doesnt the saying go "you cant over-train, you can only under-eat".

way way way back, when i lifted heavy i would ride to the gym and at times ride to the beach after. on leg day i always would stop for a bite to eat right after to give extra time for recovery and a refuel. but there were two times on crazy leg days that i bummed a ride home and the other caught a cab.

i dont see how anything other than abs, lower back and legs will cause a bike ride to be bad. if anything its best to hit cardio after as it will burn fat faster as your sugars are depleted during lifting and your body will start to hit your reserves (fat).
