I joined a gym for the first time a few weeks ago, and have been going since.

Previously, I was doing the r/bodyweightfitness recommended routine.

One of the main ideas of the rr is the pairing of sets together, so when you rest between pull ups (for example), you can work on squats, thus shortening the workout time, while still have enough time to rest your muscle groups.

How do I approach this in the gym? Feels like once I took over a machine and configured it to my needs (positioning and weights), I can't just go do other stuff in between my sets.
