Long time lurker here but a BPS fan and subscriber! The depth of content and Tom and Sam's level of explanation is something that is unique as I am a mechanical engineer by training. I really struggled to connect the reasons for certain movement and how it would benefit my skiing.
BPS has been the most educational and thought provoking source of so much information. I find it easy to just stream the content while commuting to and from the mountain and always have something to focus on and improve or examine.
btw, I'm also going for my L3 Alpine ski certification (again, lol) in just a couple of weeks and would not have made it nearly as far without BPS. I have taken all of the prep courses my mountain has offered, but that has not compared to the level of understanding as much as my BPS subscription has provided.
Tom is a genuinely great guy, and even on my pittance of ski instructor paycheck, it's absolutely worth keeping my subscription and other groups going on his site! Go check out the program and see for yourself risk free!
