The 45 degree twisting hyperextension is a bodyweight back exercise that primarily targets the erector spinae along your spine and the hamstrings, while the added rotation brings the obliques into play. Performed on a 45-degree hyperextension bench, the gluteus maximus assists at the hip, making it a strong choice for building a more resilient, well-rounded posterior chain and core.
How to do the 45 degree twisting hyperextension
- 1Set the foot and hip pad of a 45-degree hyperextension bench to your height and position your hips just above the top of the pad.
- 2Anchor your feet under the foot rollers and let your torso hang down so your body forms a straight line from heels to head.
- 3Cross your arms over your chest or place your hands lightly behind your head, and brace your core.
- 4Hinge at the hips and lower your torso toward the floor under control until you feel a stretch in your hamstrings and lower back.
- 5Drive your torso back up by contracting your erector spinae, glutes and hamstrings until your body is straight, without overextending.
- 6As you reach the top, rotate your torso to one side to engage the obliques, keeping the movement controlled.
- 7Return to center, lower under control, and repeat the rotation to the opposite side on the next rep.
- 8Alternate sides for your target reps, then carefully step off the bench.
Form tips
- Initiate each rep from the hips rather than yanking with your upper back, so the erector spinae and hamstrings do the work.
- Keep the twist slow and deliberate at the top — rotate from the trunk, not by throwing your shoulders.
- Maintain a long, neutral spine through the hinge instead of rounding your lower back.
- Alternate sides evenly so both obliques get equal volume and your core stays balanced.
- Add a light weight plate held to your chest only once you can complete clean bodyweight reps with full control.
Common mistakes
- Hyperextending the spine at the top instead of stopping at a straight line, which compresses the lower back.
- Using momentum to swing up and twist, which removes tension from the erector spinae and obliques and reduces the training effect.
- Rounding the lower back during the hinge, which shifts load onto the spine and raises injury risk.
- Pulling on the head or neck when the hands are behind it, which strains the cervical spine.
- Twisting too far or too fast, which torques the lumbar spine instead of working the obliques.
Frequently asked questions
What muscles does the 45 degree twisting hyperextension work?
It primarily works the erector spinae and hamstrings, with the obliques engaged by the twist and the gluteus maximus assisting at the hip.
How is it different from a regular 45 degree hyperextension?
The standard version is a straight hip hinge for the erector spinae, hamstrings and glutes. Adding the twist at the top recruits the obliques, training rotation along with extension.
Is the 45 degree twisting hyperextension good for beginners?
Yes. It uses only bodyweight and a 45-degree hyperextension bench, so beginners can master the hinge and a controlled twist before adding any load.
How many sets and reps should I do?
For most people, 3 sets of 10–15 controlled reps, alternating sides, works well. Prioritize a smooth hinge and a controlled twist over high rep counts.
Where should I feel this exercise?
You should feel it through the lower back along the erector spinae and the hamstrings, with the obliques working at the sides of your waist during the twist.
