Most people chasing fat loss do more cardio — longer sessions, more miles, harder effort. But the exercise that moves the needle most may be the one they're skipping.

What you'll learn in this video

  • Why "just do more cardio" is the most common fat-loss mistake — and what the metabolic picture actually shows
  • How muscle acts as a metabolic engine that uses energy even at rest

  • Why resistance training may protect fat-loss results in a way steady-state cardio can't
  • How insulin sensitivity and body composition are linked — and which kind of training tends to matter most
  • Why this gets more important after 40, when the body defends fat more stubbornly
