No one is arguing that treadmill running<\/a> and outdoor running are the same. From the surface type to the surrounding environment to the level of enthusiasm each typically elicits, there are a bunch of obvious differences.<\/p>\n

But do these varying features also translate to form<\/a> differences? In other words, when you move your workout indoors, should you also change how you run?<\/p>\n

Here\u2019s what run coaches advise their clients, plus common treadmill form mistakes<\/a> to avoid.<\/p>\n

Does your ideal running form change on a treadmill versus outdoors?<\/p>\n

We\u2019ll just cut to the chase: Whether you\u2019re running on a treadmill or striding outdoors, your form should basically be the same, Kai Ng<\/a>, a USATF- and RRCA-certified run coach<\/a> in New Jersey and New York, tells Runner\u2019s World. A big reason for this is continuity: \u201cYou don\u2019t want to one day learn treadmill skills, and then the other day practice outdoor skills,\u201d he says. \u201cAll that should be the same if you want to become a good runner.\u201d<\/p>\n

Keeping your form consistent also keeps things uncomplicated. Ng, who\u2019s been coaching for nearly a decade, says a big learning over his career is running should be \u201creally simple.\u201d That\u2019s because the more rules that exist, \u201cthe more complicated running becomes,\u201d he explains. And when that\u2019s the case, people are less likely to start running<\/a> in the first place, or to improve their performance<\/a> if they\u2019re already involved, he says.<\/p>\n

Olympian John Henwood<\/a>, a run and strength coach in New York City, tells Runner\u2019s World he takes a similar stance. He doesn\u2019t instruct his athletes to change their form when they hop on the treadmill. But, he adds, most people\u2019s form naturally does shift, albeit in one really subtle way.<\/p>\n

This form difference is thanks to the treadmill\u2019s moving belt. When you run outside, you have to put more energy into propelling yourself forward because the ground is fixed and thus isn\u2019t helping out on that front. This involves adopting a slight forward lean to better engage the muscles of your posterior chain, including your glutes, hamstrings, and calves, as these help power you forward.<\/p>\n

On the treadmill<\/a>, you don\u2019t need as much assistance from these muscles, so you naturally adopt a more upright posture. These postural differences are \u201cvery slight,\u201d Henwood says, adding that most people don\u2019t have to think about them; their bodies just naturally adjust.<\/p>\n

Okay, so we\u2019ve established that you should essentially have the same form whether you\u2019re running on the treadmill<\/a> or outdoors (aside from a slightly more upright posture on the treadmill, which you likely don\u2019t need to consciously think about).<\/p>\n

But beyond that, there are three common treadmill form mistakes people make that the coaches do advise trying to actively avoid.<\/p>\n

1. Shortening your stride.<\/p>\n

In Henwood\u2019s experience, when people are new to the treadmill and thus scared of falling off it, they tend to run in a slightly crouched position, which shortens their stride. And that\u2019s problematic because adopting too short of a stride can quash your forward momentum, as Runner\u2019s World UK previously reported<\/a>. Luckily, this one is easy to correct: Instead of hunching over, think about relaxing your upper body, opening your chest, and making yourself a little taller. With these cues, your stride will naturally open up, Henwood says.<\/p>\n

Related Story2. Expending your energy going up instead of forward.<\/p>\n

With running, the main objective is to move forward. And to do so, you have to push the ground backward, Ng says. But when you\u2019re on a surface that\u2019s already moving\u2014i.e., the treadmill\u2014this strategy can be forgotten. He finds that some runners\u2014perhaps due to a fear<\/a> of falling or unfamiliarity with the treadmill\u2014tend to jump up on the machine instead of forward, which just isn\u2019t efficient<\/a>.<\/p>\n

\u201cEven though you\u2019re running on the treadmill, don\u2019t forget that in order for you to move forward, you have to kick back,\u201d Ng says. Basically, avoid this mistake by focusing on pushing the belt behind you with every push-off.<\/p>\n

3. Adopting too low a cadence.<\/p>\n

Another form error that can creep in when folks are afraid of the treadmill is that they can sometimes inadvertently slow their cadence<\/a> in an effort to get more airtime, Ng explains. That way, \u201cthe belt moves, and they\u2019re getting this free distance,\u201d Ng explains. But this is a no-no, as adopting too low a cadence\u2014which Ng defines as 155 or fewer steps per minute\u2014creates a lot of impact on your joints, which translates to increased injury risk<\/a>.<\/p>\n

Instead, the treadmill should be thought of as a great tool to increase your cadence. \u201cThe treadmill is actually one of the best places to practice cadence,\u201d Ng says. And that\u2019s because of its predictability: Unlike outdoor running, you won\u2019t encounter unexpected obstacles, such as off-leash dogs, strollers, or groups walking six-wide on a path. Because of the limited distractions, all you have to do is set the treadmill to an easy-for-you pace<\/a> and focus on maintaining a steady cadence. Ng doesn\u2019t recommend a specific number of steps per minute to shoot for but instead says to think about kicking your foot back as soon as it touches the ground. \u201cBy doing so, most people will increase their cadence,\u201d he says.<\/p>\n
