Lag and Release
In short
Lag is the angle between your lead arm and the club shaft that you hold until shortly before impact in the downswing. The release is the moment when that angle opens around impact and the clubhead reaches the ball. Opened too early, it is called casting. Well timed, it adds speed and consistency.
Lag and release: the meaning explained
At the top of the backswing, your arm and the club form an angle. For a right-handed golfer this is the left arm, with the shaft hanging from it like a lever. When you start the downswing, this angle stays at first. The clubhead trails behind the hands. Golfers call this lag, from the English word for delay.
The release is the counterpart. Just before the ball, the angle opens, the club straightens again and the clubhead swings past the hands. The wrists relax, and the head of the club reaches its highest speed around impact.
The two terms belong together. Without lag there is nothing to release at the right moment. Without a release the clubhead would stay behind the hands and the clubface would often meet the ball open. A good swing shows a clean interplay of both phases.
How lag is created: the right order in the downswing
Many golfers try to hold the angle actively with their wrists, which often leads to tension. It is better to get the order of the movement right.
A good downswing starts from the ground up. Hips and legs move first towards the target, followed by the upper body, the arms and finally the club. This order keeps the club behind the hands at first. The angle largely creates itself, because the body rotation takes the arms along and the club follows.
The hands can stay relaxed. A soft grip makes lag easier. A tight grip often brakes the natural movement of the club. A calm change of direction at the top also helps. If you throw the arms or shoulders forward here, you lose the angle in the first few centimetres of the downswing. You can read more about this fault under the term over the top.
Casting: when the release comes too early
Casting means releasing the club too early. The angle between arm and shaft opens in the upper part of the downswing, far before the ball. The club is thrown forward like a fishing rod.
The effects are usually easy to spot:
- The lowest point of the swing often comes too early and the club hits the ground first. The result is fat shots.
- If the wrists are used actively at the last moment to find the ball, it is often struck poorly. The result is thin shots and shots without distance.
- The club has little speed left at impact. The ball flies shorter than with the same club and a clean release.
- The clubface can be open at impact, which can encourage a slice.
Casting is very common among beginners, because instinct says: I must hit the ball with the club right away. Let the body lead the club and the ball is simply picked up on the way.
Practical example: a 7-iron over 130 metres
Imagine you stand on a par-3 hole and want to hit a 7-iron 130 metres to the flag. Your backswing is good. At the top, however, you push down with your hands. The angle to the shaft opens at halfway down. The club is low early, arrives flat at the ground and hits the turf first. The ball flies only 100 metres and lands short of the green.
On the second attempt you think about the order: hips first, hands stay relaxed and follow. The shaft stays behind the hands for longer and only opens shortly before the ball. Now the club meets the ball first and the ground afterwards. The ball flies 130 metres and lands on the green.
An example like this shows why the release affects distance. The difference lies in the timing of the release and hardly at all in the effort.
Lag, release, flip and wrist action compared
The terms around the release are not used consistently. Here is the usual classification.
- Lag: the angle between lead arm and shaft in the downswing.
- Release: the intended opening of this angle around impact.
- Casting: a release that comes too early, far before the ball.
- Flip: a release in which the wrists actively flick over just before the ball to save the clubface. The club is not swung freely.
- Wrist hinge: the cocking of the wrists in the backswing, from which lag arises in the first place.
Important: the release is not a single hit with the hands. It is the result of body rotation and a relaxed grip. It flows evenly and without a spike of force in the wrists. The same goes for lag: it comes from the sequence of the movement and is not forced.
Common misunderstandings about lag and release
A number of misunderstandings persist around lag and release.
- More lag is always better: an extremely large angle does not guarantee a good shot. What matters is that the release comes at the right time. An early or late release shows in the ball flight.
- Holding the wrists in place: if you block the angle on purpose, you tense the arms and the grip. The club then cannot swing freely.
- The release is a hit: if you force it with a jerk, the club does not travel through evenly. A relaxed swing through the ball works better.
- Only important for long shots: lag and release play a smaller role in chips and pitches, but a big one in full shots with irons and woods.
- The body does not matter: without body rotation there is no clean lag. The arms alone cannot carry the movement.
A coach can see on video when in the downswing the angle opens.
Tips and drills for more lag and a better release
A few drills help you train the feel for lag and release.
- Pump drill: swing to the top, then pump down to about hip height three times and back up. On the fourth swing, go through. This shows you how the shaft stays behind the hands.
- Split-hands drill: grip the club with a small gap between your hands. This makes it easier to feel how the club swings through on its own.
- Half swings: hit lots of half swings with a 7-iron. This practises the order of the movement on a small scale.
- Soft grip: hold the club loosely enough that it would not slip out, but without pressure in the forearms.
- Video: film your swing from behind and check whether the angle is kept in the downswing.
Practise slowly. Speed comes from the sequence of the movement. It does not need extra force.
Try it at Golf Lounge
Lag and release are hard to feel but easy to measure and see. At the Golf Lounge’s TrackMan range, every shot shows values such as club head speed, launch angle, ball speed and carry. In addition there is V1 Pro video analysis. This lets you spot the effects of an early release in the ball flight and in the swing picture. The TrackMan technology runs all year round on the covered facility, whatever the weather. If you want help reading the numbers, you can also book a coaching session that uses the TrackMan data.
Frequently asked questions
What does lag mean in the golf swing?
Lag is the angle between your lead arm and the club shaft that you hold until shortly before impact in the downswing. The clubhead trails behind the hands and is only released shortly before the ball. The angle comes from the right order of movement: first the hips, then the upper body, arms and club. It should not be held in place by muscle force.
What is the release in golf?
The release is the opening of the angle between arm and shaft around impact. The clubhead swings past the hands and reaches its highest speed around impact. A good release is relaxed and even. It comes from body rotation and a soft grip and not from a jerk with the wrists.
What is casting in golf?
Casting is a release that comes too early. The angle between arm and shaft opens in the upper part of the downswing and the club is thrown forward like a fishing rod. Typical results are fat or thin shots, less distance and at times an open clubface that can encourage a slice. Casting is very common among beginners.
How do I avoid casting?
Start the downswing with the hips and let arms and club follow. Keep the grip soft and avoid pushing with the hands at the top. Drills such as the pump drill and plenty of half swings help. A video from behind shows when the angle opens. A coach can give specific tips on top of that.
