Choose big compounds
Compounds train several muscles at once, so a squat, bench or overhead press, and a row hit most of your body in a handful of sets. Isolation work is what you drop first when time is tight.
Pick 3 to 4 compound lifts, superset opposing muscles, keep rest to 60 to 90 seconds, and skip the fluff.
Thirty minutes is enough if you cut the junk. Do 3 to 4 compound movements that cover the whole body, like a squat, a press, and a row, and superset non-competing pairs to save time. Keep rest to 60 to 90 seconds and go near failure so fewer sets still count. Full body 3 times a week in short sessions beats a skipped 90 minute plan.

Pair movements that do not compete, like a set of rows while your legs recover from squats, or push with pull. This roughly doubles your work density without rushing individual sets.
With less time you cannot afford lazy sets, so take each to within 1 to 2 reps of failure. Three hard sets near failure beat five half efforts you would have padded a longer session with.
