Frequent episodic bouts of resistance exercise combined with protein ingestion result in skeletal muscle hypertrophy, primarily by driving increases in muscle protein synthesis (MPS) rather than changes in muscle protein breakdown (MPB).

To build muscle, you need to combine resistance training with protein intake. This combination works by significantly boosting muscle protein synthesis. Don't focus solely on the immediate post-workout spike; consistent training and protein consumption over time are what drive actual muscle growth.

GoodSupportsHIGH confidence
Frequent episodic bouts of resistance exercise and protein ingestion result in skeletal muscle hypertrophy [6]. It is important to acknowledge that in many instances it is the alterations in MPS, and not MPB, that are the focus of many investigations [7–10].

Why this rating

Based on a review of multiple human studies and established metabolic principles, though specific dosing protocols are discussed as variable.
