What is the best excercise for your belly and love handles?

You cannot spot reduce fat. Your body will loose the fat all over your body by exercising and eating better. I am sure you already know this, but I just have to say it, because I feel that so many people still think you can get a smaller waiste by doing abdominal exercises alone.

You should do the exercises, of course, but don't assume this will make love handles go away without changing your diet and adding cardio and weight training for all your other muscle groups.

I do crunches, cable crunches with high resistance for 2-3 sets at 12 max reps per set
and leg raises for my lower abdominals.

Hope this helps!
