Backswing speed: the first move decides the whole swing
Most tempo problems are born in the first move away from the ball — long before anything visible goes wrong. This is the metric that catches them at the source.
Backswing speed is the speed your hands move at from takeaway to the top, measured across the whole movement and not as a single value. What matters is where the speed peaks: around the middle of the backswing is healthy, far too early is a snatched start, far too late is a swing that never got going.
Why backswing speed matters
The way you start the club back sets the rhythm of the whole swing — most tempo problems are born in the first move away from the ball. A snatched start leads to a violent move at the top: the body falls out of sequence and you come over the top — slices and pulls, for a right-handed player. Start it low and slow, and let the speed build.
This is the metric that ties together two things golfers usually treat separately. A slice is diagnosed as a path problem, and it is — but the path went wrong because the transition was rushed, and the transition was rushed because the start was too. Fixing the last link in that chain is far harder than fixing the first.
- The curve — your hand speed, traced from takeaway to the top.
- The zone — where the curve of a 3:1 backswing sits. Yours should climb into it and stay there, instead of spiking through it early or only reaching it at the top.
- The peak — the moment of maximum speed, as a fraction of the backswing.
The backswing speed numbers
The useful number here is not a speed. It is a moment — when, in the backswing, your hands were moving fastest.
When you tell a golfer to start slowly, most of them slow the entire backswing down and arrive at the top with nothing built — and then rush the transition to compensate, which is exactly the fault they were trying to avoid. The goal is not a slow backswing. It is a backswing that accelerates, peaking somewhere in the middle, so the club reaches the top already moving.
How to measure your backswing speed with a phone
Backswing speed can be measured from either angle, because it tracks the hands through time rather than through space. Down the line is the more useful of the two, because it lets the same video produce your plane numbers as well.
You put the phone down, step up to the ball and set the club behind it. Club detection recognises the clubhead at address and starts recording on its own; when the swing is over, it stops and analyses. Nobody has to stand behind the camera.
The drill
If your peak arrives too early, this is the drill for it. Note that it does not train slowness: it trains a backswing that accelerates. The ratio is what you work on with the metronome beat.
Three counts to the top
Count "one" with the shaft parallel to the ground, "two" with your lead arm parallel to the ground, "three" at the top. 10 swings counting out loud, then 5 in silence.
Each count shorter than the last. The backswing accelerates.
This is not about going back slowly. An evenly slow backswing arrives at the top with nothing built, and the transition pays for it.
Frequently asked questions about backswing speed
What causes an over-the-top move?
Often a rushed takeaway. Snatching the club back leaves the body out of sequence at the top, and the recovery is to throw the arms out from there — which is the over-the-top move that produces slices and pulls.
Should the backswing be slow?
It should accelerate, not drag. An evenly slow backswing reaches the top with no momentum at all, which usually triggers a rushed transition. Hand speed peaking around the middle, between 40 and 65 per cent of the way, is the healthy pattern.
How does backswing speed relate to tempo?
Tempo is the ratio between the two halves; backswing speed describes the shape of one of them. You can hold a 3:1 ratio with a badly shaped backswing, which is why the app reports both.
Will slowing my backswing cost me distance?
No. Clubhead speed is generated on the way down, and downswing duration barely varies between players. Lengthening the backswing changes the ratio without touching the half where the speed is made.
How do I measure my backswing speed?
Golfective tracks your hands through the backswing from a phone video and plots the speed curve, marking where it peaked and comparing the shape against the ideal tempo zone.
