Free Workout for 10 days (up to 3 people)
I got the link from an instant win game piece, and
it appears that anyone who has the link can print it out.

Just Print out coupon on this page:

It's good for up to 3 people, consecutive days only though.
I know this is a promotion to sell their membership, but I don't think it's those usual guess pass thingies requiring orientation and stuff.
