Can The Hollow Body Rock Exercise Lead To Back Pain?

The Hollow Body Rock is a core-strengthening exercise that builds stability, endurance, and control by engaging your entire midsection through a dynamic rocking motion.

Disclosure: The information here is for learning and should not replace advice from a doctor or therapist. If you have back pain or other health issues, talk to a professional before trying new exercises. The Hollow Body Rock is a tough core workout that may not suit everyone, especially if your back is sensitive or injured. Doing it the right way is very important to prevent the risk of injury.

I have a great question from a Fix My Back Pain customer that I wanted to answer for him but then also do a video on it because I think it will end up benefiting you.

The question comes from Selven and what it has to do with the Hollow Body Rock Exercise.

His two specific questions are:

1. Is the Hollow Body Rock a sit-up or a crunch?
2. Does Hollow Body Rock cause back pain?

Now, maybe I will take a step back and briefly explain what a Hollow Body Rock Exercise is. However, it’s an exercise that I don’t often do as it puts a lot of strain on my back.

Benefits Of The Hollow Rock Exercise

• Builds a Strong Core: Hollow rocks help strengthen your belly muscles, making your core stronger and more stable. Moreover, John Carroll, a fitness enthusiast, tried Hollow Body Holds every day for a week. He said his core felt much stronger, especially his lower abs. He also mentioned that keeping good form was the most important part to avoid pain.
• Improves Posture: This exercise helps you stand and sit straighter by strengthening the muscles that support your back and spine. Moreover, Carroll also noticed that his posture improved after a week of practice. His back felt more supported during the day, which made standing and sitting more comfortable.
• Teaches Body Control: The rocking motion helps you learn how to control your body better; moreover, it is useful for everyday movements and workouts.
• Helps Prevent Injuries: The rocking motion helps you learn how to control your body better; moreover, it is useful for everyday movements and workouts.
• Boosts Fitness Progress: Hollow rocks are a stepping stone to harder moves, like handstands or advanced gym workouts.
• Supports Your Spine: By keeping your back flat on the floor during the exercise, you train your spine to stay stable and safe during movements.

How To Do The Hollow Body Rock Exercise?

I will demonstrate it to the best I know how to do the exercise.

1. Lie down with feet together and toes pointed away. And, arms are overhead.
2. I want to round out the lower back and have the full back rounded. I am going to lift the hands up a bit, and I am going to lift the feet, and I am utilizing my abdominals in order to rock my body back and forth.

That’s how you do the basic hollow body rock exercise.

Important tips:

• With proper form and core control, start with shorter durations or fewer repetitions, gradually increasing as your core strength improves. Otherwise, if done improperly, it can potentially strain your back.
• If the exercise is challenging, initially begin with your knees bent and progressively straighten your legs as you gain strength.

That’s how you do the basic hollow body rocks exercise.

Shane McLean, a certified personal trainer, explains that the hollow rock exercise is a simple but powerful way to strengthen your core.

He says it helps build strong abs and improves your ability to keep your spine stable during movement.

Shane says this exercise makes your body stronger and better balanced. Moreover, it helps you do other moves, like squats, deadlifts, and overhead presses, with better form.

The hollow rock makes your core stronger and steadier, which is super important.

Whether new to working out or already have experience, adding the hollow rock to your routine can help you build more balance and strength.

Now, answering Selven’s specific questions:

Is The Hollow Body Rock Exercise A Crunch Or A Sit Up?

— Well, it’s neither one of them.

It is a gymnastics conditioning exercise that targets the lower abdominals. Gymnastics has given rise to this exercise, and it has become quite popular of late due to the rise of Cross Fit since gymnastics is a component of Cross Fit.

Does The Hollow Dody Rock Exercise Lead To Back pain?

–— And the quick and simple answer to that is YES.

Most people have poor technique when performing this exercise, and as a result, it increases the chance of injury. That is why I believe this is a difficult exercise for the average person.

Summarizing what my advice would be when it comes to the Hollow Body Rock exercise is, if you have had back pain or if you have back pain, it is an exercise that puts lots of load on the spine and increases the risk of back pain, back injury, and back flare up.

I would advise you not to do it if you have back pain or old back injury.

If you want to give it a try or master the exercise, just make sure you get good coaching and guidance on it.

There you go Selven, thank you very much for the two questions when it comes to the Hollow Body Rock exercise.

Interestingly, the Hollow Rock Exercise has been incorporated into strength training programs for individuals with cerebral palsy ^[1] (CP).

A recent study used this exercise as part of a program to improve trunk stability and core strength in young people with CP.

By strengthening the core, participants enhanced their posture, balance, and walking ability. However, it also emphasizes the importance of proper form, especially for those with pre-existing conditions.

Hollow Rock Variation Exercises

1. Bent-Knee Hollow Rock

• Lie on the floor with your feet close together and arms on your side, relaxing your upper body.
• Extend your arms above your shoulders and bend your knees at a 90-degree angle.
• Contract your core muscles. Press your lower back firmly into the ground.
• Gently rock forward by lifting your knees toward your chest and rounding your upper body.
• Maintain a small and controlled range of motion. Repeat the movement. Complete 10–15 repetitions.

2. Hollow Hold Position

• Lie flat on your back with your arms extended overhead and legs straight. Contract your abdominal muscles and press your lower back into the floor.
• Round out your lower back to lift your arms, head, shoulders, and legs off the ground, forming a “banana” shape with your body.
• Hold this position for 10–30 seconds.
• Slowly lower your back down to return to the starting position.

This rocking hollow body hold adds a gentle motion while still focusing on holding the position.

Jane McGuire tried incorporating Hollow Body Holds into her routine.

She experienced both challenges and rewards. She committed to doing them for three minutes every day for a week.

While maintaining good form proved tough initially, she noticed a stronger core and better workout control by week’s end. Her key takeaway? Start slow and prioritize techniques to protect your back.

Echoing Jane’s sentiments, Philip Stefanov, a personal trainer and strength coach, emphasizes the value of the hollow hold as a key exercise for building core strength and enhancing spinal stability.

He stresses the importance of gradual progression and proper form to maximize its benefits and prevent injury.

Stefanov warns against common mistakes like letting the lower back arch, holding your breath, or advancing too quickly, as these can reduce the exercise’s effectiveness or lead to injury.

He encourages steady improvement and consistency to strengthen deep core muscles and prepare the body for more advanced movements.

3. Single-Leg Hollow Rock

• Lie on your back with your legs straight and arms on your sides, relaxing your upper body.
• Bend one leg at a 90-degree angle and engage your core.
• Press your lower back firmly into the floor and lift your head, shoulders, and the opposite leg off the floor, holding the bent knee gently with both hands.

Begin a gentle rocking motion by slightly lifting and lowering your extended leg while rounding your upper body forward. Repeat the movement. Complete 10 repetitions on each side.

If you want a more challenging movement, lift your leg higher without holding your knee.

Jeff Cavaliere, a certified strength coach and former Head Physical Therapist for the New York Mets, recommends the hollow rock exercise as one of the best for building a strong and stable core.

Cavaliere explains that it works by keeping your abs under constant tension, helping to improve strength, endurance, and control.

He stresses the importance of doing the exercise with proper form and adjusting it to your fitness level to stay safe and get the best results.
