One thing I've learned over the years with my clients and athletes is most don't care about the scientific bullshit, I could talk science, give them case studies on why I do the things I do till I'm blue in face....they dont give a shit, they just want to be trained, period. I see this with Troponin, dude knows his stuff for the most part but reality is people dont care about science, they just want to know what you can do for them. If they ask why, then tell them. Long story short, tell them the why's and how but if you start baffling them with scientific BS....you lose them and that can basically care less.
