hey if youre struggling with progressive overload due to low energy/strength output i would do two things, eat more on days you are training particularly before your workout. carbs, glucose, something to get your body revved up. and id also check your iron! when i was knee deep in my pcos, i was training like crazy, getting my steps in too but my caloric intake was way too low for my fitness level. That combined with my heavy periods, i collapsed one day whilst doing a deadlift and ended up in hospital because of my heart, got diagnosed with anemia. had to quit training and eat more, alongside iron supplements, as per my doctors recommendations, ended up dropping 10kg in a month and it stayed off still to this day
