I read a lot in the fitness world about "overtraining."  Does this really apply to blood type Os?  I've always been able to exercise 5-6 days a week at least.  Are we harming ourselves by doing this or is it in fact harmful for a blood type O to not exercise just about every day?

Depends on the type of exercise and your age.

Younger hunters need more of an outlet. Older hunters need less (less catecholamines).

I hate being old.  Ha just kidding.  I exercised like a maniac when I was young.

I consider working at normal things better then mad exercising..

I mean why spend time on things that get you nothing.. plant food instead .. the bending will do you good, pull weeds in some old ladies garden it will do you good, make your body help to have sparkle windows inside and out - stretch.. go for a nice walk, enjoy the world.. why spend it indoors.. use a bike, go skying, sledding.. I mean there is so much more to us then going to the gym .. doing repetitive movements..

Unfortunately, every person on earth can overtrain.  Blood type has no bearing on this at all.  There have been outstanding athletes of various blood types.

Training smart and correctly is what gives you explosive power, stamina, and real strength.  When fitness increases, more training can be done with less recovery time, but we all need recovery.

Exercising every day for an hour or two is not overtraining if you train smart and keep in shape.  I exercise at least 1 hour 6-7 days a week.  

I workout 6 days a week and sometimes 2 hours a day. Do what feels right for you. Of course, we all can overtrain, but if working out makes you feel good, then do it.

I shortened my workouts this week but who knows, maybe I actually need longer workouts.
