I have a very busy job and would love the time to exercise during the day but I don't, and the thought of getting on a hard floor to do sit-ups puts me off! I'm something of an insomniac and am most alert at night, and when I'm lying in bed it's the perfect time to exercise for me... but is it ok to do so on a mattress? I've never heard anything regarding this before, but I know the norm is a hard floor...
And I'm not talking sex, I mean sit-ups, leg raises etc... is there any harm involved, i.e. to my back or anything?
