Yes, but I’m pretty sure I’m not using it properly or frequently enough. When I do use it, there is an improvement, but it seems to be temporary (which makes me think I’m not doing it frequently enough)…
I went for a cheap Chinese one as I wasn’t really convinced it would work, but was also not looking to be spending £35 a week on the pain a sports massage was inflicting sorting the legs.
A bit of proactive stretching and this gun and it did help, but the stretching quickly stopped so a combination of a few things needing picked up again and I reckon it would make a decent improvement – gun to help relieve knots and tension in the muscles and the stretching to keep things more supple.
Only real issue with it is trying to get it at the right angle for any back work – it tends to work best at 90 degrees to the surface, which is not really possible if trying to work on your back.
