excercises: mostly heavy squats, maybe heavy deadlifts, 

if it's heavy weights then it's the core of the abdomen squeezing, 

which would have strong effect on squeezing rectum 

if it's light weights then it's probably just belly muscles squeezing, 

which would have little effect on squeezing rectum
