Do you lack the space for a home gym or are you an advanced lifter that would benefit from the specialized machines?
If you glimpse inside the gym of a professional athlete you’ll generally find a comprehensive set of dumbbells, some Olympic bars + plates and a bench and not much else!
Plenty of examples of elite bodybuilders training with them.
Power lifters, however, tend to focus on the compound movements and therefore probably need less equipment.
That’s an overly broad generalization. If you look up pictures of Arnold Schwarzenegger’s home gym, it’s mostly machines.
