Q: Kimberly, I'm 16 years old and started working out seriously this summer. But with my school and job schedule, I can't fit in workouts. Will my hard-earned muscle turn to fat?
A: The good news is that, no, your muscle will not turn into fat. Muscle cannot turn into fat.
But your muscles will shrink and you'll lose a significant amount of your strength if you go too long without exercising. Try to squeeze in just 15 minutes of strength exercises daily. That should help a lot.
