GUEST SERIES | Dr. Andy Galpin: Optimal Protocols to Build Strength & Grow Muscles

Dr. Andy Galpin, a kinesiology professor and exercise science expert, shares fascinating insights on building strength and muscle. He discusses optimal training protocols, explaining the difference between strength and hypertrophy while emphasizing the importance of resistance training for longevity. Galpin delves into effective exercise techniques, nutrition, and the role of recovery in achieving fitness goals. He also provides actionable advice on overcoming plateaus and optimizing training frequency to enhance power and performance.

Strength training: the anti‑aging tonic

Strength work is the #1 tool to fight neuromuscular aging. It preserves motor units, strength and — most critically — power (which drops ~8–10%/yr).

Do it at any age: even people in their 90s see huge gains in 12 weeks.

If you have a body, you're an athlete.

Strength vs. Hypertrophy — not the same thing

Strength = force produced (function + mechanics + neural skill).
Hypertrophy = muscle size (myosin/actin & sarcoplasm).

You can get stronger without getting much bigger (neural, contractility, fiber type, pennation). Conversely, bigger muscles often add strength but aren’t guaranteed to optimize performance.

The simple 3–5 rule for power & strength

Use the “3–5” heuristic: 3–5 days/week, 3–5 exercises, 3–5 reps, 3–5 sets, 3–5 minutes rest.

Power: use submax loads (30–70% 1RM) with max intent to move fast.
Strength: generally >70% 1RM; still attempt max velocity and prioritize quality reps.

Breathing & brace: Valsalva done right

Use air to create intra‑abdominal pressure — a cylinder around the spine — while still breathing. Inhale before the eccentric, brace, then exhale during/after the concentric if needed.

Rule: brace + breathe. Avoid locked‑diaphragm blackouts; release slightly to let blood flow between max efforts.

How to make muscle grow: 3 routes

Hypertrophy can be driven by:

  • Mechanical tension (heavy sets),
  • Metabolic stress (pump / high reps / blood‑flow restriction),
  • Muscle damage (not required).

Make the signal loud or frequent. Protein + carbs around training help the process; choose the route that fits your schedule.

Practical volume & rep targets

Aim ~10–20 working sets/week per muscle (15–20 ideal for many).
Rep ranges: 8–15 is classic for hypertrophy; 4–8 mixes strength+size; 30+ can work but is less practical.

Get close to failure (2 RIR = reps in reserve) on most sets; vary tempo/rest to manage recovery.

One go‑to supplement: Creatine

Creatine monohydrate is the top evidence‑backed supplement for strength, power, hypertrophy and even some cognitive/bone benefits.

Typical dose: ~3–5 g/day (scale with body size).
Timing: irrelevant — take when you prefer (post‑workout shakes are common).
