Hi folks. I am 6'1 and 150-155lbs, I compete in marathon and distance running races. I run mostly 7 days per week. I am just getting started with S&S and wanted to see how often would you suggest I do it to progress to the Simple standard for now while enhancing my running without wearing me out too much. I also plan to have at least 1 day per week to practice some deadlifts and some occasional calistenics. Would I be able to make progress in S&S with 2-3 days training per week or would you aim for 4-6 days per week?
