DJ Pro AI is really underrated. Frequently updated, extremely fast and good hardware compatibility. While it may not be as "robust" as traktor, everything else feels like going back in time.
Get good shoes, this can make a huge difference. Apart from that it's just staying consistent and walking as much as possible and you'll be able to do over 20km pretty soon (depending on your current fitness ofc)
