Working Out: How Long to Wait. If you have a workout routine that is scheduled for a few times a week, try to wait at least 48 hours after getting your tattoo before you work out. However, if you are in training or cannot function without a daily workout, you can cut the time to 24 hours.
How long should you wait before you touch up a tattoo? A tattoo is not fully healed until a new outer layer of skin has grown in. This usually takes about three months. Until the tattoo is fully healed, the area is vulnerable to the bacteria found in swimming pools and lakes. Waiting a minimum of two weeks to go swimming reduces the risk of irritation and infection, but if the tattoo has not completely healed, it is necessary to clean the area thoroughly after swimming.
