You can sleep your way to better golf.

Before you scoff and move on, one top fitness trainer is adamant that our sleep position can have a significant impact on our mobility on the course.

“It’s something that’s really overlooked with a lot of players,” said one of Golf Digest’s Best Fitness Trainers in America Darin Hovis during a recent Happy Hour.

During the hour-long webinar offered exclusively for Golf Digest+ members (which you can watch here), Hovis demonstrated numerous stretches that can improve your swing, but if you’re not as loose as you’d like, checking your sleeping position should be one of the first steps.

“Finding a comfortable position is different for everyone but the key is being mindful of what may be stressed by sleeping in awkward positions every night,” Hovis said. “Use the pillows to your advantage to find something comfortable that gives you a position that’s not going to compromise you over time.”

We all have our favorite sleeping positions, whether it be on our back, side or stomach, but while these may feel comfortable in the moment, if they are stressing a certain part of the body, then over time we will lose mobility and be susceptible to injury. The hips and low back, in particular Hovis says, can become tight over time when you sleep in the wrong position. That’s especially an issue for golfers, who need mobility in the hips and spine to swing properly.

Here’s how Hovis advises golfers adjust their sleeping position, depending on their preferences.

The Back Sleeper

“If you sleep on your back, it can be very helpful to put a pillow under your knees. This reduces extension stress on the low back,” Hovis said.

The Side Sleeper

“If you sleep on your side, place a pillow under the top knee to reduce rotation through the hip and the spine,” Hovis said.

The Stomach Sleeper

“If you’re a stomach sleeper, again, use pillows to your advantage so your head is not rotated 90 degrees either direction for an extended period of time,” Hovis said. “Positioning your head on the side of the pillow is one strategy. Also, placing a pillow underneath your hips can allow the hips to flex while not stressing the low back.”
