I liked dzogchen teacher who used to say "use what works for you".
Anyway, Tsoknyi Rinpoche includes qigong somewhere, I believe I have seen it in their online course: https://fullybeing.org/courses/warmups/
And I have heard one buddhist practitioner talking about going very early out in the field to practice, only meeting I believe Tsikey Chokling Rinpoche practicing some kind of qigong.
And I have listened to Lama Lena's teaching few days ago, while to one practitioner she recommended tummo IIRC, to another taichi, based on what she thought was best for each individual.
