Michael Kim has the rare distinction of being elite at two very different skills. The first, obviously, is golf. Kim was a standout college player and won the 2018 John Deere Classic by a record eight shots. But more recently, Kim has become an elite Tweeter, giving plenty of helpful golf advice for the rest of us.

Golf Digest Senior Game Improvement Editor Luke Kerr-Dineen recently caught up with Kim, a self-described swing nerd, who explains why amateurs should chase swing speed but also be careful about copying the trendy moves of the modern golf swing.
