Massage guns have become common gym equipment, with member expectations ranging from dismissive to nearly miraculous — the reality sits in a more modest middle ground.
They support short-term muscle relaxation
Percussive therapy can temporarily reduce muscle tightness and improve short-term comfort, similar in effect to foam rolling but more targeted to specific spots.
They don't replace addressing the underlying cause
Recurring tightness in the same area is worth investigating rather than just repeatedly treating with a massage gun — it's a comfort tool, not a fix for an underlying movement or training issue.
