started gym last month and i noticed that my knock knees make it hard to do some single leg movements, lunges and bulgarians are like torture for me and my knees naturally rotate inwards( like on the pic) especially my right leg. on top of that i know my hips are not aligned (my doctor told me few years ago) but i don't know if it has any impact on my knee situation. is this fixable or is it just my natural bone structure ? do i push through when doing single leg exercises ? if i try to do a lunge and intentionally rotate my knee outwards and also put my weight on the outside of my foot instead of the entirety of my foot, the movement looks more normal but very unnatural and adds difficulty to exercises that are already hard like bulgarians. i'm not sure if i'm supposed to keep doing these exercises or drop them entirely
