It seems every time i start to work out consistently (mostly when I'm including push-ups/crunches/squats)
My workout gets more and more tiring and it keeps getting worse till i dont have the energy to workout any more.
I eat fairly well and sleep average of 8 hours / day i'v tried sleeping 7 8 9 10 and even 11-12 hours and it doesn't help me restore the energy i once had just gives me a big headache if i sleep over 9 hours
I'm only 18 so I should have lots of energy but sadly i feel really drained! and nearly all the time!
EDIT: i workout 5 days MTWRF / week with the day on day off / muscle group method
Any suggestions would be greatly appreciated! thanks!
