How much is too much?
I've been on my diet for about 3 months now. I've lost 60 lbs and I'm feeling pretty good. My latest concern has been the difference between "feel the burn" and "oh crap I hurt something". I just can't seem to figure out if what I'm doing is right or wrong.
Let's say I'm walking and doing jog sprints and my leg starts hurting. Is this ok because I'm working out, or should I slow down because I'm damaging my body? I'm so confused it is even hard for me to explain, but any advice is much appreciated!
