Very difficult to give precise answers to this sort of qustion as it would depend on several things e.g. Your basal metablolic rate General level of physical activity in your lifestyle Calorific consumption whilst training Sex (male or female not "frequent") Current fat levels Physical Build Genetics Age Hormone levels (including insulin and testosterone) Use of drugs including caffeine and alcohol You can't use situps to spot reduce abdominal fat. It's a common myth. Cardio is unlikely to do it either. Men, unfortunately, have a built-in tendency to store fat round the stomach area. Women along the hips and thighs. This is by design to aid survival in a hunter-gatherer environment where one may not know when the next meal might arrive. The modern neolithic diet (farmed) based on grains and high carbs isn't really conducive to the way human physiology evolved. We were designed as surival machines able to cope with extreme lifestyles. A life lived on burgers, cakes, bread and cola isn't really too compatible. The incompatibilities become more extreme as one gets older and the body becomes less tolerant of excesses. You'll need to calibrate your diet to the way your own body works. Cut down on carbs (the popular notion of fats being the culprit is a politically-inspired myth). Cut down on your helpings generally. Eat smaller portions, more frequently. Become more active throughout the day. Power walk rather than stroll around. It is important to keep a good quality diet if you are training whilst trying to reduce fat. Recent research underlined the fact that the body consumes muscle before it starts to consume fat where exertion is high and diet is insufficient. Thus, if you're not careful you may wreck training efforts and lose nothing off your waistline. Most bodybuilding mags have good coverage of this subject.

i think u should do cardio before you hit ur abs. Maybe a 30 minute run , or a treadmill. Jumprope is good too.

most important is a good diet. Try to get an hour of cardio at least 3 days a week. splitting time into 2 30min sessions per day. Also dont count your situps let your abs tell you when to stop they need to be exhausted. You can also do ab twists, pull ups, hanging leg raises, and other ab exercises. If you have the same routine everyday your body gets used to it. Try switching it up every month or so. Results come little by little.

kind of depends on your natural body shape. I usually keep most of my weight on my lower body on my butt, hips and thighs. I hardly keep any weight on my midsection. When I attempt to lose weight from my midsection, it's not too difficult but when I attempt to lose my stubborn thigh inches, I exercise and exercise but get nowhere. I've also found that cardio seems to do me more inch burning good than any sort of strength exercise. I used to do a lot of squats and got nothing but I just played DDR for a week and I lost a good 1 1/2 inches on each thigh.
