Percussion massagers are among the easiest ways to recover your legs after a hard run. The handheld devices are effectively jigsaws, using a reciprocating tip to strike your muscle tissue about 2,000 to 3,000 times per minute, which facilitates blood flow to the targeted area. More blood flow tends to reduce inflammation and soreness, expediting your recovery and making you ready to hit the pavement the next day. And yes, you can just buy a massaging tip for your jigsaw, although it won’t have purpose-built features like a big battery, rotating heads, and customizable settings.
