Terms of Service

1.Using this site.Grit Blend Zone publishes this site so that people can see how the gym works before they walk in. Reading it costs nothing and commits you to nothing. Training with us is governed by the terms below and by the membership agreement you sign at the desk.

2.Memberships and packs.The unlimited monthly membership renews on the same date each month until you end it. The 8-class pack is valid for ninety days from purchase. A drop-in buys one class on the day. Prices are in Japanese yen, include consumption tax, and are shown on the classes page; if they change, existing members get thirty days' notice.

3.Booking and cancellation.Classes are booked through the desk or the booking link. You can cancel a booking up to six hours before the class starts. A later cancellation, or not turning up, counts as one class used from a pack and, for members, counts towards the three no-shows in a month after which we will ask you to book only on the day.

4.Freezing or ending a membership.A membership can be frozen for up to two months in any twelve, in whole-week blocks, for travel, injury or work. To end a membership, tell us in writing at least one calendar month before the next renewal date. Packs are not refundable but can be transferred to another person once.

5.The Foundations course.New members who have not trained with a barbell before take the four-session Foundations course before joining the strength classes. Coaches may ask you to repeat a session if a movement is not yet safe under load. The course fee is separate from membership and is not refundable once the first session has been taken.

6.Health and injury.You complete a health questionnaire before your first session and tell your coach about anything that changes. Coaching reduces risk; it does not remove it. You train at your own risk within the limits your coach sets, and you agree to stop and say so if something hurts. If you are pregnant, recovering from surgery or have a heart condition, we will ask for a doctor's note before you lift.

7.Gym floor rules.Indoor shoes only. Chalk stays in the chalk bowl. Rerack everything you used. Ask before filming, and never film another member without their agreement. A coach may end a session for anyone who ignores these rules or puts others at risk, without refund.

8.Personal training.One-to-one sessions are booked directly with the coach, usually in packs of four, and are valid for sixty days. Cancel at least twenty-four hours ahead or the session is charged. A coach who has to cancel on you will reschedule or add a session to the pack.

9.Guests and trial visits.Your first visit is free once you have filled in the questionnaire and spoken to a coach. Members may bring one guest a month to a conditioning class on a drop-in basis; guests fill in the same questionnaire and follow the same floor rules. Strength classes are members-only after the first visit because of the coaching ratio.

10.Content and ownership.The words and photographs on this site belong to Grit Blend Zone. Link to them freely; ask before copying them.

11.Disclaimer.Articles on this site describe how we coach; they are not medical advice. To the extent permitted by law we are not liable for loss that follows from applying them without a coach present.

12.Changes to these terms.We may update these terms when the timetable or the membership structure changes. The version on this page is the one in force; material changes are announced at the desk and by email.

13.Applicable law.These terms and the membership agreement are governed by the law of Japan. Disputes go to the Yokohama District Court as the agreed court of first instance.
