If you spend more than 2 or 3 hours a day on technique, you will injure yourself.
It is not physically impossible to practice for 10 hours a day......and you won't get injured if you practice more than 2-3 hours.
2-3 hours straight playing with complex stuff sure, but you can always do simpler stuff. I've done it many times.
