tension

So I read this: The Tension Day | StrongFirst So this might be a game-changer for me. I do mid- to high-level calisthenics on top of Simple & Sinister (some recent stalling not withstanding). So would/could a tension practice session be composed of calisthenic static holds or slow dynamics...

basically just wondering how. on the one hand I'm getting better at HTT and am generating more tension by the day. the downside is that I'm starting to get a lot of the tension spill over into my head, especially when clenching the fist the vein in my head goes crazy and I feel like that...
