I would say... cardio and what you're putting into your body.
All the exercise in the world won't do much for fat-reduction. It WILL firm up your muscles, but you'll hardly see them unless the fat is gone!
Cardio (anything from walking to running to cycling/spinning to aerobics class) speeds up the heart beat and allows the fat to be "burned" off. And the less fat your put into your body, from food, the less there will be on your body.
Two years ago I picked up Susan Powter's 'Stop the Insanity'. I couldn't put it down! Yeah, she can be pretty forward but I feel that what she says is really good! She doesn't count calories or grams of fat. That's too tedious. Instead she counts PERCENTAGE of fat. From what I've garnered from her book and her interpretation of the ongoing trend of how much our bodies actually need... In order to maintain our weight, we should eat no more than 30% fat. If we want to decrease the fat on our bodies, then we decrease how much we PUT IN--down to 20%.
It's actually quite easy to do and SO MUCH MORE simpler than counting calories/grams of fat and limiting our meals.
|Grams of Fat X 9 (9 calories per gram of fat) / number of calories.
So... if something has 5 grams of fat and 130 calories you'd do this:
5 X 9 = 45
45 / 130 = 0.346 You multiply that by 100 = 35% fat.
ONLY 5 grams of fat you say? Yeah, but it's a whopping 35% fat! That might be fine, as long as you don't eat like that all the time.
I did what she said, did Yoga in the mornings (Baron Baptiste style--does stretching AND cardio AND strength); and weight training three times a week. In five months I went from 160 lbs to 135 lbs and I looked GREAT! Because the fat that I lost was replaced with muscle, hence the not 'great' weight loss. But I was leaner!
(We won't talk about the depression that stopped it all and had me balloon up to 170 lbs! )
So.... in short: cardio and nutrition is what I would suggest. For now.
