Then tell me why these guys legs are bigger than 99.9% of the guys on here who are "trying" to get their legs to grow and are on a shit load of drugs? The leg growth these guys have are on after thought to theml. Also, I don't give a flying fuck what anyone said in Flex magazine.
Because 99.9 % of people on the G/O board either don't lift or don't train legs...
You've seen cyclists, on the road, and their quads look nothing like sprint cyclists do...plus, running is harder to do than cycling, that's why people go further on a bike---it's faster than running. A bike is a gyro that covers more land, with minimal effort, try running up a hill full speed versus riding a geared bike...sprint cycling is like track sprinting, so they would incorporate similar training.
Now, I know that Flex ain't the Bible of bbing, but just because you don't care for what is written in there, even Sports Illustrated commented and referenced the Flex article, in the Balco scandal...and I know you have your differences with Milos, but he WAS training Tim Montgomery and Marion Jones.
Colleges incorporate high rep squats for explosiveness for sprinters. As I said, if doing sprint work would give you huge quads, then there would be tons of HS sprinters w/no weight training who had huge quads for their size. There are none.
