Can massage guns from the likes of Theragun, Pulse Roll and others brands, help you warm up before exercise and recover more quickly after it?

Massage guns are one of the biggest-selling fitness devices of the past few years. They have a vibrating silicone head that delivers percussive pressure onto the muscle.

Manufacturers claim ‘vibration’ therapy increases bloodflow and helps the user warm up before exercise, perform better during it AND ease soreness afterwards. But does it?

Listener Clare got in touch after she bought one following a tip-off from a friend that they could help relieve aches and pains after a run (including a bad back) as well as her husband’s sore shoulder.

Greg Foot finds out if those claims are true by speaking to manufacturers, leading physiotherapists and scientists involved in the latest research.
