We were sad to learn of Jack LaLanne's passing on Jan. 23 at age 96.We thought he'd live forever. Back in 1974, Jack was gracious enough to write a fitness article for Golf Digest and pose for photos performing the exercises he prescribed for better golf. We asked Golf Digest fitness advisor Ralph Simpson, a physical therapist and athletic trainer who has worked with many professional golfers over the years, if the workout LaLanne demonstrated would still be considered great for golf. Bottom line: on whole, they're still surprisingly good. Here's a sampling of exercises from the LaLanne article and what Ralph had to say about each one.
