Inconsistent treatment of exercise during pregnancy

Sims can not jog, do sit ups, push ups, stretch or climb the rock walls in Mt. Komorebi (Snowy Escape) while eating for two, yet can use the treadmill (which is essentially the same as jogging), the workout machine, the punching bag, the rock climbing wall from Fitness Stuff, and do TV workouts (with the Power Sculpting workout including both push ups and sit ups) up to second trimester. They can spar with the training bots (Strangerville), use the archery range and spin cycles (Adventure Awaits) but not practice swordsmanship on training dummies (Royalty and Legacy).

There is absolutely no rational reason I can see to prohibit pregnant sims from stretching, even in the third trimester. If sims can use the treadmill, they should be able to jog. Conversely, if they can't jog, they shouldn't be able to use the treadmill. Similarly, if they can do a power sculpting workout, they should be able to do push ups and sit ups, but if they can't do push ups or sit ups, they shouldn't be able to do the power sculpting workouts. Same-same natural rock walls and rock wall climbing machines.
