Just an opportunity to say things that you learned the hard way, things that you had no idea about. Ill start. I learned the hard way... that PAS, or pain relieving patches, if used together with those hot pads, can give you a burn. Honestly, had no idea. that stretching your both hamstrings together can put alot of workloads on your back, enough to severely damage it. that standing on your hands can get your shoulder dislocated This isn't meant to be a health and fitness thread, but as it turns out, that's where I lacked a bit of knowledge. Please do carry on..
