"Turn your shoulders more."
That's the speed advice most golfers get. Bigger turn, stronger core twist, more upper body.
A 2023 study checked where club speed actually comes from. Researchers tested 28 elite young golfers (14 men, 14 women) on hip strength, twisting strength, jump power and a backward overhead med ball throw β then measured driver speed by radar.
What lined up with club speed (a correlation β 1.0 means they move together every time, 0 means no link):
β’ Fast hip extension strength: 0.67 men / 0.61 women
β’ Jump power: 0.63 men / 0.75 women
β’ Backward overhead med ball throw: 0.6 for both
β’ Twisting (trunk rotation) strength: no link
The swing starts at the ground. Legs push, hips turn that push into rotation, and the arms and club ride the wave.
The honest part: small group, all young and very good players, and a correlation isn't proof of cause. They also tested slow, grinding twist strength β not fast rotational power, which other research says does matter. It just runs on your legs and hips.
My take: golfers come in wanting more turn. We do that too. But then we build the engine β trap bar deadlifts, hip thrusts, broad jumps, med ball throws backward and overhead, hard. Push the ground. Move fast. On purpose.
Stop chasing a bigger turn. Build a bigger engine.
