As a guest or student, you might be asked by some fitness studios to book a class only with a signed waiver form. A waiver form is a liability form students must sign before joining a fitness class. The waiver form states that students are healthy to undergo training at the studio. If any injury occurs to the student, the signed waiver form waives any legal liability of the trainer or gym.
There are two places where you can be asked to read and sign a waiver form:
While booking a class
While creating your account
As per the center settings, acknowledge and sign the waiver form.
