Gym alternatives?

[Zeinaa]

Hi everyone,
I wanted to know if anyone knows what kinda exercises I can do to substitute stuff like lat pull downs, and rear delt pulls. I have a resistance band (the one the looks like TRX) but It's not as intense as I'd like and I finish my reps way too easily. I also have a couple of weights and DBs, so if anyone maybe knows a way I can transform my Rb into a diy cable machine that'd be good. Otherwise, what are some good ways to substitute cable machine exercises?

chinups (BW), pullups (BW), inverted rows (BW), bent over rows (DB), Pullovers (DB,BB,Bands), Lying rear delt row (DB) and Face pull (Bands)

to name just a few

I don't know what you mean by a Rb
