Get A Theracane–AND Use it often
Make no mistakes about it, the theracane and or back buddy is a tool you must have. It is a very convenient tool to have at your leisure when you experience tension in hard to reach places like your infraspinatus, rhomboids, etc. You can bring it with you anywhere, whether it’s work, car, home, gym.
There are many different versions and varieties of the theracane but I recommend one with the two nobs in the arch because it’s great to use on the back of the neck along the cervical spine and into the occipitals (muscles at the base of the skull).
