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.
Immediate Aftercare. Exercise should be fine 24 hours after getting a tattoo if there is no discomfort, but make sure you follow appropriate aftercare instructions so it properly heals. Keep a bandage on the area for 24 hours. Clean your tattoo with antibacterial soap and pat it dry with a towel. You should use an antibiotic ointment on the tattoo in addition to an unscented lotion for moisture. Do not take a bath, sit in a hot tub or swim for two weeks after getting a tattoo.
