Most people who join a gym never reach their goals. That is not an opinion. That is what the data shows. And one of the biggest reasons is that they train alone, without any real structure or accountability.
So how many people actually use a personal trainer, and does it make a difference? Let me walk you through the numbers.

What percentage of people use a personal trainer?
Roughly 12 to 15 percent of gym members in the United States and Australia work with a personal trainer at any given time. A 2023 report from the International Health, Racquet and Sportsclub Association (IHRSA) put personal training usage among gym members at around 14 percent globally.
That means about 1 in 7 gym members uses a trainer. The other 6 are figuring it out on their own, and most of them are not getting the results they want.
When you zoom out to the general population, the number drops further. Only around 6 to 8 percent of adults who exercise regularly work with a certified personal trainer. Most people who exercise do it without any professional guidance at all.
How many people hire personal trainers each year?
The personal training industry in the US alone generates over 14 billion dollars per year, according to IBISWorld. In Australia, the fitness industry brings in around 3.5 billion dollars annually, with personal training making up a significant portion of that.
Globally, an estimated 300,000 to 400,000 certified personal trainers are working with clients right now. The demand has grown steadily since 2010, with a sharp spike after 2020 as people shifted toward one-on-one and online training.
The Bureau of Labor Statistics projects fitness trainer employment to grow 14 percent through 2031, which is much faster than the average for all occupations. People are hiring trainers more than ever.
What is the average cost of a personal trainer?
In Australia, a single personal training session costs between 60 and 120 dollars on average. In major cities like Melbourne and Sydney, rates sit closer to 80 to 150 dollars per session depending on the trainer’s experience and qualifications.
In the United States, the average is 40 to 70 dollars per session, though premium trainers in cities like New York or Los Angeles charge 100 to 200 dollars per hour.
Most trainers offer package deals. A block of 10 sessions typically brings the per-session cost down by 10 to 20 percent. Monthly unlimited packages at boutique studios can run 300 to 600 dollars per month.
Online personal training is cheaper. Most online coaches charge 100 to 300 dollars per month for programming, check-ins, and support. This has made professional coaching accessible to a much wider group of people.
Are personal trainers worth it for weight loss?
Yes. The research is clear on this.
A study published in the Journal of Sports Science and Medicine found that people who trained with a personal trainer lost significantly more body fat and gained more lean muscle over 12 weeks compared to people who trained alone with the same program.
Another study from the Journal of Strength and Conditioning Research showed that supervised training produced 30 to 40 percent greater strength gains than unsupervised training, even when the program was identical. The difference was accountability and technique correction.
For weight loss specifically, the combination of structured programming, nutritional guidance, and consistent accountability is what drives results. A trainer provides all three. Most people training alone are missing at least two of them.
The American Council on Exercise reviewed multiple studies and found that clients working with personal trainers were significantly more likely to stick to their program long enough to see real results. Adherence is the biggest predictor of success in any fitness program, and trainers directly improve adherence.
What percentage of gym-goers achieve their fitness goals?
This number is uncomfortable. Research suggests that fewer than 20 percent of people who join a gym achieve the specific fitness goals they set when they signed up.
A study from the University of Scranton found that only 8 percent of people successfully achieve their New Year’s resolutions, which are often fitness-related. Separate research from Strava analyzed over 800 million user-logged activities and found that most people abandon their fitness goals by the second Friday of January, a date they now call Quitter’s Day.
The dropout rate for gym memberships is high. Around 50 percent of new gym members quit within the first 6 months, according to IHRSA data. Of those who stay, many are not training with enough intensity or consistency to produce meaningful change.
People who work with a trainer show much better retention. One study found that clients with a personal trainer were 3 times more likely to still be training consistently after 6 months compared to people training alone.
How often do most people see a personal trainer?
The most common frequency is 2 to 3 sessions per week. This is what most trainers recommend for people with general fitness goals like fat loss, muscle building, or improving overall health.
A survey by the Personal Training Development Center found that 47 percent of personal training clients train with their trainer 2 times per week. Around 30 percent train 3 times per week. Only about 10 percent train once a week, and that group tends to see slower progress.
For people focused on weight loss or body composition, 3 sessions per week with a trainer, combined with 1 to 2 independent sessions, produces the best outcomes based on current research.
For general health and maintenance, 2 sessions per week is enough for most people to see consistent improvement over time.
Why do most people not use a personal trainer?
Cost is the number one reason. In surveys, around 60 percent of people who do not use a trainer cite price as the main barrier. This is a real concern, and it is worth addressing directly.
The second reason is that people do not think they need one. They believe they know enough to train on their own. The data on goal achievement suggests otherwise for most people.
The third reason is intimidation. Many people feel they need to get fit before working with a trainer, which is backwards. Trainers work with beginners all the time, and that is often where the impact is greatest.
Who benefits most from working with a personal trainer?
Based on the research and what we know about behavior change, these groups see the biggest return from working with a trainer.
- Beginners who have never trained consistently before. Learning correct technique from the start prevents injury and builds a foundation that compounds over years.
- People who have plateaued after months or years of training alone. A fresh set of eyes and a structured program breaks through stagnation fast.
- People with specific goals like preparing for an event, losing a set amount of weight, or recovering from injury. Specific goals need specific programming.
- People with low accountability who know they will skip sessions if no one is waiting for them. The financial and social commitment of a trainer appointment is a powerful motivator.
- People over 40 who need to train smarter to manage recovery, hormonal changes, and injury risk. A good trainer adjusts programming based on these factors.
What does the research say about long-term results with a trainer?
A 2014 meta-analysis published in the Journal of Sports Sciences reviewed 10 studies comparing supervised and unsupervised exercise. Supervised training produced consistently better outcomes across strength, endurance, and body composition measures.
A longer-term study following clients over 24 weeks found that people with trainers maintained their results better after the program ended. They had built better habits, understood their training, and had more confidence in the gym.
This is the real value of a trainer over time. It is not just the sessions. It is the education, the habit formation, and the shift in how you think about training. That carries forward long after the formal coaching relationship ends.
Frequently Asked Questions
Is it worth getting a personal trainer if you already know how to exercise?
Yes. Knowing how to exercise and training optimally are different things. Most experienced gym-goers have blind spots in their programming, technique, or recovery. A trainer identifies and fixes those gaps. The research on supervised versus unsupervised training shows better results even in experienced exercisers.
How long does it take to see results with a personal trainer?
Most people notice measurable changes in strength and energy within 4 to 6 weeks. Visible body composition changes typically take 8 to 12 weeks of consistent training and nutrition. The timeline depends on training frequency, diet, sleep, and starting point.
Can you get results without a personal trainer?
Yes. People get results training alone. But the data shows it takes longer, dropout rates are higher, and the risk of injury from poor technique is greater. A trainer accelerates the process and reduces the risk of wasted time and effort.
What should I look for in a personal trainer?
Look for a nationally recognized certification such as NASM, ACE, CSCS, or in Australia, a Certificate IV in Fitness at minimum. Experience with clients who have similar goals to yours matters. Communication style matters too. You need someone who explains the why behind what you are doing, not just someone who counts reps.
Is online personal training as effective as in-person training?
For people who already have solid technique and self-motivation, online training can be just as effective and costs significantly less. For beginners or people who need hands-on technique correction, in-person training produces better early results. Many people use a hybrid approach, starting in-person and transitioning to online once they have the fundamentals.
The Bottom Line
What percentage of people use a personal trainer sits at around 12 to 15 percent of gym members, and roughly 6 to 8 percent of all regular exercisers. That is a small number given how much the research supports the value of professional coaching.
The people who use trainers get stronger faster, lose more fat, stick to their programs longer, and are far more likely to actually reach the goals they set. The cost is real, but so is the cost of years of training without results.
If you are serious about your fitness goals, working with a qualified trainer is one of the highest-return investments you can make in your health.
