why is weight lifting for too long of a session bad?

Question

i know that if you lift for 2 hours straight its too much, but why is it "bad" for you?

Answer 1

there are 3 main reasons:

#1 - if it takes 2 hours to complete your training you are either taking too many breaks between sets and/or exercises or not training at a high enough level of intensity.

#2 - there is only so much you can do to stimulate a muscle in one training session. like with many things more isn't always better. quality beats quantity any day of the week.

#3 - the levels of catabolic hormones increase drastically after long training sessions. this is counter productive to recovery and mucle growth

Answer 2

Any type of exercise done for too long becomes detrimental. You will begin to tear down the muscles. After a work out the muscles get stronger during the recovery cycle, which is why you do not work out on consecutive days.

Answer 3

Well, it simply over-works your mucles. The cells work to hard and they can die from it, thus meaning a loss of muscle mass and making your whole workout worthless. So... that's why

Answer 4

When you get tired the risk of injuring yourself becomes greater. That is why. Stop before you become exhausted like you would snow skiing.
