well i played with RTO on rings, i did 5x30s at the first attempt. following a pic of my form
I'm not experimenting soreness or doms but I have always a sensation of fear. Probably i'm currently ablet o hold a cross but i'm scared about it.
Another my friend in the calisthenic world completely torn his biceps tendon, another big part of them have elbows tendonitis. I know they did not my same approach as GST. I spent the last 1 year and half (probably more) on foundations in order to prepare my elbows. but seems that mentally this is not enough, i know what role plays and injury as a tendon rupture for a gymnast, especially now that i'll start some light competitions in this autumn.
