headaches usually result from poor blood circulation due to either
A) your weight problem
B) smoking - ( i knew a co-worker that suffered from this)
c) both
just remember to drink more water regularly whether or not you're hitting the gym as it helps to dilute the blood and flow easier.
on the going to the gym part, join if u truly desire to workout.
if your body is feeling like crap, and your brain says go for it, but u wont nudge, then u cant do anything about it unless both agree.
i had a skinny friend that signed up for a one year contract which was $500 last year, he went once with me, after that he didnt go at all and all the money down the drain.
then i had this other friend who wanted a 1 week trial, i got him to go w/me since he was begging me to help him out, fix his gut and lose weight. But he was only willing to go that 1 time, if i wasnt there he wouldnt dare going. we got there and i briefed him which exercises are for abs, instead he just went about trying every machine.....so that was his first time and probably the last time he went to my gym.
honestly i dont even know why these 2 guys even considered working out when the motivation wasnt there in the first place...
don't be like those guys, either u join and follow a strict workout program, or you dont join at all. cause you'll just be wasting money and time if you dont follow a routine workout schedule.
