How Many Calories Does Strength Training Burn?

Quick Answer: Strength training burns approximately 175-630 calories per 30 minutes for a 70kg (154 lbs) person, depending on training intensity. Light effort burns ~123 calories, moderate training ~175 calories, vigorous powerlifting ~210 calories, bodybuilding ~245 calories, circuit training ~280 calories, and CrossFit/HIIT strength training ~315 calories per 30 minutes.

Strength training is one of the most effective forms of exercise for building muscle, increasing metabolism, and burning calories both during and after your workout. Unlike steady-state cardio, strength training creates an "afterburn effect" (EPOC - Excess Post-Exercise Oxygen Consumption) that can elevate your metabolism for 24-48 hours post-workout.

Factors Affecting Calorie Burn

  • Training Intensity: Higher intensity workouts with heavier weights and shorter rest periods burn more calories.
  • Exercise Selection: Compound movements (squats, deadlifts, bench press) burn more calories than isolation exercises.
  • Rest Periods: Shorter rest periods increase calorie burn and cardiovascular demand.
  • Training Volume: More sets and reps increase total energy expenditure.
  • Body Weight: Heavier individuals burn more calories performing the same exercises.
  • Muscle Mass: More muscle mass increases resting metabolic rate and calorie burn.
  • Workout Tempo: Controlled, slower tempos can increase time under tension and calorie burn.

Benefits of Strength Training

  • Increased Muscle Mass: Building muscle increases your resting metabolic rate, helping you burn more calories 24/7.
  • Improved Bone Density: Resistance training strengthens bones and reduces osteoporosis risk.
  • Enhanced Metabolism: The afterburn effect keeps your metabolism elevated for hours after training.
  • Better Body Composition: Strength training helps reduce body fat while preserving lean muscle mass.
  • Functional Strength: Improves daily activities and reduces injury risk.
  • Mental Health: Regular strength training improves mood, reduces anxiety, and boosts confidence.

Training Recommendations

For optimal results, aim for 2-4 strength training sessions per week, targeting all major muscle groups. Beginners should start with 2-3 sets of 8-12 repetitions per exercise, focusing on proper form. As you progress, you can increase weight, volume, or intensity to continue challenging your muscles and burning calories.

Combine strength training with cardiovascular exercise and a balanced diet for comprehensive fitness and weight management. Remember, the best workout program is one you can stick to consistently over time.
