my sinews bitching on me

I've been going to the gym lately, I've done that quite before, but since my graduation I just went occasionally and irregularly. after 5 times I might say that the will is forcing me to go, but still I have a lot of work to do. My muscles seems to be very week, and it's like striving with the weights. My food pattern is still blown up. I don't eat healthy and I eat mostly out, but my willpower is just letting me do it! I should just do it! just one of my dear friends told me! I'm week but I will be strong enough I need to move that huge stone inside of me!
