Stride right at Sears this Black Friday

Trying to slim down? Stride over to Sears this Black Friday. A recently leaked circular reveals the store will be offering three solid treadmills.

The first: The ProForm XP Crosswalk 580, normally $900, will be on sale for $570. Overall, we found this product gets decent reviews. It has a 2.8-horsepower motor, a 20-by-55-inch walking belt and 12 personal trainer workouts. However, parts and labor are only covered under warranty for 90 days. About 80 percent of owners at Sears.com say they would recommend this treadmill to a friend, but several reviewers say the 580 shakes or buzzes loudly when jogging or walking fast.

Another offering: ProForm's CrossWalk 480 treadmill, normally $800, will be shaved down to $490 that day. Unlike the 580, it offers only six personal trainer workouts. Sears.com reviewers give it four stars out of five, but some say its belt is prone to slipping and its pulse monitor breaks down.

Lastly, The Nordic Track Incline Treadmill TS3, regularly a whopping $2500, is on sale Black Friday for $1300. The TS3 offers a zero to 40-percent incline, a 3-percent decline and a 20-by-55-inch belt for exercisers. One thing to note: Unlike traditional treadmills, incline treadmills offer more incline options to give exercisers a more intense workout. Additionally, since these products simulate uphill activity, some experts claim they can help you slim down and tone up more quickly. Conversely, treadmills that decline -- tip down in front, to simulate running or walking downhill -- work the same way, but tone different groups of muscles. Exercisers who do extensive indoor training for outdoor events, such as marathons, often find these features appealing. The Nordic TS3 offers exercisers both options. Most owners say the TS3 provides a great workout but a few complain about NordicTrack's customer service.
