The short version

This summary is for convenience. The full text below is what applies.

1. Agreement

These Terms of Use (the “Terms”) are a legal agreement between you and GrindSplit LLC (“GrindSplit”, “we”, “us”, “our”) that governs your use of Move Better Athlete at movebetterathlete.com and any related pages, content and features (together, the “Site”). Our Privacy Policy is part of these Terms.

By using the Site, you agree to these Terms. If you don't agree, please don't use the Site. Please read sections 4 and 11 to 13 (health risks and limits on our liability) and sections 15 to 17 (how disputes are resolved) carefully.

2. Who can use the Site

The Site is for people aged 13 and older. It is not for children under 13. If you are under 18, you may use the Site only with the permission and supervision of a parent or legal guardian, who should read and agree to these Terms. By letting a minor use the Site, the parent or guardian agrees to these Terms on the minor's behalf and takes responsibility for the minor's safe use of the content.

3. What the Site is

Move Better Athlete is a free website that offers a short daily routine of breathing, soft-tissue (rolling), mobility and stretching exercises, along with general educational information. We may change, add, suspend or remove any part of the Site, or the Site itself, at any time and without notice. The Site is free, and we don't promise it will always be available, error-free or compatible with your device.

4. Health, safety and assumption of risk

Not medical advice. Ease off if anything hurts. Stop if you feel sharp pain, numbness or tingling. Skip any area that's injured, and check with a doctor or athletic trainer if you're hurt.

Not medical advice. The Site provides general fitness and educational information only. It is not medical advice, diagnosis or treatment, and it doesn't create a doctor–patient, trainer–client, coaching or other professional relationship. It is not a substitute for advice from a physician, physical therapist, athletic trainer or other qualified professional who knows your situation.

Check first. Talk to a qualified professional before using the Site, and especially if you have or are recovering from an injury, surgery, illness or medical condition, are pregnant, have heart, breathing, balance, joint, bone or nerve problems, take medication that affects exercise, or have been told to limit activity. Do not use the Site if a professional has told you not to do these kinds of exercises.

Listen to your body. Stop immediately and seek appropriate care if you feel sharp pain, numbness, tingling, dizziness, lightheadedness, chest pain, shortness of breath or anything that feels wrong. Use mild to moderate effort, as the exercises instruct. Never roll over your spine, neck, bones, joints or an injured area.

Your space and equipment. Exercise in a clear, safe, non-slip space. Many exercises suggest household items (such as a wall, chair, couch, bench, step, doorway, towel, water bottle or broomstick). You are responsible for choosing items that are stable, sturdy and suitable, and for using them safely. Don't use anything that could slip, tip, break or give way. Younger athletes should be supervised as appropriate.

Assumption of risk. Exercise, including the activities in the Site, carries inherent risks, including muscle strains, sprains, falls, aggravating an existing condition, and in rare cases serious injury or death. By using the Site, you voluntarily choose to participate and, to the fullest extent permitted by law, you accept and assume all of these risks, and you release GrindSplit and its owners, members, managers, officers, employees, contractors and affiliates (the “GrindSplit Parties”) from any claims, losses or liability arising from your use of the Site or its content. If you are a minor, your parent or guardian gives this release on your behalf.

5. Information only, and no promise of results

Content on the Site, including the exercises, descriptions and summaries of research, is general information that we've tried to keep accurate and up to date, but it may be incomplete or change as understanding evolves. We don't guarantee any result, such as flexibility, range of motion, soreness relief, recovery or athletic performance. Results vary from person to person. Nothing on the Site is a promise to prevent, treat or cure any injury or condition.

6. Your device and your data

Your streak, history and settings are stored only on your device (see our Privacy Policy). We don't have a copy and can't restore it. You are responsible for your device and browser. We aren't responsible for lost, cleared or corrupted data, including a lost streak (for example, if your browser clears site data, you change devices, or you reset the Site).

7. Acceptable use

You may use the Site for your own personal, non-commercial purposes. You agree not to:

  • use the Site in violation of any law, or in a way that could harm others;
  • copy, republish, sell, rent, sublicense or commercially exploit the Site or its content (including the sessions, exercise text, designs and Jay artwork) without our written permission;
  • scrape the Site in a way that burdens it, or probe, attack, overload or try to gain unauthorized access to the Site or its hosting;
  • reverse engineer or tamper with the Site, except where the law allows;
  • remove or hide ownership notices, or suggest that you or your product is affiliated with or endorsed by GrindSplit or the Site without our permission.

8. Ownership and licence

The Site and everything on it, including the design, text, exercise content, session plans, the mascot Jay and its artwork, and the names and logos “Move Better Athlete” and “GrindSplit”, are owned by GrindSplit or its licensors and are protected by copyright, trademark and other laws. We grant you a limited, personal, non-exclusive, non-transferable, revocable licence to use the Site as intended. All other rights are reserved.

The Site uses the fonts Outfit and Manrope, which are licensed under the SIL Open Font License 1.1 (see Outfit licence and Manrope licence). Sport names and uniforms shown on Jay are generic, and the Site isn't affiliated with or endorsed by any league, team, brand or organization. Other names and trademarks belong to their owners.

9. Feedback

If you send us ideas or suggestions, you agree we may use them freely without compensation or obligation to you.

10. Third-party sites and GrindSplit

The Site links to other websites, including GrindSplit's website and app and research sources. We don't control third-party sites and aren't responsible for their content, accuracy or practices. GrindSplit's apps and services have their own terms and privacy policy that apply when you use them.

11. Disclaimers

The Site and all content are provided “as is” and “as available”, without warranties of any kind, whether express, implied or statutory. To the fullest extent permitted by law, the GrindSplit Parties disclaim all warranties, including implied warranties of merchantability, fitness for a particular purpose, accuracy, non-infringement, and that the Site will be uninterrupted, secure or error-free. Some places don't allow certain disclaimers, so some of this may not apply to you, and you may have rights that can't be waived.

12. Limitation of liability

To the fullest extent permitted by law:

  • the GrindSplit Parties will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for lost profits, lost data, or loss of goodwill, arising out of or related to the Site or these Terms, even if we were told such damages were possible; and
  • the total liability of the GrindSplit Parties for all claims arising out of or related to the Site or these Terms will not exceed US$100 in total (because the Site is free).

These limits apply whatever the legal theory (contract, tort including negligence, or anything else). Nothing in these Terms limits or excludes liability that cannot be limited or excluded by law, such as liability for fraud, or for death or personal injury caused by negligence where the law of your country doesn't permit us to exclude it. Some places don't allow certain limits, so some of this may not apply to you.

13. Indemnity

To the extent permitted by law, you agree to defend and indemnify the GrindSplit Parties against claims, damages, losses and reasonable costs that arise from your violation of these Terms or your misuse of the Site. For a minor, this applies to the parent or guardian only to the extent permitted by law.

14. Changes and ending

We may update these Terms from time to time. We'll change the “Last updated” date and, for significant changes, tell you on the Site. If you keep using the Site after an update, you accept the new Terms. You may stop using the Site at any time. We may suspend or end your access at any time for any reason. Sections that by their nature should continue (including sections 4 to 6, 8, 11 to 13, 15 to 17 and 19) survive.

15. Governing law

These Terms and any dispute relating to the Site are governed by US federal law and the laws of the state in which GrindSplit LLC is organized, without regard to conflict-of-law rules. Subject to section 17, the state and federal courts located in that state have exclusive jurisdiction, and you consent to them. If you live in the EU, UK or another place with mandatory consumer protection laws, you keep the protections those laws give you that can't be waived, including the right to bring a claim in your local courts.

16. Talk to us first

If you have a dispute, please email support@grindsplit.ai with a short description and what you'd like us to do. We'll try to resolve it informally within 30 days before either of us starts a formal proceeding.

17. Arbitration and class action waiver (United States)

This section applies to users in the United States. Please read it carefully: it affects your legal rights.

If we can't resolve a dispute informally, you and GrindSplit agree to resolve it only through final and binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, instead of in court before a judge or jury. The arbitrator may award the same individual relief a court could. Arbitration may be conducted by video or in writing, and we'll pay the fees we're required to pay under the AAA's consumer rules.

Exceptions. Either of us may (a) bring an individual claim in small-claims court if it qualifies, and (b) ask a court for an order to stop infringement or misuse of intellectual property.

No class actions. To the fullest extent permitted by law, you and GrindSplit each agree to bring claims only in an individual capacity and not as a plaintiff or class member in any class, collective or representative action. If this class waiver is found unenforceable for a claim, that claim must go to court rather than arbitration.

Opt out. You may opt out of arbitration within 30 days of first using the Site by emailing support@grindsplit.ai with the subject “Arbitration Opt-Out”. If you are a minor, a parent or guardian may opt out on your behalf.

This section doesn't apply where the law doesn't allow it.

18. Accessibility

We want the Site to work for everyone and aim to follow the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA. If you have trouble using any part of the Site, email support@grindsplit.ai and we'll work with you.

19. General

  • Entire agreement. These Terms and the Privacy Policy are the whole agreement between you and us about the Site.
  • If a part is unenforceable, that part is limited or removed to the minimum extent needed, and the rest stays in force.
  • No waiver. If we don't enforce a right, we haven't given it up.
  • Assignment. You can't transfer these Terms. We may transfer them as part of a merger, sale or reorganization.
  • Beyond our control. We're not responsible for delays or failures caused by events outside our reasonable control.
  • Electronic notices. We may give you notices by posting them on the Site.
  • Headings are for convenience only.
