Then what other HIIT exercises that I can try? Other than running?

@Kasey Brown, so should I do crunches, overhead presses, front squat or HIIT or..all? XD

hey, does doing core exercises (such as "the plank") help reduce flabs around the tummy faster than normal?

There's no such thing as spot reduction (losing fats targeted at one area). When you do exercises, your body will determine where the fats will be burned from.

The human body has been proven to actually be capable of spot reduction, by controlling hormones. Hormones and genetics happen to be the reason why women have bigger hips and males have bigger stomaches, why some men have gynecomastia while some females have a more manly feature, thus it only makes sense to control these fat controlling hormones.

Okay, simple science aside...

The butt/glutes is sort of like a "toxic" marker in the body. The higher the level of toxic in the body, the higher chances of storing fat in these areas. Thus in order to reduce fat in the glutes, is to reduce the level of toxics in the body.

Also certain movements such as cycling, spinning or jogging actually cause you to store MORE fat around the gluteal areas, as a quicker energy source for the body. Just take a look at joggers. Notice how their bodies seem to be very, pear'ish? The increased stress from all the pounding from running, doesn't help either.

It's likely that you'll get better results from a combination of a bilateral and unilateral circuit, lower body weighted exercise with high repetitions and low rest time would work better. Also reduce toxicity levels with clean eating.

Really??
Spot reduction, can happen. However, not in the way we used to believe. It's by controlling your hormones, with supplements and rest and certain dietary changes.

You should get someone to write you out a workout program.

sit ups =/= ripped abs. Clean diet = ripped abs.

define clean diet. 

are u somewhat being skeptical / sarcastic?

What shiloong7081 said is right, CLEAN DIET is the way to six pack abs. U need to work the way down to single digit bodyfat% to bring out the abs muscles.

Working out in the gym is just 30-40% , the rest is from your daily diet.

no one says you can't eat fried food, you can. Only thing is, fat has more calories/g compared to carbs and protein and less volume. So you won't feel as full, and eat more.

Am i getting this right ?
