In brief
- An ache, old injury or health condition does not automatically rule out personal training.
- Your trainer should adapt the exercise and respect healthcare advice.
- PT is coaching, not diagnosis. When something is clinical, get the right healthcare professional involved.
Tell your trainer what is going on
You do not need to arrive with a perfect body and a clean injury history. Tell your trainer about anything that affects exercise, including old injuries, current symptoms, medication or advice you have already been given.
That information helps us choose a sensible starting point. Hiding a problem because you are worried it will stop you training usually makes the job harder, not easier.
Exercises can usually be adjusted
If one movement is uncomfortable or not appropriate, there is often another way to train the same area or goal. We can change the range, load, speed, equipment or exercise completely.
The aim is not to force you through a movement because it is written on the plan. The plan should change when the person in front of us needs it to.
A personal trainer does not diagnose
This is an important line. A PT can coach exercise, monitor how you respond and work within advice you have already been given. We cannot diagnose an injury, change medication or tell you that a medical symptom is nothing to worry about.
If something needs clinical assessment, I would rather pause that part of the plan and get the right person involved.
Sometimes clearance should come first
The NHS advises speaking to your GP before exercising if you have not exercised for some time, or if you have medical conditions or concerns. Whether you need clearance depends on your situation.
If you have new or unexplained symptoms, a recent operation or injury, or your healthcare team has given you restrictions, get the appropriate advice before pushing on with training.
Start at the right level and build confidence
Once it is appropriate to train, we start with what you can do now. That might look easier than what you think a “proper workout” should be. That is fine.
The goal is to build strength and confidence step by step, then progress as your body and your healthcare advice allow.
- Be honest about symptoms and previous advice.
- Use exercise options that feel manageable and appropriate.
- Build gradually instead of trying to prove what you can tolerate on day one.
