After gym muscle pain, also called delayed onset muscle soreness (DOMS), is the stiffness or tenderness felt 24-72 hours after intense exercise. It occurs when muscles repair microscopic damage from exertion.

How After-Gym Muscle Pain Works

DOMS differs from acute pain during exercise. It peaks 24-48 hours post-workout and fades within 72 hours. The pain results from microtears in muscle fibers, inflammation, and metabolic waste buildup. While uncomfortable, DOMS indicates muscle adaptation and growth.

Main Types of After-Gym Muscle Pain

Type	Timing	Cause
Acute Soreness	During/immediately after exercise	Lactic acid buildup
Delayed Onset (DOMS)	24-72 hours post-workout	Microtears in muscle fibers
Chronic Pain	Persistent beyond 72 hours	Overuse or injury

When to Seek Medical Attention

Severe or persistent pain may signal injury. If swelling, sharp pain, or limited mobility occur, see a healthcare provider. DOMS should fade within 72 hours; lasting pain requires evaluation.
