Final answer:
If someone is struggling with a difficult bench press without a spotter, it is important to step in and offer assistance to ensure their safety. This can include providing spotting and suggesting alternative exercises or a lower weight level.
Step-by-step explanation:
In this situation, it is important to ensure the safety of the person struggling with the bench press. Without a spotter, they could potentially injure themselves. Therefore, I would approach the person and offer to spot them, providing assistance and guidance to complete the exercise safely. This would involve standing behind them, ready to assist if they struggle or fail to lift the weight.
Additionally, I would also suggest that they lower the weight to a more manageable level or use alternative exercises that target the same muscle groups. It's crucial to prioritize safety and prevent any potential injuries while weight training.
