Walmart offers the Gold's Gym Trainer 410 Treadmill, model no. GGTL39610, for $359. Opt for free Site-to-Store pickup to avoid the $19.97 shipping fee. That's $81 under the lowest total price we could find, although we saw it bundled with a 6-piece puzzle mat for $10 less in February. It features adjustable incline, eight workout apps, folding design, 2-lb. hand weight set, LCD display, heart rate monitor, and more.
