You may have seen Theragun popping up all over your favorite fitness influencers' Instagram accounts lately, and there's a reason why: The deep tissue percussive massager is great for treating sore muscles. There are three versions of the product, but the Theragun G3PRO is the most powerful of them all.

Think of the Theragun as an alternative to taking Ibuprofen after an intense leg day at the gym. According to the product description, the massager works by increasing blood flow to support the body's natural recovery process through a powerful massage. In addition to sore muscles caused by working out, you can also use it to relieve tension in your shoulders or feet caused by your everyday work routine or for chronic pain relief.

The G3PRO uses fast, repetitive strokes at 29 times per second or 40 times per second to stimulate blood circulation and generate heat. To use, you want to lightly float the massager over your muscles, being careful not to apply too much pressure. The brand also has an app with guides on how to treat different parts of your body for maximum effectiveness.

“I’ve had my Theragun for about 2 months now and it has changed my life for the better,” one reviewer wrote on Theragun’s website, who said it helped treat their plantar fasciitis and sore muscles. “I do not want to be without my Theragun ever again. I’ve also recommended it to friends and those who have gotten one say the same thing. It has definitely been worth the investment.”

"I love my G3Pro," wrote another reviewer. "I have a lack of mobility in one knee from 2 surgeries (ACL and meniscus). The first day that I received my G3Pro, I started working it on my knee and saw some immediate mobility gains. The G3Pro has quickly become an integral part of my nightly mobility work. I'm about to go on a work trip for two months and you can bet that I will be taking the G3Pro with me."

The Theragun G3PRO comes with six attachments for treating different muscle groups, as well as swappable batteries and a travel pouch for taking on the go. However, there is also a cheaper version with a few less attachments and only one speed called Theragun liv (on sale for $199, Orig. $249) if you don't need the pro version.
