Why Muscular Pain After Exercise?

When muscles are required to work harder than they're used to or in a different way, it's believed to cause microscopic damage to the muscle fibres, resulting in muscle soreness or stiffness. DOMS is often mistakenly believed to be caused by a build up of lactic acid, but lactic acid is not involved in this process.

Is it normal to like muscle pain after workout?

Exercise physiologists refer to the gradually increasing discomfort that occurs between 24 and 48 hours after activity as delayed onset muscle soreness (DOMS), and it is perfectly normal.

Is it bad to workout if your muscles hurt?

You can work out if you're sore. Don't exercise the same muscle groups that are hurting. Do legs one day and exercise your upper body the next. By doing so, you'll still be able to get exercise and allow your lower body to recover and rebuild.
