When Matthew complains that his pants are too tight, he realizes he's gained a little weight and Christine offers to train him. Turns out her "protein shakes" were high calorie milkshakes and they've both gained weight. Barb volunteers to train them at her gym, a smelly, sweaty boxing gym. Christine works her ass off and Matthew does next to nothing, yet he loses tons of weight and Christine almost none.
Also, Richard makes a point of talking to Ritchie in front of the meanie moms, asking Ritchie if he's okay with Richard's impending marriage. When Ritchie says no, Richard is flummoxed as to how to handle the situation.
