Lean muscle mass refers to the amount of muscle on your body after subtracting fat. It's the portion of muscle that is free of intramuscular fat.
Having more lean muscle:
Helps boost your metabolism. Muscle tissue burns more calories than fat tissue, even at rest. The more muscle you have, the more calories you burn.
Supports fat loss. By increasing your metabolism, more muscle allows your body to tap into fat stores for energy.
Strengthens your bones. The pull of muscle on bone promotes bone growth and strength. This can help prevent osteoporosis.
Improves your strength. Muscle contributes directly to strength capability and physical performance.
Enhances athletic performance. Greater muscle power, strength, and endurance can boost sports performance.
Contributes to injury prevention. Strong muscles help support joints and provide shock absorption.
How to Build Lean Muscle Mass
Follow these key evidence-based strategies:
Resistance train. Lift weights or do bodyweight exercises like pushups and squats. This is the most direct way to build muscle. Shoot for at least 2 sessions per week.
Eat sufficient protein. Get 0.5-1 gram of protein per pound of body weight per day to support muscle growth. Foods like chicken, fish, eggs, and Greek yogurt are great sources.
Allow muscle recovery. Take at least 1-2 rest days between resistance training sessions to allow your muscles time to recover and grow.
Sleep adequately. Aim for 7-9 hours per night. Growth hormone is released during sleep to facilitate muscle growth.
Manage your stress. Chronic high stress can increase cortisol which may impair muscle building.
Include steady state cardio. While HIIT is great for fat loss, steady pace cardio helps deliver nutrients to muscles.
Stay consistent with your exercise regime and diet focused on lean proteins and vegetables. Be patient, as muscle growth occurs gradually over weeks and months of strength training. With dedication to your muscle building goals, you'll gain strength, support fat loss, and improve your overall fitness.
