As Khloe recently posted on Snapchat, she loves the Hyperice Vyper, which is essentially a vibrating foam roller. The company Hyperice reposted her video on their Instagram feed.
“This is one of my favorite things,” Khloe says.
The battery-powered Vyper has three different speed settings that you can use for myofascial release (a massage-like treatment that targets stiff connective tissues) or alleviating soreness.
“I think any foam roller’s great, but this one’s super-cool because it vibrates, so it gets into your muscles even more,” Kardashian explains. “And it really loosens everything up.”
The perks to foam rolling are legit.
“There have been studies that demonstrate that self-myofascial release (one approach is foam rolling) and local vibration training each can offer positive benefits, such as improved joint range of motion—especially when paired with various stretching techniques—as well as increased blood flow (to warm up for a workout and aid recovery),” says Jessica Matthews, M.S., professor of kinesiology and integrative wellness at Point Loma Nazarene University in San Diego, Calif, and author of Stretching to Stay Young. (That said, there isn't a ton of research on how the two techniques work when used together.)
No lie, foam rolling can hurt at first—especially if you’re particularly stiff (though the vibration does alleviate discomfort). But afterward, the release is like your muscles letting out a giant sigh of relief. And when you feel better tomorrow, you’re more likely to tackle another workout.
