HEATED MASSAGE FOR IMMEDIATE RELIEF – Both heat and massage provide rapid relief to sore muscles and aching joints. With our built-in heated option, the muscle massager fuses these two highly effective elements together for an intensely powerful deep tissue massage. Use the included heated attachment to ease tension throughout the body – soothing hard-to-reach-areas, reducing sore muscles, relaxing stiff joints, and calming muscles spasms.ALLEVIATE CHRONIC PAIN & LONG-TERM INJURIES – If you have chronic pain, you’ve probably learnt to live with it, masking your discomfort with a regular regimen of painkillers. But what if you could fix the underlying issue? Through the combined strength of heat and massage, the Sonic FX deep muscle massage gun increases blood flow to problem areas. This in turn reduces pain and inflammation, relieving chronic pain, healing old damage, and accelerating recovery from an acute injury.SHORTEN YOUR RECOVERY TIME: After an injury or workout, the body repairs itself – but slowly. Our percussion massager intense vibrations wake up muscles throughout your body, triggering myofascial release and enhancing your body’s ability to regenerate cells and repair itself, so you need less downtime between workouts. This muscle gun comes with 5 intensity levels so you can adjust your speed to suit your need.NONSTOP SESSIONS WITH A SWAPPABLE & RECHARGEABLE BATTERY: The Sonic FX battery runs for up to 5 hours on a single charge so you can book back-to-back on sessions without stopping. Additional battery packs are available for purchase separately, so if your first battery runs out, you can simply swap and keep going. Included pause button helps you put your session on hold, then pick right back up where you left off.
