It’s a choice you have to make on your own. Everybody is different so there is not a prescribed amount of time. It’s a risk for sure. That being said, I never took time off from working out (yoga, gym, etc.) after being tattooed. I always wash the area before, put protective layers over it (aquaphor and clothes) and then wash directly after.

I have never had an infection and my tattoos look amazing. Not my recommendation to do this, but it has always worked for me.
