Whether you're heading back to the gym after the easing of pandemic restrictions or you're continuing to invest in home exercise equipment, online classes or fitness subscriptions, it's a good opportunity to make sure that you have the best tools for muscle recovery in your arsenal to help you reach your fitness goals. To achieve true workout recovery, you'll need a blend of nutrition and physical manipulation, but you can also take advantage of high-tech recovery tools meant to minimize muscle soreness (including the hard-to-resist CBD-infused activewear). If you're looking for a workout tool with science on its side, consider a Massage Gun.
Massage guns use the force of percussive therapy to manipulate your body's soft tissue. They're essentially backed by the same extensive scientific research that supports massage therapy as the optimal tool for sore muscles after a workout. Everyone from recreational gym-goers to professional athletes and people with chronic pain -- they all love these powerful massagers for many reasons.
Percussive therapy is said to help muscles recover faster while reducing muscle pain, muscle fatigue and lactic acid buildup. A percussion gun allows you to focus on a certain muscle group for immediate pain relief. They can also improve your range of motion and flexibility, encourage blood flow, help with muscle stiffness and more. Percussive therapy may even help with stress and sleep. Also, not that you should invest in one for this reason alone, but the slow-motion videos of massage guns punching muscles look insanely Insta-worthy. Just be careful with using one if you have any injuries beyond a muscle ache from a tough workout.
