The Differences Between Training for Size Vs Strength

Summary by Krater

Dr. Mike Israetel from Renaissance Periodization explains the key differences between strength training and hypertrophy (size) training, covering loading, volume, progression, frequency, and exercise selection, and offers guidance on how to combine both goals.

Answers: What are the differences between strength training and size training and how can you do both?

• strength training vs hypertrophy training
• loading differences
• volume differences
• progression differences
• frequency and undulation differences
• exercise selection differences
• concurrent hybrid training
• phase potentiation

What it concludes

• Basic strength is best increased in the 3 to 6 rep range, while overall hypertrophy is best increased in the 5 to 30 rep range.
• Strength training is more fatiguing per set and requires higher preparedness than hypertrophy training.
• Progression in strength training relies heavily on loading progression, whereas hypertrophy training relies on volume, load, and sets.
• Hypertrophy training allows for higher training frequency because local muscle recovery happens faster than full connective tissue and neural recovery required for heavy strength work.
• Strength training requires multi-joint compound free-weight exercises with high stimulus-to-fatigue ratios, while hypertrophy training can benefit from a wider variety of exercises including machines and isolation movements.
• Advanced lifters must use phase potentiation or dedicated hypertrophy and strength phases to get the best of both worlds, whereas beginners can build both size and strength using sets of 5 to 10 reps.
