I found that the only way to rid myself of my beer gut was to do sit-ups or crunches. After a great deal of effort doing cardio exercise for half an hour daily, followed by strength training for another half hour, I was losing weight and did look better, but my gut still had this mid-line bulge that I could not get rid of. After some more research I came to the conclusion that I needed to try abdominal crunches. I started out doing ten crunches a day, then gradually increased the number of sit-ups until I worked up to 150 per day. I can complete 150 crunches in about ten minutes, so it didn't really add much time to my workout. I learned that sit-ups or crunches, are vital to work your core, and the only way to reduce the size of the belly. I use a sit up machine where I sit in a chair and pull down with a cable from behind my head. There are other sit up machines where you sit in a chair and push down on a padded bar against your chest. I don't like simply doing sit-ups on the ground lying on my back, as this hurts my 50 year old back. Give sit ups a try and see if it works for you.
