Getting the Most Out of the Treadmill :Jul 05, 2007Do you hold onto the treadmill while "walking?" The top excuses: Some people grip the front bar, yanking forward with each "step." Others grasp the side rails, shoulders bobbing up and down, body weight subtracted from the tread. And clinging on with one hand creates unequal stresses to the body. "Holding on and walking at top speeds is dangerous because of the ballistic hip rotation, over-striding and forward posture. It can lead to serious neck, back and knee injuries," says Calabrese. Standing straight while gripping won’t correct the situation. Some people don leather gloves for increased gripping traction, then proceed with their fake walking, legs wistfully moving through mere motions. But they’re tricked into believing they’re working hard because the settings are high: 4 mph, 12-percent incline! In the actual world, legs, knees, hips and back work in unison to support your full weight as you ambulate. Holding on, even lightly, takes valuable work away from your musculoskeletal and nervous systems. The calorie readout is triggered by the program setting, not the person on the machine! Walking hands-off burns about 20 percent more calories for the same length of time. "I’ve seen people increase the treadmill's elevation to augment the workload, then hold the handrails and lean back, defeating the entire purpose of the elevation," says Calabrese. |
