You Can Spot-Reduce Fat
Just like how endless crunches won't give you a six-pack, doing thousands of bicep curls won't automatically make you lose arm fat and lunges won't do anything to target the fat on your thighs.
"Simply put, you cannot spot-reduce pounds from any given region on your body," Corey Phelps, NASM-certified trainer, explained. "Just as you cannot influence where your body stores dreaded excess fat when it packs it on, you can't control where your metabolism opts to pull from when it taps into fat stores, which incidentally tends not to be from the region we gain it in the first place. When it comes to burning fat, a total bodyweight lifting program and clean-eating plan are your best bet."
You need to lose fat overall to see progress on any specific body part. This requires eating in a healthy calorie deficit and balancing cardio and strength training.
