Terms of Service
Last updated September 23, 2026
These Terms of Service ("Terms") apply to the personal training, Pilates and online coaching services provided by Papawadee Ongworawut, trading as ND Fitness ("We", "Us", "Our" or the "Trainer"), and to your use of the ND Fitness website at https://ndfitness.info (the "Website").
By booking or taking part in a session, buying a package, or using the Website, you ("You" or the "Client") agree to these Terms. If you do not agree, please do not book a session or use the Website.
Our services
We offer:
- Personal training: one-on-one sessions in your home, your condo gym or your gym, in the Bangkok area only.
- Online coaching: a personal workout program, nutrition advice and weekly progress check-ins, delivered online.
- Pilates: private, duo and small-group sessions, including reformer Pilates. Group reformer classes take a maximum of four people.
Every new client starts with a conversation about their goals and an assessment, so that We can design a program suited to them. The services, packages and prices currently offered are listed on the Website.
Your health and safety
Before you start
Before your first session, We will ask you to complete Our health questionnaire about your health, fitness, injuries, medical conditions and medications. You agree to answer fully and honestly, and to tell Us straight away about any change, including injury, illness, surgery or pregnancy.
If you have a medical condition, an injury, back pain, scoliosis, a heart or blood pressure condition, are pregnant or have recently given birth, or are unsure whether exercise is safe for you, you must get clearance from a doctor or other qualified health professional before you start. We may ask for written clearance, and may decline or pause training until We have it.
During sessions
Tell Us immediately if you feel pain, dizziness, shortness of breath, chest discomfort or anything unusual. You may stop any exercise at any time. We may stop or change a session if We believe continuing would be unsafe for you.
Not medical treatment
Our programs for lower back pain, office syndrome and scoliosis are exercise programs. They are not a diagnosis, medical treatment or physiotherapy, and do not replace care from a doctor or physiotherapist. Please keep following the advice of your own health professionals.
Nutrition advice
Nutrition advice is general guidance to support your training. It is not medical nutrition therapy and does not replace advice from a doctor or registered dietitian. Tell Us about any allergies, intolerances, eating disorders or medical diets.
Risk
All exercise carries some risk of injury. We take care to plan and supervise sessions safely, and you accept the normal risks of physical exercise when you take part.
Bookings
Sessions are arranged directly with the Trainer by LINE, phone or email. A session is confirmed when We have agreed a date, time and place with you.
Cancelling or moving a session
- Please give at least 24 hours' notice to cancel or move a session. We will rebook it at no charge.
- Sessions cancelled with less than 24 hours' notice, or missed without notice, count as used.
- If you arrive late, the session will still finish at the planned time.
- If We need to cancel or move a session, We will give you as much notice as possible and rebook it, or credit the session back to your package.
We may make an exception to these rules for illness, emergencies or other circumstances outside your control.
Packages and payment
- Prices are in Thai baht (THB) and are shown on the Website. We may change prices at any time, but a change will not affect a package you have already paid for.
- Single sessions and packages are paid in full before the first session they cover.
- Packages must be used within the period stated when you buy them. For example, the 10-session personal training package is valid for 30 days and the 20-session package for 90 days. Sessions not used within that period expire.
- Online coaching is paid monthly, in advance, and covers one month of coaching.
- Packages are for the person who bought them and cannot be transferred or shared without Our agreement. Duo sessions are for the two people booked.
- Payments are not refundable, including for unused or expired sessions, except where We cancel a service We cannot provide, or where a medical reason stops you from training and you provide a doctor's note. In those cases We may extend your package or refund the unused sessions.
Training locations
For sessions at your home, condo gym or gym:
- You are responsible for arranging access for the Trainer, including any building registration, visitor pass or guest fee your condo or gym charges.
- Please make sure there is a safe, clear space to train in, and that any equipment you want to use is in good condition.
- You must follow the rules of the building or gym where you train.
For Pilates sessions at the studio, please follow the studio's rules and the Trainer's instructions for using the equipment.
Online coaching
Your online program is written for you and is for your personal use only. You are responsible for doing the exercises safely, in a suitable space, and for stopping and contacting Us if anything hurts or does not feel right. Weekly check-ins depend on you sending Us your progress updates.
Results
Progress depends on many things, including your health, consistency, sleep, nutrition and effort outside sessions. We will work hard to help you reach your goals, but We cannot guarantee any particular result, such as weight loss, muscle gain or pain relief.
Clients under 20
The age of legal adulthood in Thailand is 20. Clients under 20 may train only with the written consent of a parent or guardian, who must also complete the health questions on their behalf.
Conduct
We expect sessions to be respectful on both sides. We may end a session, or stop working with a client, if We are treated abusively or if a client repeatedly ignores safety instructions. In that case We will refund any sessions that have not been used.
Photos and videos
We will only take photos or videos of you, or share them (for example on the Website or social media), with your permission. We may ask to film an exercise so We can check your technique. Those recordings are used only for your training, unless you agree otherwise.
Privacy
We collect and use your personal information, including health information you give Us, only to provide Our services. Our Privacy Policy explains how We collect, use and protect it, and your rights under Thailand's Personal Data Protection Act.
The Website
The information on the Website, including descriptions of services and prices, is kept as accurate and up to date as We can, but may occasionally contain errors. The prices and terms agreed when you book will apply.
The content of the Website, including text, images and logos, belongs to the Trainer or is used with permission. You may not copy or reuse it without Our written permission.
The Website may link to other websites, such as LINE. We are not responsible for the content or privacy practices of other websites.
Liability
To the extent permitted by law, We are not liable for:
- injury, loss or damage caused by information you did not give Us, or by not following Our instructions or your health professional's advice;
- exercise you do on your own, outside supervised sessions;
- loss of or damage to personal belongings during sessions;
- loss or damage caused by circumstances beyond Our reasonable control.
Nothing in these Terms limits or excludes any liability that cannot be limited or excluded under Thai law, including liability for injury caused by Our negligence.
Governing law and disputes
These Terms are governed by the laws of Thailand. If you have a concern about Our services, please contact Us first. We will do Our best to resolve it with you directly.
Language
These Terms may be provided in Thai as well as English. If the two versions differ, the English version applies.
Changes to these Terms
We may update these Terms from time to time. The "Last updated" date at the top of this page shows when they last changed. Changes do not affect sessions or packages you have already paid for.
