Final answer:
If I see someone struggling without a spotter during a bench press, I would offer assistance to ensure their safety.
Step-by-step explanation:
If I saw someone struggling to complete a difficult bench press without a spotter, I would intervene to ensure their safety. First, I would approach the person and ask if they would like assistance or a spotter. If they accept, I would stand behind them with my hands ready to assist them in case they need help or can't complete the lift. It is important to be cautious and not attempt to lift the weight for them, but rather provide just enough support to keep them safe while they finish the exercise.
