I find that when I really push myself, my body doesn't reward me.
This occurs usually only when I am doing upper body workouts.
I feel like I am pushing myself and I can really feel my arms burn. When this happens, I sometimes decide to cut my workout 1 or 2 sets short because, even though mentally I feel I can do it, which makes me want to do it for the sake of pushing myself, I have had enough of these experiences that I know to stop anyways.
Then, about 1-2 minutes later, when I sit down and drink some water, I am thanking my lucky stars that I didn't do it, because I feel ridiculously tired and nauseous for 5-15 mins.
Is this normal or am I dehydrated or something?
Why is it that I feel like I can do anything as I am contemplating it, but its only afterwards that my workout catches up to me.
Feel free to tell me if I'm just being a b**** and it's normal. I just don't want to inadvertently hurt myself as a result of trying to become strong.
