Drew, can you please expand on what you mean about parasympathetic training please?
I was just being stupid really but it has a basis in reality, in so much as a lot of hard high intensity work like oly or dead lifting etc mixed with met con, interval training and things like that take their toll, they all exist in the realm of the sympathetic nervous system.
If you mix these with other sympathetic nervous system based processed like the stress of running your own business etc etc then you get a little off balance.
Indeed you can 'overtrain' both parts: sympathetic if you're a sprinter (example symptom: increase in hear rate) parasympathetic if you're an endurance athlete (example symptom: reduction in resting heart rate).
If you do a lot of one, find your performance dropping then it is good to spend some time doing the other. With high intensity based training this means doing relaxing low intensity activities.
Really I shouldn't get overtrained with what I do in the gym it is just the outside pressures that lead to this.

So, it doesn't mean you're paraletic and you want us to be sympathetic then?
