well, she didn’t say it here, so no I was not aware. My advice is general.
How much a woman can do in her third trimester should be handled case by case, as no two pregnancies are exactly the same, and I also don’t know her level of fitness currently, and no internet stranger is in a position to give this sort of advice without actually working with her in person and consulting her nurse/midwife/doctor/whoever she is working with in her pregnancy. So therefore, the rest of my advice should be taken generally as well, and may not be appropriate for this individual:
In general, ‘specialized training’ will make absolutely no sense for a woman in her third trimester, UNLESS it is intended as an aid to a healthy pregnancy. So for instance, if a woman has been told she is developing some sort of problems with her lower back, and has been advised her to do work to strengthen it, then there may be a reason for specialization. If she just wants better glutes for general fitness purposes… that can wait 3 months.
I have seen women in their third trimester safely perform deadlifts, but caution should be exercised, and relatively light weights should be used. Dumbbells or a trap bar may be a good idea as well, both to make the movement easier, and because of the altered leverages created in pregnancy.
I would avoid front carries, and heavy carries in general, to avoid pregnancy complications.
Light kettlebell swings are probably fine, but no maximum effort throws/swings.
Honestly, @ChickenLittle , I’m baffled that the OP has neglected to mention the pregnancy. That’s pretty goddamn insane.
