I didn't work out the last 5 years to my regret. I had a ski accident and my back hurt severely the previous 2 times. I changed my behavior again, i was working too much to actually "want to do/start it". I'm at 3 hours per day ATM. ( Back seems to be ok! ). Next step is to change to weight training and reduce the amount of hours, since the current slow-paced cardio phase is not sustainable. But i hope it helped me for my back as a transitioning phase...
