Muscle

Your metabolic engine. Muscle is far more than movement—it's an organ of metabolism, glucose disposal, and longevity. Muscle mass declines with age but this is not inevitable. Strength training and protein are foundational for healthy aging.

Why Muscle Matters

Glucose Disposal

Muscle is glucose sink. More muscle = better blood sugar. Prevents insulin resistance.

Metabolic Rate

Muscle burns calories at rest. Lose muscle = slower metabolism. Age-related weight gain.

Bone Health

Muscle pulls on bone. Stimulates bone density. Prevents osteoporosis.

Fall Prevention

Strength and balance. Leading cause of death in elderly. Preventable with training.

Immune Function

Muscle releases myokines. Anti-inflammatory signaling. Immune reservoir.

Longevity

Grip strength predicts lifespan. Sarcopenia is deadly. Muscle is medicine.

Building & Maintaining Muscle

Resistance Training

Stimulus for growth. 2-3x per week minimum. Progressive overload.

Adequate Protein

1.6-2.2g per kg for building. Essential amino acids. Leucine trigger.

Protein Distribution

30-40g per meal. Spread throughout day. Don't skip breakfast protein.

Recovery

Muscle builds during rest. Sleep is critical. Avoid overtraining.

Compound Movements

Squats, deadlifts, presses, rows. Multiple muscle groups. Functional strength.

Consistency

Gains are slow. Years not weeks. Maintain what you build.

Nutrients for Muscle

Creatine

Most researched supplement. Strength and power. 5g daily. Safe long-term.

Vitamin D

Muscle function and strength. Deficiency causes weakness. 40-60 ng/mL.

Magnesium

Muscle relaxation. ATP production. Prevents cramps. Most are deficient.

Omega-3

Muscle protein synthesis. Reduces inflammation. 2-3g EPA/DHA.

HMB

Leucine metabolite. Prevents muscle breakdown. Useful for elderly.

Zinc

Testosterone support. Protein synthesis. Lost in sweat. Athletes need more.
