I've always had this problem, haven't tried very hard to solve it, just assumed it was permanent.
I play basketball 2-3x a week in the same workout shirts. Eventually washing did not help get the stench out.
Soaking in oxi clean for 10-15 min then going through a regular wash has been the only thing that can get it back to fresh.
