rest 90s than repeat the whole thing.
This is how I do them right? No rest bwteen the sets, just 90 seounds?
Does it matter if i do them every other day or 2 days on 1 day off etc?
If you remove all of the “rest 90s” except for the last one that would be 1 set of 1 complex.
I can’t really tell your understanding from the way you have worded the question but you rest between sets and not between exercises.
You can try heavy weights if you want but you might want to keep the light ones close by
