The second step was to start the exercises, since I was more than half way to achieving my goal, this was more fun than I thought. I started off slow and increased as my fitness levels got better. I now exercise three days a week using mainly the exercises in Mike's book, I also do a little strength training like pull ups and tricep extensions just to boost my muscular strength. I have been doing so for only two months and have had great results, I have not got a six pack stomach as yet, but my stomach is flat and I am so confident that it is only a matter of short time since all the hard work has been achieved to get rid of the bulge I once called a stomach.
