I know we are all 6’4 jacked White boys here carrying 280 lbs. of invincible muscle, but sometimes even jacked White boys get back pain. For any of my Sherbrothers who are suffering from back pain and either haven’t seen success with or don’t have funds to seek out more expensive therapeutic solutions, I wanted to recommend any nail-bed technology that you use in-home. I've been having pain in my lower back (lumbar) for a few weeks and wake up pretty stiff in the mornings (Get your minds out of the gutter - I know you bozos). Been feeling great lately however and haven’t changed anything stretch-wise or whatnot other than lying daily on a nail bed. It opens my back up and sends a pulse or blood-flow throughout; I'd call it a de-stressor as well. In English language, I reckon it is called a tension mat or nail pad, but we call it piikkimattoja. This is the general idea of what I have been using: It hurts a bit at first if I’m being honest but every day, guys, 10-20 minutes depending on your pain threshold and schedule. Just wanted to throw that out there if any of my Sherbros are having back stiffness or pain and need relief. Cheers.
