For a limited time, new visitors can get a FREE one-week pass to Curves, a nationally franchised women-only fitness and weight-loss center. They claim that their 30-minute strength training and cardio circuit workout exercises all major muscle groups and burns up to 500 calories — “up to” being the operative phrase. Curves has made this offer before, and as previously, it again does not set a sign-up deadline to test-drive their system at their many locations. The FREE week may be redeemed on the first visit or exchanged for a “special membership discount,” again unspecified. The offer is good at participating Curves locations. Click here to sign up. This offer sometimes sells out, so if this link doesn’t work, it’s gone. For more information, call 800-207-6606.
