Zeina

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?
