The truth is: your core probably isn’t that weak. Can you sit down and stand up? Can you get up off the floor? Yes and yes? Those core exercises you're doing in supine are probably not doing all that much for your strength.

All too often this is the cycle of traditional care with high performing/ active humans:

Patient comes in for knee pain. PT sees patient (under insurance) for knee pain and, usually, gets them out of knee pain. Patient returns to doing the same bs (mind my language) things they were doing before - fitness programming and lifestyle factors - that caused their knee pain in the first place, and boom, it returns. It’s cyclical and ineffective in the long term.

The simplicity of objectively getting stronger is anything but simple in the way in which it relates to life, especially life as a teenage girl. For one hour after school these girls get to turn off their phones, forget about the perception of the world, and focus on what their bodies can do, rather than what they look like on a grid on social media or walking down the runway, I mean hallway, of their middle school.
