ImFocused MeltDown Training Log

Ok i have decided to keep a log of my meltdown training and T-Dawg Dietjust so i can stay motivated and get feed back from all the great guys on this forum.I am getting married in a year and my goal is to get down to 250 and see how i look and go from there. a lil history on me is I once weighed 360 got down 283 with the abs diet and 2hrs of cardio a day. but i still didnt like how I looked with my clothes off. so I moved to texas and have let my self go a bit I pretty much had lost the disipline I had before but im back and am focusing more on weight and less on cardio which is why i loved the MeltDown because it allows me to still pump iron and burn at the same time plus i keep hearing such good things about circuit training.

my stats:
Weight 322
Heigth 6’2
BF 37%
Calorie intake 2700 Attached a pic of my nutrition breakdown
