Performing the: A Step-by-Step Tutorial 45 degrees Back Extension
Cross your arms over your chest or place your hands behind your head, maintaining a straight back and neutral neck.
Slowly lower your upper body down towards the ground until you are at about a 90-degree angle with your legs, ensuring you are bending at the hips and not the waist.
Pause for a moment at the bottom of the movement, then slowly lift your body back up by extending your hips until you return to the starting position.
Repeat this movement for the desired number of repetitions, ensuring you maintain a controlled motion throughout the exercise, and avoid hyperextending your back at the top of the movement.
