If you love getting a good workout in — complete with clothes drenched in sweat and that familiar burning feeling in your muscles — it’s likely you’ve also experienced the not-so-pleasant aftereffects of said workout. A few good elbows in the back (or 15 minutes with a deep percussive massager) can work some serious magic on post-workout soreness, not to mention leave you with a sense of calm. As it turns out, those benefits aren’t just anecdotal. Nope: The power of massage therapy is backed by decades of scientific research.
