Alright I'm 5'11 and I weight 360lbs. I am sick of being fat and I think I have mastered not over eating. Now I need some excercise tips for beginners. I'm trying to see how long it will probably take me to lose 100 lbs. How should I start off my excercises at home? No gym right now because I'm too embarrassed to work out in front of people. :-(
