The Cross Trainer Burn Machine (a.k.a. The Ultimate Burn Machine, theburnmachine.com) may look like a cross between a torture device and a piece of modern art.

But doing a simple 15-minute full-body strength workout with the chrome-plated weight — while watching TV, no less – can almost take the place of a normal strength routine.

Each hand grip on the Burn Machine rotates 360 degrees, putting less strain on your wrists while making changes in hand position for its 21 moves a snap.

Boost the burn: Move the small sliding weight on the middle bar to either side to use more muscles as your body works to offset the imbalance.

Details: The Burn Machine comes in a variety of weights. At 12 pounds, the Intermediate Cross Trainer is probably the right weight for most women and the Professional Cross Trainer, at 20 pounds, is a good starting weight for most men. [source: Health]
