Strength Training vs Cardio for Weight Loss

🔥 Which Burns More Fat?

• Cardio burns more calories during the workout.

• Strength training burns fewer calories during exercise—but increases calorie burn for up to 48 hours after (afterburn effect).

📌 Winner: Strength Training (long-term fat loss)

Why? Muscle increases your basal metabolic rate, meaning you burn more calories even while sleeping.

Strength Training vs Cardio for Muscle Building

If muscle tone, strength, and body shaping are your goals:

• Cardio helps endurance but does not build muscle

• Strength training directly targets muscle growth and definition

📌 Clear Winner: Strength Training

Strength Training vs Cardio for Heart Health

Cardio has long been known for improving heart health, but strength training also plays a role.

• Cardio lowers blood pressure and improves circulation

• Strength training improves insulin sensitivity and cholesterol levels

📌 Winner: Cardio (with strength as a strong support)

Which Is Better for Beginners?

For beginners:

• Cardio is easier to start and requires less technique

• Strength training offers faster body transformation if done correctly

📌 Best Option: Combine both
