I hope you do more of these videos, I hike and walk a lot but I don't do other sports. Somehow and without being aware my shoulder started to hurt, mostly when laying down. I really hadn´t done anything to cause a lesion, but I was told it's a very normal lesion, sometimes the bones move and pressure the tendons. At the moment I'm doing some exercises to recover mobility (I can´t take clothes off hahah). Doing this workout tomorrow, will let you know :)
