How can you reduce bulky ab muscles I was overweight and constantly tense and train my ab muscles now i have bulky abs rather than lean ones How can i make then leaner and flatten my stomach?

The bulkiness of your muscles has nothing to do with the workout. It has everything to do with your eating habits. If you want a lean look then cut out carbs from your diet and use a good protein supplement which has Whey Protein Isolates. These are easily absorbed in your body and can give you that lean look. Work out as much as possible.
