Simply login from your computer or mobile device, click group fitness/hot yoga (spin) and click on the class you wish to attend. If you do not have a username or password, your Membership Representative can set one up for you, or this can be done at the Front Desk. If you already have a username and password set up on Giga for tennis or squash, you may use the same login information. We also offer a certain number of walk-in spots onsite. The sign up sheet will be available at the Front Desk starting 1 hour prior to the class start time. Sign up is on a first come, first served basis.
