Giving other members admin status is a great way to help share the Planning of workouts for your members. Start by going to the gym drop-down in the header. Click on the "set admins" link.
Next, click the "admin" button located next to the name of the member you wish to make an admin. Additional admins will have all of the gym subscription holder's capabilities, including the ability to create workouts and Plan them as WODs for your members.
