I see everyone starting to use these massage guns. I normally use a foam roller, softball, and lacrosse balls, and barbells. I Will admit though, this machine gets the work done in a fraction of the time and with less discomfort from traditional release and inhibition techniques. However, I feel it’s tougher to reach spots behind your back. In this case it depends on the model you are using(some may allow you better access to hit parts on the back of your body), or you may have to get a friend to help you.
I think these massage guns are great, but for overall full-body relief and restoration, traditional foam rolling, softball, barbells, and lacrosse balls are the still the way to go. Especially if you have to hit areas behind you.
With that being said, this is still very, very, Very good for beginners who know little to nothing, about self- mayo facial release and corrective exercises, or message therapy, etc, because you get a lot of release/relief from your muscles without going through a lot the pain associated with restorative practice; SMR, stretching, message. Just be careful. You should know a little about anatomy and the muscles you’re trying to recover. Don’t just go shooting yourself everywhere; bones, eyes, teeth, private parts.
