How often do you wake up tired and sore?

for me the past few days have been the same. wake up with sore stiff muscles. goes away after a while though. just thinking my bed is just a pos. its about 10-12 years old. never wake up feeling refreshed. heat could have something to do with my sleep as well I figure. past few days I've been doing my cardio in the evenings as well.
