What a trainer can and cannot do
The scope boundary is not a legal disclaimer bolted onto the bottom of the page. It is the most useful thing on it, because getting the order of operations wrong is how people waste a year.
Jack cannot: diagnose what is causing your pain, treat it, rehabilitate an injury, tell you whether you have a disc problem, interpret a scan, give you a prognosis, or tell you to ignore what a clinician has said.
Jack can: coach you to move well under load, build a programme that avoids positions you have been told to avoid, load the things that have been cleared, progress them sensibly, and stop when something does not behave the way training soreness behaves.
In plain terms: if nobody has assessed your back, an assessment comes first. If somebody has, and they have told you what you can and cannot do, a trainer is a genuinely useful next step — because most people leave a course of physiotherapy with a set of exercises and no idea how to progress beyond them.
That gap is where a coach earns their keep. Rehab gets you out of pain. Strength training is what makes the same episode less likely to happen again, and it is the part people almost always skip.
What “cleared by your physio” means in practice
“Cleared” is not a single yes. It is a set of specifics, and the more specific it is, the better the programme Jack can write.
Useful information looks like this:
- Which movements or positions to avoid, and whether that is temporary or permanent.
- Whether loaded spinal flexion is off the table, and whether that includes light loads.
- Whether any symptom is acceptable during exercise, and which ones are not.
- Any weight or range limits, and when they are due to be reviewed.
- What the clinician actually wants you working on.
Bring the written guidance if you have it. If all you have is a memory of a conversation from eight months ago in another country, that is worth going back and refreshing — there are physiotherapy clinics in the Pattaya area, including TARA Physical Therapy and The Physio, and your doctor can refer you.
Where a restriction and a training goal conflict, the restriction wins. Jack will not talk you out of what a clinician told you, and if he thinks the guidance needs revisiting, the person to revisit it with is the clinician.
Hips and thoracic spine: why your low back pays for them
The low back sits between two regions that are supposed to move a lot: the hips below it and the thoracic spine above it. The lumbar spine itself is built more for stability than for range.
When the hips stop rotating and extending properly, and the mid-back stops rotating and extending properly, the movement has to come from somewhere. It comes from the segment in between — repeatedly, in small amounts, thousands of times a day. That is the general model most coaches and clinicians work from, and it explains a lot about why a back that has no structural problem still aches by four in the afternoon.
So a lot of what looks like “back work” in a session is not aimed at the back at all:
- Hip extension. Sitting for years leaves hip flexors short and glutes underused. Bridges, hinges and split-stance work restore the ability to extend the hip without arching the lower back to fake it.
- Hip internal and external rotation. Limited rotation at the hip shows up as twisting at the waist.
- Thoracic extension and rotation. Reaching overhead with a locked mid-back means the lumbar spine extends instead. Getting the ribs moving usually changes overhead work immediately.
- Breathing. Unfashionable and genuinely useful. If you only breathe into your upper chest, the muscles that should be stabilising your trunk are busy helping you inhale.
Mobility work on its own is temporary. It opens a range; strength work is what keeps it. That is why a session pairs the two rather than treating stretching as the whole answer.
Loaded carries and anti-rotation, explained simply
Two categories of exercise do more for most aching backs than any amount of floor work, and neither is complicated.
Loaded carries
Pick up a weight and walk with it. Hold it in one hand and the load tries to bend you sideways; your trunk has to resist. Hold it in both and your whole midsection has to hold you upright while your legs keep moving. It is the closest thing in the gym to what the body does when you carry shopping, luggage or a toolbox — which is when backs usually complain.
Carries are easy to scale, easy to load in small increments, and they teach bracing while breathing, which crunches do not.
Anti-rotation
Instead of twisting deliberately, you resist a force that is trying to twist you. Hold a band or cable at your chest and press it straight out while it pulls you sideways; your job is to not rotate. It trains the trunk to do its actual job — stopping unwanted movement — without loading the spine into repeated end-range twisting.
Together, carries and anti-rotation build a trunk that behaves like a stable base for the hips and shoulders to work from. That is the goal. Not a six-pack, and not a stronger sit-up.
Desk and condo posture, realistically
There is no perfect posture, and the internet’s obsession with sitting up straight has not made anybody’s back better. The problem is rarely the position. It is the duration.
Pattaya has a specific version of this. Remote workers and retirees end up in condo units that were furnished for holidays rather than for eight-hour days: a glass dining table at the wrong height, a chair with no support, a laptop flat on the surface, and a sofa that becomes the office by mid-afternoon. Then the air conditioning encourages you to stay put, because outside is 34 degrees.
What actually helps, in order of impact:
- Move more often. Every half hour, stand up and do something for a minute. Anything. The best posture is the next one.
- Get the screen up to eye level. A stack of books works. Looking down for hours loads the neck and rounds the mid-back.
- Give your feet something to press into. Feet dangling means your pelvis has nothing to work against.
- Do not work from the sofa. If that is the only option, at least set a timer to break it up.
- Train. A body that is strong through a decent range tolerates bad positions far better than a weak one does.
Point five is the one that lasts. Ergonomics reduces the dose. Strength raises your tolerance for it.
Why more core work is usually the wrong first answer
Almost everybody with an aching back has been told their core is weak, and almost everybody responds by doing more crunches, planks and sit-ups. It rarely works, for three reasons.
It is usually not a strength problem. Very often the trunk muscles are perfectly capable and simply are not being recruited in the right sequence, at the right moment, while breathing. That is a coordination issue and endless repetitions of an isolated exercise do not fix coordination.
Repeated spinal flexion may be the last thing an irritated back needs. Sit-ups and crunches bend the spine forward over and over. For some backs that is fine. For others it is exactly the movement that provokes symptoms, and doing hundreds of them daily in the name of protecting your back is counterproductive.
A plank of five minutes does not transfer. Being able to hold one position on the floor says little about whether your trunk holds together when you lift a suitcase off a conveyor with one arm.
So the first answers are usually hips, mid-back, breathing, carries and anti-rotation — and then progressively heavier whole-body work, because the back gets strong as part of a strong body rather than in isolation. Direct trunk work has a place. It is not the place people put it.
Symptoms that mean stop and see a doctor
This list is not exhaustive and it is not a diagnostic tool. It is the short version of what should send you to a doctor rather than a gym. If any of these apply, do not train, and get medical assessment.
- Loss of bladder or bowel control, or numbness around the groin, buttocks or inner thighs. This is treated as a medical emergency — go to a hospital, do not wait for an appointment.
- Numbness, pins and needles, or weakness in a leg or foot, particularly if it is getting worse, affecting both legs, or you are catching your toe when you walk.
- Pain that wakes you at night or is clearly worse at rest and unrelieved by changing position.
- Unexplained weight loss, fever, or feeling generally unwell alongside the back pain.
- Back pain that started after a fall, a road accident or any significant impact — extremely relevant in Pattaya, where motorbike incidents are common. Get imaged, not coached.
- A history of cancer, osteoporosis, long-term steroid use, or a suppressed immune system with new back pain.
- Pain that has been steadily and consistently worsening for weeks regardless of activity, position or rest.
Ordinary training soreness is dull, symmetrical, arrives a day or so later, eases as you move and fades within a few days. Anything sharp, electrical, one-sided, spreading into a limb, or accompanied by feeling unwell is a different category. If you are unsure which category you are in, that uncertainty is itself the reason to ask a doctor.
The referral pathway in Pattaya
If Jack thinks you need assessing, he will say so and he will not keep taking your money in the meantime.
The usual route is your own doctor or the hospital you are registered with, who can refer you on. If you want to go straight to physiotherapy, there are clinics in the area — TARA Physical Therapy and The Physio are two that operate locally. Jack has no formal relationship with either and no financial interest in where you go; ask your doctor for a referral if you would rather be pointed somewhere specific.
Two practical notes for expats and long-stay visitors. First, if you have insurance, check whether physiotherapy needs a doctor’s referral before you book, or you may not be able to claim. Second, bring any scans or reports you already have from home, even old ones — a clinician who can see what your spine looked like three years ago starts from a much better position.
And once you have guidance, training can resume around it. Very little of the body is genuinely off limits because of a back, and doing nothing for two months tends to make the situation worse rather than better.
Scope, one more time
Jack is a personal trainer. He is not a physiotherapist, a chiropractor, an osteopath or a doctor. He does not diagnose, treat or rehabilitate back pain, and nothing on this page is medical advice or a substitute for it.
What he offers is coaching: technique, programming, load management and progression, built around whatever a qualified clinician has told you. If you have a documented set of restrictions, bring them and the training gets built inside them. If you do not, get assessed first. That order round is not caution for its own sake — it is what makes the training worth paying for.
When you are ready, the first session page explains what the screen involves, and the condo and gym guides cover where sessions happen.
Frequently asked questions
Can Jack fix my back pain?
No, and anybody who says they can should worry you. He is not a physiotherapist and he does not treat or rehabilitate. He can coach you to move and load well around restrictions a clinician has assessed, which is a different and genuinely useful job.
I have a disc problem. Can I lift weights?
That is a question for the clinician who diagnosed it, not for a trainer or a website. Many people with a diagnosed disc issue lift perfectly well within specific limits. Get those limits in writing and Jack will build the programme inside them.
Should I stretch more?
Stretching creates a temporary range. Strength work is what keeps it. Most aching backs respond better to hip and mid-back work, loaded carries and anti-rotation than to more hamstring stretching.
Are planks and sit-ups the answer?
Usually not the first answer. Repeated spinal flexion can be exactly what an irritated back does not want, and a long plank does not transfer to lifting a suitcase one-handed. See why more core work is the wrong first answer.
What symptoms mean I should not train at all?
Loss of bladder or bowel control, numbness around the groin or inner thighs, worsening numbness or weakness in a leg, pain that wakes you at night, unexplained weight loss or fever, or back pain that started after a fall or crash. See red flags and get medical assessment.
My physio gave me exercises. Why would I also need a trainer?
Because rehab exercises get you out of pain and rarely get you strong. Most people finish physiotherapy with a sheet of movements and no plan for progressing beyond them. That progression is the part that reduces the chance of the same episode returning.
Training around a back you have already had looked at
Bring whatever guidance your physio or doctor gave you and Jack will build the programme inside it. If nobody has assessed it yet, get that done first.
