For years, the default fitness client in most marketing was the same person: 20s to 30s, training for aesthetics, comfortable with high-intensity programming. That client still exists, but the industry’s fastest-growing demand is coming from somewhere else entirely.
If you’re building a client base or deciding what to specialise in next, here are the markets seeing the sharpest growth, and the opportunity each one presents.
1. Female-specific training for hormonal changes and menopause
This is arguably the biggest shift in the industry right now. For decades, exercise science treated the female body as a smaller version of the male body, and training advice followed suit. That’s changing fast, driven by growing public awareness of how hormonal changes across the menstrual cycle, perimenopause, and menopause actually affect strength, recovery, body composition, and injury risk.
Women going through perimenopause and menopause are actively searching for coaches who understand what’s happening to their bodies, rather than being handed a generic program built for a 25 year old. Strength training in particular has strong evidence behind it for this group: a systematic review of resistance training in postmenopausal women found consistent improvements in bone mineral density, muscle strength, body composition, and functional capacity (Vukotić et al., 2023).
The opportunity: demand is outpacing supply. Coaches who invest in understanding female-specific physiology, something most training courses only touch on briefly, can build a genuinely loyal client base in a category that’s only getting bigger.
2. Healthy ageing and older adults
Australia’s population is ageing. As of 30 June 2020, around 1 in 6 Australians (roughly 4.2 million people) were already aged 65 and over, and that share is projected to keep climbing, reaching an estimated 21 to 23% of the population by 2066 (AIHW data, cited in Australian Cancer Plan). Many older clients aren’t chasing aesthetics, they’re training to maintain independence: staying strong enough to get off the floor, carry groceries, or avoid a fall that changes everything. That last point isn’t just anecdotal: a major update to the Cochrane review on exercise and falls found high-certainty evidence that structured exercise reduces the rate of falls in community-dwelling older adults by around 23% (Sherrington et al., 2020).
This is a market where trust matters enormously, and where a coach who understands things like balance training, joint-friendly progressions, and how to build confidence in someone who’s afraid of getting hurt will consistently outperform a generic PT.
The opportunity: this demographic is expanding quickly, and clients tend to show strong loyalty once trust is established, making it a stable, referral-friendly base to build a business around.
3. Pre and postnatal clients
Pregnant and postpartum women are training more than ever, but the information they’re getting is wildly inconsistent, ranging from overly cautious (“don’t do anything”) to reckless (“push through it”). The evidence base has actually moved a long way here: current guidelines, including the WHO’s, support moderate-to-vigorous aerobic and resistance training throughout an uncomplicated pregnancy, with research linking regular exercise to a reduced risk of gestational diabetes, pre-eclampsia, and excessive gestational weight gain, without raising the risk of miscarriage or preterm birth (WHO 2020 guidelines, reviewed in Meyer et al., 2025). Coaches who genuinely understand safe progressions and regressions across pregnancy, and the realities of postpartum recovery including pelvic floor and core considerations, fill a real gap.
The opportunity: coaches who upskill in this area, understanding safe progressions and postpartum recovery properly, fill a genuine gap and tend to earn strong word-of-mouth referrals, since new parents talk to each other.
4. Youth athletic development
Parents are increasingly seeking structured strength and conditioning for young athletes, separate from sport-specific coaching. Done well, this builds movement competency and reduces injury risk during growth spurts. The old fear that resistance training stunts growth or damages the developing skeleton isn’t supported by the evidence: an international expert consensus statement concluded there’s a compelling body of research showing youth resistance training improves fitness, sports performance, and injury resilience when programs are age-appropriate and properly supervised (Lloyd et al., 2014). Done badly (treating teenagers like small adults), the results are far less impressive.
The opportunity: parents are actively seeking coaches who understand youth-specific programming, and it’s a category with far less competition than general adult training.
5. Corporate and workplace wellness
Employers are increasingly investing in wellness programs, partly for genuine staff wellbeing reasons and partly because healthy, engaged staff take fewer sick days. The financial case isn’t just theoretical: a widely cited meta-analysis of 36 workplace wellness studies found an average return of $3.27 in reduced healthcare costs and $2.73 in reduced absenteeism for every $1 invested (Baicker, Cutler & Song, 2010, Health Affairs). This opens a B2B income stream that’s largely separate from the usual 1:1 or group training model, think onsite sessions, wellness workshops, or ongoing contracts with a single employer.
The opportunity: it’s a B2B income stream that’s largely uncontested compared to the 1:1 market, and a single workplace contract can be worth many individual clients combined.
The common thread
Every one of these markets shares something: strong, growing demand, met by a smaller pool of genuinely well-trained coaches. That’s where the opportunity lives. A PT who invests in understanding one of these areas properly tends to build a more loyal, referral-driven client base than one competing in the most crowded segment of the market.
The industry is moving away from one-size-fits-all fitness. The coaches who grow with it are the ones who’ll be busiest in five years’ time.
