You cannot spot reduce any specific area without surgery. While running may tighten and strengthen your legs and calves - and pushups will do the same for your chest, neither will spot reduce. You must exercize, exercize, exercize!! - Also, muscle is metabolically more active than fat - I know you said you don't want to touch weight equipment - but increasing your muscle mass slightly will boost your metabolism so your body will burn fat quicker. Liposuction is the only way to spot reduce. Women tend to loose weight/fat from their breasts first, so that would help you out in the one area. Unfortunately though, thighs-buttocks,and legs are the last and hardest place for women to shed the punds.
