What is the worst kind of golf practice? The kind that lacks a consequence or a target—in other words, one without constraints. For a story last year, the teacher Will Robins said golfers practiced smarter a generation earlier because they were limited by what they could do. “You went out to a field, and you put your umbrella out there, and you hit at that target,” Robins said. “Everything had a purpose because you’re like, ‘I have to go and pick this thing up. I have to go and find it afterwards.’ We’ve totally taken that away with the driving range.”
