Healthy weight range depends on your height and body composition. Use BMI as a rough guide (18.5-24.9). But muscle weighs more than fat, so athletic men may be "overweight" by BMI yet healthy.

Combine both. Strength training (3-4x/week) increases metabolism and muscle. Cardio (150-300 min/week) improves heart health. Together: better fat loss and overall health.
