as a former weight lifter it was easy to know when you were over training. If you are lifting past 45-60 mins its over training. if you are lifting a body part more then 2 times a week its over training.

my question is with cycling how do i know when i am over training? I like to ride multiple times a week. If I go out and do intense intervals, the next day is ok to do it again? How often should I have a rest day? How many days in a row is it ok to go intense and hard (hill climbs, intervals, ect).
