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

Key strategies for strength + hypertrophy (and why they matter)

• Strength & hypertrophy are essential for longevity and function, not just aesthetics or athletic performance.
• Neuromuscular aging defense: Resistance / “heavy overload” strength training is presented as the primary way to combat neuromuscular aging.
• Preserve strength & especially power: Aging often causes larger declines in strength and muscle power than in muscle size. Maintaining these supports real-world abilities like standing, moving confidently, and recovering from falls.

Self-care / behavior principles that drive results

• Consistency beats intensity
  • Adherence is described as a top predictor of fitness outcomes.
  • Choose a plan you can repeat reliably over time.
• Progressive overload is non-negotiable
  • If you don’t continually add stress (load/volume), adaptations plateau.
• Individualize within a structured framework
  • Adjust based on equipment, preferences, biomechanics, and what’s realistically sustainable.

“Non-negotiables” of an effective strength & hypertrophy program

1. Consistency (adherence)
2. Progressive overload
3. Individualization (equipment availability, preferences, body constraints)
4. Target selection + smart specificity/variation
   • Enough specificity to produce progress
   • Not so much variety that you lose long-term training direction
   • Not so much variation that you raise overuse injury risk

Core idea: exercises don’t determine results—execution does

A movement only improves the target quality if you perform it correctly with the right intent and execution quality.

• Example: a deadlift won’t increase strength unless executed properly (not just “doing deadlifts”).
• Example: box jumps only improve power if you perform them powerfully (not casually).

Practical programming “starter template” (strength/power oriented)

• The “3 to 5” rule
  • 3–5 days/week
  • 3–5 reps per set
  • 3–5 sets per exercise
  • 3–5 minutes rest between sets
  • High intent is critical
• Progression target
  • Aim for roughly ~3–5% increase per week, mostly via load (intensity).

Repetition cadence guidance (strength vs hypertrophy)

Strength training

• Strength = ability to produce force and move weight.
• Don’t intentionally slow down to “learn slower” if the goal is strength—slowing reduces acceleration and therefore force production.
• Emphasis: practice producing force quickly (lift heavy with intent).

Hypertrophy training

• Hypertrophy = increasing muscle size.
• Cadence is more flexible; you can use different tempos as long as you still achieve the required stimulus (volume, proximity to failure, etc.).
• A noted tool: time under tension (e.g., slower eccentrics or holds) can substitute when load is limited.

How to choose exercises (strength/power and hypertrophy)

Strength/power “choice” preference

• Prefer compound movements and movement patterns (not only single-muscle “body-part” targeting).
• Suggested pattern coverage:
  • Upper + lower
  • Push + pull
  • Include some rotation work for longevity/wellness balance

Hypertrophy exercise selection

Hypertrophy can be achieved through many styles, but it works best when you:

• Train the muscle with sufficient hard work
• Ensure the stimulus is actually applied to the intended muscle

Key recommendations:

• Include both bilateral + unilateral work
  • Bilateral: squats/presses with two legs
  • Unilateral: split squats, single-leg presses/curls, pistols, etc.
• Machines can help isolate
  • If a barbell movement isn’t producing growth in the target muscle (e.g., quads not responding), adjust technique or use machine isolation to better target the muscle.

Volume targets for hypertrophy (muscle growth)

• Minimum: ~10 working sets per muscle group per week
• More realistic: 15–20 working sets/week
• Advanced: may push toward ~25 sets/week
• Reps proximity to failure
  • A suggested guideline: stop around ~2 reps in reserve (RIR) (not necessarily full failure).
  • If a set feels easy (far from failure), you may need more effort, or adjust reps/sets.
• Time-crunch adaptation (“chaos management”)
  • ~10–50% of workouts may be disrupted in real life.
  • If short on time:
    • Hypertrophy: reduce load/rest, but still accumulate the needed volume
    • Strength: cut volume (even by half) while keeping work high-load and high-quality

Frequency and workout structure (what matters most)

• Frequency matters less than total weekly volume and your ability to train near the needed intensity/failure level.
• Many people benefit from resilient schedules because missing sessions is common.
  • Recommended: ~3 days/week total body for adherence resilience
  • Alternatives:
    • 2 days/week total body + 2 days/week with some body-part focus
• Caution with “once-a-week legs”
  • Legs contain multiple muscle groups; one leg day risks under-dosing weekly volume and creating upper/lower imbalance over time.
