What's bothering you?

Do any of these sound familiar?

Back pain holding you back?

Pain is a signal, not a sentence. Together we'll find the root cause.

No energy throughout the day?

That's not normal. A few weeks of proper movement and you'll feel the difference.

Tried other trainers with no results?

I know what went wrong. Let's start with what actually works for you.

Want to lose weight but don't know where to start?

No miracle diets, no suffering. Small steps that actually work.

Need nutrition tips but not a full dietitian?

I'm not a dietitian, but I'll help you build healthier eating habits step by step.

What I offer

Choose the training format that suits you.

Personal training

One-on-one sessions tailored to your goals and abilities. Full attention, technique correction, and a custom plan.

Small groups

Training in groups of 2–4. Still individual approach, but with motivating atmosphere and better price.

Group classes

Group energy, shared motivation. Classes for all levels – from beginners to advanced.

How it works

Four steps to your plan. No commitment.

01

Health questionnaire

You fill out a short questionnaire about your health, goals, and activity history.

02

Functional assessment

I check how you move, what hurts, where the limitations are. Without this, there's no good plan.

03

Custom training plan

Based on the questionnaire and assessment, I create a plan tailored to you – not to a generic client.

04

Training & monitoring

We start working. I regularly analyze progress and adjust the plan to keep results moving forward.

Online coaching

Train wherever you are – I guide you step by step.

You get a custom training plan, and after each training cycle I prepare a detailed progress report. We review it together via video – I explain what's working, what needs to change, and why. Everything step by step, so you fully understand what we're doing.

1

Questionnaire & video call

We meet online – you fill out a questionnaire, then we discuss your goals and limitations.

2

Custom training plan

I build a plan tailored to you and your equipment. You get detailed descriptions for every exercise.

3

Report & video review

After each cycle I prepare a progress report. We review it on video – I show what to change and why.

4

Adjustments & growth

Based on the report I modify the plan. You always have direct contact with me for questions.

Who am I?

I didn't become a trainer to count reps for people. I became one because I saw too many people walk into the gym with hope – and leave with frustration. I want you to feel good in your own body. No BS, no magic methods.

  • Specialization: back pain, weight loss, return to activity
  • Certified personal trainer and gym instructor
