Muscles usually take 24 to 48 hours to heal completely and grow in size. This is the reason why bodybuilders subject a body part to a good workout and let it recover for 2 days so that it would heal itself and grow in the process. In case your muscles are fatigued or injured due to excessive physical strain, they might require atleast a week or even more depending on the amount of damage caused to the muscles.
