In this concise fitness explanation, Eric Roberts addresses the common question of whether post‑workout soreness is necessary for muscle growth. He outlines three primary reasons muscles become sore: (1) micro‑tears caused by mechanical stress during lifting, (2) inflammation that follows that stress, and (3) novel exercises that challenge muscles in unfamiliar ways. Roberts then clarifies that none of these soreness mechanisms directly cause hypertrophy. Instead, muscle building depends on progressive overload—consistently lifting heavier loads, increasing repetitions, and training close to muscular failure. Consequently, whether you feel sore or not, as long as you apply these overload principles, you will stimulate muscle growth.
