How much cardio do you need to do per day to lose belly fat?

How do you know if you’re gaining muscle?

Track muscle gain through multiple indicators: increased strength in your exercises, improved muscle definition and firmness, better-fitting clothes (tighter in muscle areas), progress photos showing visual changes, and body composition measurements.
