Happy new year!  The trainer comment was more about doing them slowly and not fast, although most of them were doing various setups, I wasn't paying them though just conversations. Only doing 3 things would become very boring for me, very quickly. When I've focused on a small number of exercises repeated, I hit plateaus easier... both physically and probably psychologically, plus I feel like joint pain was worse doing the same things. It keeps things engaging for me to switch it up and confuse muscle groups, plus it adds more cardio/aerobics mixed in, both of which I've wanted/needed to incorporate.

Pull-ups and squats I've always enjoyed, pullups always made sense to me because the muscles used felt like they translated more to my everyday living and made things easier, although I haven't done pull-ups recently, I don't have a bar anymore to do them on, I guess I could just do them on a tree or something but atm it's cold outside lol, squats yes, and I've mixed in some yoga stuff, although it would be the western type    not very exciting by itself but once you get your heart rate up, some poses become more  challenging to hold, so I've done some of that but not a lot. Rings sound like a great idea but I definitely don't have those at home and probably not ready for them!
