I agree, but I can't exactly go running in athletic shorts with my Shield in my pocket.
I dont know how you carry iwb but i run/workout with this set up no problem (centerline carry).
Even a small 380 in the pocket of athletic shorts will flop around to much for my liking. Or you can do a bellyband kind of holster and stick with your shield in that. There is plenty of athletic wear now with belt loops so i stick with iwb rigs even for workouts/running, etc.
