Walmart offers the ProForm 905 CST Treadmill bundled with the Gold's Gym AbFirm Pro for $649.64 $649.99. Opt for in-store pickup to avoid the $49.99 shipping charge. That's $100 under our August mention of the treadmill alone and $11 under the lowest price we could find for these items purchased separately elsewhere. It features a 5" backlit display, 30 workout apps, EKG heart rate monitor, 20" x 60" tread belt, digital speed and incline controls, fan, tablet holder, and sound system.
