My workouts are pretty basic. Basketball when I can and if I can't play that day I'll lift after work (provided that I didn't lift the day before) following a stronglifts A/B routine (squat, Dl, BB Rows, Bench, Press). Clearly I'm not an endurance athlete but I ran a 5k today because a coworker was organizing it and in the 5 hours since I have had 4 bowel movements and I can feel another one building up. Is the run really causing this or is it a function of a bad diet? It's a bit concerning to me...
