Most women who book a first personal training session have never been to a trainer before. The anticipation is often worse than the session itself. You imagine being weighed in front of someone, pushed through exercises you hate, and ending the hour feeling worse than when you started.
None of that has to be true. Here is exactly how your first session runs at Flex Fitness in Southampton — no mystery, no awkwardness, and no obligation to continue afterwards.
Before you arrive
You do not need to do anything special in preparation. Do not "eat clean" for three days beforehand, and do not try to arrive fitter than you are. Your trainer needs to see you as you actually are, not a curated version of you.
What to bring:
- Comfortable clothing you can move in — leggings and a t-shirt is the classic answer.
- Trainers with a flat, stable sole. Running shoes are fine; sliders and boots are not.
- A water bottle.
- Any relevant medical information — medications, injuries, pregnancy, or conditions your physiotherapist or doctor has told you about.
- Any previous exercise plans or gym apps you have tried, so we can see what did or did not work.
You do not need to be fit, thin, or confident to book a first session. You only need to turn up. The rest is my job.

Minutes 0-10: the conversation
We start with a proper chat, seated, with a cup of tea. I want to understand three things before I look at a single weight or movement.
What you actually want
Not what you think you should want. Not the body you saw on an influencer's page. What do you want your training to change in your life?
- Feel stronger and safer in your body?
- Lose weight and stop it creeping back?
- Get back to running, or play with your children without getting tired?
- Manage a medical condition or recover from injury?
- Prepare for or recover from pregnancy?
What you have done before
Plenty of people have tried things that did not work, and that information is genuinely useful. A programme you hated teaches me more about what will actually work for you than a blank page does.
What your week really looks like
This is the most important part. I do not care what your ideal week looks like — I care what your real week looks like. If you work shifts, have three children under five, or train for a marathon, your programme has to live inside that. I would rather write you a realistic three-session plan you will actually do than a six-session plan you will abandon in a month.
Minutes 10-25: the assessment
Now we look at your body and how it moves. This is not a judgement — it is a starting point. Skipping it is like planning a driving lesson without checking which side of the road you drive on.
Measurements and history
With your permission, I record simple measurements: waist, hip, and (if you want) body fat percentage. I want to be transparent about this — I do weigh my clients, and I do not judge them by the number. The scale number is genuinely one of the least useful pieces of data I collect, and chasing it is one of the fastest routes to frustration.
A far better measure is a progress photo taken in the same lighting and pose each time, plus strength and performance markers like how much you can squat or how many push-ups you can do. Those numbers improve reliably even when the scale stalls.
Movement screen
This is where we identify asymmetries and mobility limits that could predispose you to injury. I watch you squat, hinge, push, and pull, and I test your hip, shoulder and ankle range of motion.
| Test | What it tells me |
|---|---|
| Goblet squat | Ankle mobility, hip range, core control, and whether your knees track correctly |
| Hip hinge (RDL) | Hamstring length and the ability to bend at the hips without rounding the spine |
| Overhead press | Shoulder mobility and upper back strength |
| Push-up | Upper body strength and trunk control |
| Single-leg balance | Hip stability and ankle control — important for knees and ankles |
Minutes 25-50: your first session
Now the fun part. We do a short session built entirely around your results from the screen — not a generic workout from a template.
The golden rule: light loads, perfect form
Your first session should feel almost too easy. You should finish feeling energised, not wiped. I want you to leave knowing what the movements feel like when they are done correctly, and feeling capable of coming back next week.
Why I keep it light
Building habits, not fitness, is the goal of session one.
Heavy loads on day one often cause soreness that lasts four days, which is the fastest way to never book a second session. Light loads and good technique mean you recover fast, feel capable, and come back.
Your plan
At the end of the session, I give you a clear, simple plan. It should cover:
- Two to three sessions per week — your ideal, and your realistic version of it.
- The exercises, with written descriptions or a video so you remember them at home.
- What "hard enough" feels like, in plain English. Most women under-rate their effort by about 40%.
- A simple nutrition starting point — usually one or two changes, not a full overhaul.
After your session
You will be mildly sore for 24-48 hours. That is normal and it fades fast if you have trained lightly. Some light movement — a walk, gentle mobility — helps more than sitting still.
You will also likely feel embarrassingly happy. This is the most common message I get from first-time clients the next day.
Most women say the hardest part was booking the session, not doing it. Once you walk in, the nerves disappear in about three minutes.

Warning signs to watch for in any trainer
Your first session is also a chance to evaluate me. Here are some things that should make you walk away, whatever the discount or the "first session cheap" offer:
- Body shaming. If you feel judged or insulted, leave. Your trainer should be your biggest cheerleader, not your harshest critic.
- Hard selling and pressure. A good trainer lets results speak. A bad one tries to lock you into a twelve-month contract on day one.
- No assessment. If they start your first session with a fixed routine without asking about your history, they are not personal training — they are group class delivery.
- Only ever showing you the same 3 exercises. A real programme progresses. If you do the same 3 lifts for 12 months, you have been sold a membership, not coaching.
- Guaranteed results. Anyone promising "10 pounds in 2 weeks" is lying, and will likely pressure you into an unsustainable diet to deliver it.
Questions worth asking
Ask me directly:
"What qualifications do you hold, and are you insured?" · "Can you show me my programme in writing before I pay for anything?" · "What happens if I need to cancel or pause?"
Any trainer worth hiring answers all three in a straight minute, without defensiveness.
If you are in Southampton and want to book your first session, it is a simple conversation. I explain the package options up front, you decide, and we go from there. Or if you would rather start at home first, my mobile personal training and online coaching are both great ways to begin without committing to a studio session straight away.
Frequently asked questions
? Common questions about your first session
Comfortable clothing you can move in and trainers with a flat, stable sole. You will not need to change into anything specific, and you are not required to wear branded clothing. Supportive sportswear and a water bottle are all you need.
No. The first session is deliberately light. The priority is assessment and learning good technique, not exhaustion. You should finish feeling energised rather than wiped out, so you are comfortable booking the second one.
Not at all. In fact the people who benefit most from personal training are usually the ones who feel least fit. Every programme I write starts at the level you are at today and builds from there.
No. All assessments happen in private. And I would gently push back on weighing clients as a motivator anyway — changes in body composition can happen while the scale number barely moves, and that confusion causes people to quit.
No. The first session is an assessment and a plan, with no obligation to continue. You can decide afterwards whether the fit feels right. A trainer who pressures you into a long contract on day one is a warning sign, not a good deal.
