Speed is not just about strength
In its October 6, 2026 lesson “How Mobility Matters for Clubhead Speed,” Titleist explores a less obvious contributor to swing speed: how far the hands travel during the downswing. The lesson cites biomechanist Dr. Sasho MacKenzie. In Titleist’s account of his work, average force applied along the hand path was the strongest predictor of clubhead speed among the factors studied; hand-path distance was also meaningfully associated with speed. These are reported relationships, not evidence that making every golfer’s backswing longer will automatically add distance.
What “hand path” means
Think of the route your hands take from the top of the backswing toward impact. More available travel may offer more room to apply force and build club speed. Titleist uses a rolling-chair analogy: pushing a chair over a longer distance provides more opportunity to accelerate it than trying to do so in a very short space. A golf swing, however, is not a straight push. Strike location, clubface control, delivery and movement sequence still matter.
A longer hand path is not necessarily the same as a picture-perfect, extra-long backswing. Reaching farther while losing balance, collapsing the arms or producing discomfort is not automatically a useful change.
How mobility fits in
Limited movement in the pelvis, torso or shoulders may restrict how far a golfer can turn. Some players will benefit from working on mobility with a qualified professional; others may do better by adapting their swing to the movement they comfortably possess. Titleist notes that allowing the lead heel to rise slightly in the backswing can help certain golfers turn more freely. For a right-handed player the lead foot is the left; for a left-hander it is the right. This is an option, not a universal command. Do not forcibly lift the heel or compromise your footing.
A 24-ball self-check
The following is an original GOLFTWITT comparison exercise, not a scientifically validated training intervention or medical prescription. Use the same familiar club throughout, perhaps a 7-iron, on a safe range. Warm up comfortably. Stop if you experience pain.
Block A — 8 balls. Hit eight shots with your normal swing. Note launch direction, quality of strike, comfort and, if measured reliably, carry distance. Do not judge a block only by its best shot.
Block B — 8 balls. Rehearse the movement slowly without a ball. Let the lead heel lift a small, comfortable amount during the backswing if doing so feels natural and you can remain balanced. Hit eight unhurried shots. Avoid twisting farther than you can control or trying to manufacture speed with a sudden jerk.
Block A2 — 8 balls. Return to your normal setup and swing for eight more shots, recording the same observations. Returning to A can expose a short-term familiarisation effect, although it cannot eliminate fatigue or random variation.
If possible, film a few rehearsals from face-on and down-the-line with a stable phone positioned safely outside the hitting area. Watch balance, range of movement and strike rather than copying a tour golfer’s pose.
Read the results, not just the feeling
If block B feels freer but produces poorer contact or direction, that is not a straightforward win. Similar results across all three blocks mean the small test found no convincing difference. If a variation feels consistently more comfortable without compromising strike quality, discuss it with a coach. Twenty-four balls cannot establish that speed or distance has improved: repeated sessions and reliable, comparable measurements would be needed.
What the source does and does not prove
Titleist presents a useful biomechanical teaching concept, but its page does not supply the full experimental protocol, sample details or exact coefficients behind the research summary. We therefore make no numerical performance claims or blanket mobility prescriptions. Persistent discomfort or prior injury calls for qualified individual assessment.
