Ok, I use to do vocals daily, for around 3 hours at a time, then I got a job, and never had much time, so I put them off for around 2 years or less. (Still with occasional vocal work)

But now, I've learned to manage my time, and vocals, but I sound like shit. I'm trying to re-gain my vocals, Death Metal lows, and work my way up. Currently the bands I cover are Cannibal Corpse, Deicide, and Bloodbath.

I sound like SHIT. It's probably because I've stopped for so long, would it be easier to start off with something easier than the stated bands? or should I continue with this, and simply take my time.

In the 2 year hiatus, I started smoking, and now with me starting my vocals up again, I'm giving that up, would it be wise to do crunches and sit ups to strengthen my abdomen so I can get a stronger sound from my vocals? Also, I plan on drinking plenty and keeping myself hydrated.

Any tips, advice, comments, insults, concerns, motivation, or something?

Thanks and sorry for the long post.
