It depends on the gym. Many of our gyms do include classes in a Hussle membership and you will normally find information on how to attend via the gym's profile page e.g. call or email to book in advance.
The difference between attending a class via Hussle or as a member of the gym is that the gym member can use the gym’s pre-booking system. At the moment we don't have class booking system integrations to allow for pre-booking.
If you have any questions about class access that you cannot find on the gym's page, please email our Customer Support team on info@hussle.com
