Hyperice Hypervolt Portable Massage Device
I use the Hyperice Hypervolt Portable Massage Device ($349, originally $375) pretty much every day, and it leaves my muscles feeling so good afterward.
I foam roll a lot, but I feel like the Hypervolt is able to really target specific muscles that are sore or tight. I like that you can control the intensity of the massager, which is great for the days when I'm really sore. The Hypervolt device also comes with four interchangeable attachments which I really like because they hit my muscles differently.
