I have been doing foundation since last February, and I have run into highs and lows in planche training. The highs for me have been knowing I am getting stronger in the position (planche leans) and realizing I can lean farther. The lows = muscle irritation every so often when I feel as if I am "pushing" myself too far. As of lately, I took a break from planche work for about two weeks due to my inside portion of my bicep (near the elbow on the medial side) becoming irritated. Although the only time it becomes irritated is when I RUB on it and then realize "Oh that feels kind of weird". Its as if I am scaring myself into thinking I'm on the verge of some huge injury. Has anyone experienced something along the lines of that before?
