Sorry about my thread title, it's really hard to explain.
I have been going to the gym 3 or 4 times a week and doing exercise at home ( gentle exercise ), before I started going to the gym I was pretty lazy and unfit.
Anyway, when I eventually get to lie on the sofa in the evenings I am getting this weird feeling in my legs and arms, almost like something heavy is on top of new, like I can't move or my arms and legs are heavy. Is it just due to using new muscles? Or something else? It's a very weird feeling.
