Explosives Progression#1890

I’ve been doing the hybrid routine for a while and it’s worked very well for me. But one thing I’m not sure about as a begginer is explosives progression, its the only thing i don’t have nailed down, and i noticed that it is atcually mentioend in the routine but stuck in comming soon. I’d love to get some feedback about progressing in explosives at home, i was especially confused how to proress when there is upper and lower body and all these vairations. Thank you for your time.
