knee aching scale:
1 foot jumping: guaranteed ache
2 foot jumping: minor ache sometimes
trap bar deadlift: very minor ache
deadlift: nothing
pistol squats: nothing
also, the knee pops when i extend it a lot, and i've actually made it a habit, like cracking your knuckles. there's like a sort of pressure that builds up like how it builds up with your fingers. sitting builds it up the most i think. if i'm seated for a while, i can definitely feel it building up, so i'll extend my leg, and it'll make a big pop and it'll relieve it lol.
the other way it "pops" is when i foam roll and i have pressure on the quad. this time though, there's a 100% chance of it "popping", but this feels like a different kinda. hard to explain, but when i do it it feels like theres like some kind of stuff in my knee, maybe scar tissue?
