There is no definitive answer to this question as it depends on individual needs and preferences. However, a hyperextension bench may be worth it for some people, depending on the reasons they are considering purchasing one.
Some people might find that a hyperextension bench helps them achieve better results when working their abs or glutes. The bench can provide an extra range of motion for these exercises, which may lead to more muscle growth or definition. Additionally, the bench can help improve balance and stability, both of which are important for athletes and everyday exercisers alike.
On the other hand, some people might not need or want a hyperextension bench. Those who are already able to do full extensions with good form may not get many benefits from using the bench. Additionally, those who are new to working out or have any joint issues should consult with a doctor before using this type of equipment.
