In my quest to be thinner I have found a great way to increase my metabolism, and it will work for you too. When you hit the treadmill, instead of just walking or running do both! Run three minutes, and walk three minutes. Do that on and off for about 30 minutes. You will be shocked at how quickly you will start shedding inches in your middle and around your hips. This hip tip will get you that much closer to your perfect bathing suit bod.
