Higher gravity today

Did someone turn up the gravity today? Doing my Wednesday workout, completed the 2 each chinup/dip sets and sliding hamstring curls, these went ok but the row/pushup sets were more difficult than they were last Monday. I feel heavier. Wasn’t able to match the same clean rep numbers but still achieved my goals for the day. Ab-wheel rollouts went ok, but still not as easy as Monday. Now that I’ve completed the session I feel more “fatigue” than “post-workout”. Some days are like that though.
