Ever wonder why the weight won't budge from your hips and thighs? You didn't make it up, there a reason those last few pounds are the hardest to shed. It isn't lack of effort, it is homeostasis. Celebrity trainer Holly Perkins says that all of your body systems work together to create a "happy, cozy, and unchanging" environment. You body is fine tuned to maintain the status quo and so when you are committed to changing your lifestyle, you best be prepared to be uncomfortable. You body is going to fight you on it. Even after you've made all the necessary changes and started reaping the rewards of being fit, you will hit a weightloss plateau. Bad news is that it is more difficult for women to take off weight from certain places. Metabolism investigator at the University of Texas Southwestern Medical Center Deborah Clegg explains, [Women] fight against losing weight in our hips and thighs. And the reason we're programmed that way is that we rely on the calories in our hips and thighs evolutionarily to provide us with calories for breastfeeding or to help sustain a potential famine while we're pregnant." Although it may be frustrating, it is at least a good reason. The trouble zones for women seem to be hip, thighs, glutes and abs -- all places biologically predisposed for reserving fat that also have a lot of muscle that goes unactivated. Strength training boosts your metabolism and helps build strong muscle underneath these trouble zones making the fat appear leaner. The thing is, you won't be able to reduce these areas quickly but strengthening them can only make you feel stronger and more confident. You will know you're successful when you can slip into those jeans you've been dying to wear! How do you deal with your frustrations?
