Excess fat on the belly, upper arms and inner thighs doesn’t typically occur in isolation. If you’ve got it there, chances are you’ve got it everywhere. You can’t spot reduce. No exercise will target fat cells in just one part of the body. You need to target them all via exercise and proper nutrition. And if you really want to see muscle definition once the layer of subcutaneous fat is shed, make sure you’re following a strength training program designed for building muscle.
