Tempo in the Gym: Science Finds Reps Speed Does Not Change Muscle Growth
A new wave of exercise science suggests that how fast you lift may not matter for building bigger muscles, so long as you do enough work. In the latest take on rep tempo, researchers say slow or fast repetitions yield similar muscle growth when total training volume and effort are matched. For busy Thai adults juggling work, family, and social life, the finding could be a practical nudge: you don’t need to chase a single tempo to unlock gains; consistency and progression matter more.
