As a 5'11", 200 lbs male, your estimated lean body mass is 145lbs. This means you are currently at ~27% body fat.

In order to get a six pack, you will need to drop about 29 lbs of fat. The actual number will be less if you already have a decent amount of muscle on you, but we'll roll with this number for estimation purposes.

Keep in mind that your "target weight" is irrelevant. On our suggested program (as with any legit fitness program) you will gain muscle weight.
