Chamber of Commerce approving the establishment of a public golf links in the parks of Washington, D. C. "You know my tendency to golf, my sympathy with anybody who wants to play it, and my desire to spread a love for the game whenever I can. Golf is a splendid recreation which can be enjoyed with profit by the young and the old. It is in the interest of good health and good manners. It promotes self-restraint, and, as one of its devotees has well said, affords a chance to play the man and act the gentleman. It is the game of all classes, not a mere plaything for faddists, nor, as many suppose, a game for the rich man only. FAVORS FREER USE OF PARKS. "I favor a freer use of public parks by the people than we have had in the past. They should be available for tennis, baseball, skating, golf, and like games, under reasonable restrictions. Golf is the least injurious of outdoor games to the landscape features of our public parks. "I think all our parks should be opened for golf unless there is some specific objection in public needs. The use to which they are put should not be confined to driveways, which are a boon to those who own carriages and motors, but should include healthgiving games for the enjoyment of those who cannot afford to develop country clubs."
