OK didn't know here else to post this, is kinda related to fat loss, as it's impeding it, heh.
I'm 27 years old. Ive been weight training since 18, with a few on and off periods. I have a nagging pain in my lower back and occasionally shoulders. But don't have anything serious enough for a doctor to have taken seriously (certainly not a sharp pain) I'm trying to lose weight fast. I'm at a pretty big calorie deficit, but I really don't care if i lose some muscle too, I am sick of being flabby nowadays.
I'm weight training 3 days a week (not pushing too hard) and doing an hour of pretty hard running on the treadmill another 3 days a week.
Yeah that's fine.
However I'm pushing myself a bit more than that. after either the weights or the running, I try to do another 3 hours of gentle cardio (I have audiobooks, I figure I may as well read it whilst exercising rather than sat down) I either go on the treadmill or the elliptical cross trainer thingy. If i walk more than an hour, I start getting a very annoying dull ache in my hips.. and the cross trainer hurts my lower to mid back for a day.
This is only additional GENTLE exercise though, I am only 27. Is this normal? How the hell do people train for marathons? I heard of swimemrs doing many hours a day etc.
Am I just injured, or just getting old? Thanks.
