Runner’s World highlights top features to look for when choosing a treadmill and adjustments that may help ease the impact of running on the knees according to Jordan D. Metzl, MD, sports medicine physician at HSS and others.

More cushioned treadmill decks are designed to help soften ones stride and withstand the impact of running. Like running shoes, there isn’t a one size fits all amount of cushioning, noted Dr. Metzl. He explained it’s more about paying attention to how the different levels make you feel - are you able to keep going an extra few minutes, for example, or bump up the speed dial by a couple of increments?

One of the benefits of treadmill running is the ability to adjust the incline as needed. Cranking your machine up can help ease discomfort in your knees, said Dr. Metzl, as it shortens your stride and reduces how hard you hit the ground. “I use uphill running for my patients with arthritic knees, those returning from injury, and for those trying to regain fitness and strength,” he cited. For anyone just getting started, Dr. Metzl suggested to set the treadmill at a 1.5 or 2.0 percent incline, then go up from there. “Increase the grade by 0.5 percent each time, until you feel you’re simultaneously working while comfortable." Most runners, typically find their sweet spot somewhere between 3 and 4 percent, he added.
