The 45-degree hyperextension exercise is a strength training activity primarily targeting the lower back, glutes, and hamstrings, promoting overall core stability and back health. It is suitable for individuals at all fitness levels, from beginners to advanced, as it can be easily modified to match one's strength and ability. People would want to do this exercise to improve their posture, alleviate lower back pain, enhance athletic performance, and reduce the risk of back injuries.
Yes, beginners can do the 45 degree hyperextension exercise, but it's important to start with lighter weights or even just body weight, and focus on form and control to prevent injury. It's also recommended to have a trainer or experienced individual guide you through the process to ensure you're doing it correctly. Remember to listen to your body and stop if you feel any discomfort or pain.
