Do I need to do ab excersizes to cut my belly fat?

Adding ab exercises would help you lose weight and become healthier faster. I would suggest trying different work out videos. Crunches don't do all that much in most situations. Try doing an exercise called a plank. Also try doing hollow holds. These are both great exercises and commonly known. I use a video called hip hop abs with Shaun T. It works really well, and I got it off eBay so I didn't pay too much. Another thing you might want to check is your posture. If you slouch, it can cause you to look like your lower stomach is bigger than it is. Make sure to stand straight and that might help to. Good Luck:) I hope this helped!
