Nah been doing core, back n shoulders for the last year or so. My knees aren't getting any better. That said my legs aren't scrawny cause I was part of track n field in high school. Thank god hahahah seeing guys at the gym who are huge but scrawny legs too funny
I'd try amayama, might be cheaper. Not very sure with gtr 35 parts in Australia but I'd imagine it's stupid expensive. Aftermarket probably be pretty good and price wise as well no?
