Strength Training for Golfers: What the Evidence Supports

The short answer. Strength training is associated with real increases in clubhead speed and driving distance across the golf literature, generally in the low single digits to mid single digits as a percentage. That is worth having. What the research does not support is a guaranteed number of yards, a promise that nothing about your swing will change, or the idea that more speed automatically lowers your score. Golf performance training at Aeon is built on the qualities the evidence associates with speed, with an honest account of how much variability sits behind those averages.

What the intervention research shows

The most useful summary comes from a systematic review and meta-analysis of 20 studies. Nonspecific resistance training, meaning general strength work rather than golf-mimicking drills, was studied in 13 of them and produced an average clubhead speed increase of about 1.6% and an average hitting distance increase of about 4.8%. Combined programs, studied in seven, produced larger averages at about 4.1% clubhead speed and 5.2% distance (Brennan and colleagues, 2021).

The same review reported that the most effective formats tended to be eight-week programs incorporating golf-specific movements performed at high velocity, using roughly three to four sets of five to fifteen repetitions, while noting that adaptations varied by training type, intensity and the characteristics of the participants (Brennan and colleagues, 2021).

A second review covering 25 studies found average increases in clubhead speed, ball speed and driving distance between about 4% and 6.4% when significant findings were synthesized (Bliss and colleagues, 2020). Note the qualifier: that figure summarises the studies that found significant effects, which is a different claim from an expected effect for everyone.

An earlier systematic review of 13 studies found that all but two reported increases in clubhead speed, mostly using generic conditioning programs, and mostly in middle-aged and older male recreational golfers (Smith, Journal of Strength and Conditioning Research, 2011). The direction of the evidence has been stable for over a decade.

Which physical qualities actually track with speed

A meta-analysis of correlational studies gives a clearer view of what to train. Pooled correlations with clubhead speed were highest for upper body power, followed by lower body strength, upper body strength and lower body power. Anthropometric measures and muscular endurance were weaker, and flexibility measures showed a trivial correlation of essentially zero. Pooled correlations for squat strength, jump power and medicine ball throw fell in the moderate to strong range (Ehlert, European Journal of Sport Science, 2020).

Two cautions belong with that. First, correlation across golfers does not establish that raising a quality raises speed in an individual, which is what the intervention studies are for. Second, the flexibility result does not mean mobility is useless, since most of the programs that improved clubhead speed in the earlier review included a flexibility component (Smith, 2011).

Rotational power and the ground

Golf is a rotational sport played from the ground up, and the force question is not only about how much.

A review of ground reaction forces in the golf swing covering 24 studies found that higher vertical ground reaction force appears to benefit proximal-to-distal sequencing and energy transfer through the swing, while making the point that effective use of ground reaction force depends on timing and not solely on magnitude (review of ground reaction forces in golf, 2025).

That review also illustrates how thin some of this literature is. Of the 24 studies, ten were correlational and 14 cross-sectional, and four had fewer than ten participants. One acute study using wearable resistance in five skilled female golfers reported a 3.5% increase in clubhead speed alongside an 11.4% increase in lead-side vertical ground reaction force (review of ground reaction forces in golf, 2025). Five participants in an acute session is a hypothesis, not a training recommendation.

Mobility is not the same as flexibility

The distinction matters for how you spend your time. Flexibility describes how far a joint or muscle can be lengthened, usually measured passively, and that is the category that showed essentially no correlation with clubhead speed (Ehlert, European Journal of Sport Science, 2020).

Mobility, meaning usable control through a range, is better thought of as access. If you cannot get into a position, you cannot load it or sequence from it, and the sequencing point is exactly what the ground reaction force review emphasizes (review of ground reaction forces in golf, 2025). Passive range on its own does not produce speed, and training only for range is unlikely to be the missing piece.

Grip strength and sequencing, carefully

Grip strength gets promoted as a golf variable, and the correlational evidence does not put it near the top. Upper body power and lower body strength carried the strongest pooled associations with clubhead speed, and general muscular endurance measures were weak (Ehlert, European Journal of Sport Science, 2020). Grip is worth having, particularly for anyone who plays a lot, without being a speed lever in its own right.

Sequencing is similar. The evidence supports the idea that force applied into the ground with the right timing helps transfer energy up the chain (review of ground reaction forces in golf, 2025). It does not support any particular drill as the way to build that timing.

How long this takes, and what progress looks like

The intervention studies that reported speed gains commonly ran around eight weeks, which is a reasonable planning horizon rather than a deadline (Brennan and colleagues, 2021). Within that window the things that move first are usually strength and power measures, because those are what the training directly targets, while clubhead speed follows as a downstream effect.

That ordering is worth knowing because it tells you what to measure. If squat strength, jump output and medicine ball throw are improving, you are moving the qualities most strongly associated with clubhead speed in the correlational evidence (Ehlert, European Journal of Sport Science, 2020). If those are flat, more golf-specific drills are unlikely to rescue the block.

It also sets expectations about size. A few percent on clubhead speed is a typical average across these studies, not a floor, and reported adaptations varied with training type, intensity and who was training (Brennan and colleagues, 2021).

Speed, accuracy and score are three different outcomes

This is where most golf fitness marketing overreaches. Reviews of the intervention literature report that positive effects on accuracy or shot consistency were found in only a small minority of studies, and that effects on handicap index have been under-evaluated (Bliss and colleagues, 2020).

So the defensible statement is that training can raise speed and distance, that swing kinematics sometimes change with it, and that the link to scoring has not been established with the same confidence (Bliss and colleagues, 2020). Anyone promising strokes off your handicap is going beyond the research.

The limits of this evidence

Sample sizes are small and the populations are narrow. The earlier review drew mostly on middle-aged and older male recreational golfers with only four studies in younger skilled players (Smith, 2011). The force literature leans on cross-sectional and correlational designs with some very small samples (review of ground reaction forces in golf, 2025).

Heterogeneity is the other issue. The meta-analysis explicitly notes that adaptations differed by training type, intensity and participant characteristics (Brennan and colleagues, 2021), and the second review's headline percentages summarise studies with significant findings rather than every golfer studied (Bliss and colleagues, 2020). Averages of a few percent also mean some participants gained more and some gained little.

Finally, none of these programs were designed around your body, your history or your swing. That is the gap an assessment fills.

What this means at Aeon

We train the qualities the literature associates with speed: lower body strength, upper and lower body power, rotational force production and the ability to use the ground, alongside the mobility needed to get into positions rather than mobility for its own sake.

We also keep the promises within the evidence. Strength work is likely to help your speed and distance over a block of consistent training, changes to your swing are possible and are better managed with your swing coach in the loop, and score is a bigger conversation than clubhead speed. If that sounds like the version you want, start with golf performance training at Aeon.
