Program description

This online course is for your baby who shows signs of back arching, can’t get out of the skydiver position on their own or has a flat back of the head. All exercises are based on current professional standards and are based on physical therapy, i.e. muscle strength training to restore a healthy muscular balance. Therefore, you can safely use these exercises regardless of whether your baby has mild or pronounced symptoms.

Back arching is not a medical diagnosis, is not dangerous for your baby and is not a sign that something is seriously wrong in the long run. However, it is a functional diagnosis that can challenge motor development due to a muscular imbalance. This imbalance occurs because the extensor muscles in the back of your baby’s body are stronger than the flexor and rotator muscles in the front. For proper and natural motor development, this should ideally be the other way around. In fact, our entire stabilizing muscle system depends on strong rotational muscles. Back arching therefore slows down your baby’s ability to discover rotational movement patterns, which are fundamental to rolling, pivoting, belly crawling and crawling on all four.

All exercises are thoroughly described, ordered by priority, and are illustrated with pictures and videos so you are never in doubt about how to perform them. When I update any content based on new research results, you will have immediate access to it, when you log back in, so you will always have access to the latest knowledge.

If you have any further questions about the program or are unsure about anything, please send me a message (maybe attach a short video of your child) via my Instagram @develobaby or by email at

Note: if your baby has no back arching symptoms, I recommend that you consider the alternative program Tummy Time.
Note: if your baby is able to roll from back to tummy and can pivot (change direction in tummy position), I recommend that you consider the alternative program Belly Crawling.

The most common signs of back arching?

  • The baby overextends the back and neck, e.g. when they are held close in a hug or during breastfeeding.
  • The baby rolls (tips over) from tummy to back early and involuntarily.
  • Flat head in the middle of the skull (brachycephaly). Often, back arching babies prefer to sleep with their head in a central position.
  • The baby has difficulty with tummy time and quickly becomes tired and restless when lying on their tummy.

  • The baby does “The Skydiver” in the prone position. They lift their arms up and extend them backwards.
  • The baby often lifts the bottom up in the supine position and may push themselves back.
  • When sitting, the baby will extend the arms back opening the chest and bringing the shoulder blades together.
  • The baby likes to stand up from an early age (<6 months).
  • The baby rolls from back to tummy with an overextended neck.

  • The baby does straight sit-ups from the supine position.
  • Later in development, back arching babies will often use what’s called a “centered belly crawl” using both arms and legs at the same time (without crossing movements). Here I would recommend my Belly Crawling exercise program, which also has a strong focus on rotational activation.
  • Many babies who belly crawl without cross movements will later sit themselves up and bum scoot forward in a centered movement.

Frequently asked questions to Back Arching and Flat Head

Back arching occurs because there is more firing (activity) in the muscles that stretch the joints of the body and in the muscles that work in the center of the body, i.e. straight movements, than in the muscles that create rotational movements. This may be a bit complicated to understand if you don’t have an in-depth knowledge of the human body, but it means that the child is too active in the extensor muscles and therefore has more difficulty with movements that require rotation and lateral coordination (tummy time, rolling, pivoting, crawling, and scooting).

Back arching is not dangerous! It’s not a medical diagnosis, and it doesn’t mean there’s anything wrong with your baby. Rather, back arching is a functional diagnosis that can challenge and delay your baby’s motor development. So it makes sense to work with back arching to give your baby the best possible foundation for development.

Some children will eventually outgrow their back arching if they are given enough tummy time and are motivated to do lots of rolling and other cross-coordination. The back arching exercises in this program just make it more likely that the lack of rotation won’t interfere with crawling and motor development in general. But you should never feel like a bad parent if you choose not to do this. Every priority needs to fit the bigger picture of your whole family, and motor development isn’t always at the top of the priority list.

No! The exercises are normal strengthening exercises in the anatomically normal muscle pattern. This means that even children who do not arche their backs at all can do these exercises and achieve a stronger body. The worst thing that will happen is that you will be supporting your baby’s motor development.

Because I know that many families find it overwhelming to do exercises in their daily lives, I have organized the exercises in order of priority. The most important exercises are at the top, so if you’re short on time, those are the ones you can focus on.
By doing specific exercises as part of all the little things you do with your baby throughout the day, you can usually break back dominance fairly quickly and get your baby back on the motor track.

There is a whole section in the program with additional exercises and measures if your child has a flat back of the head due to back arching.

The exercises are general, targeted strength training designed to free your baby from the involuntary back arching. The exercises are based on best medical practices and are not an alternative treatment. However, there are some children who need a more individualized exercise program. This is usually the case with children who have a strong involuntary tendency to arche their backs or special circumstances surrounding the baby. However, strength training for back arching will work for the vast majority.

Then simply log in again with your email address as your username and the password you chose during the checkout process.

My exercise programs are accessible online here on As the programs contain video clips that couldn’t be played in PDF or other types of print, there is no downloadable or hard copy version. That said, using a PC/Mac you can in fact print the exercise programs you have purchased by pressing Ctrl+P on Windows and Command+P on MacOS when you are on the exercise program page. However, the programs are not specifically set up for this purpose, so it’s much nicer and more user-friendly to view it directly on your mobile, tablet or computer.

You have perpetual access. However, I am obliged to adhere to certain privacy data regulations (such as GDPR), which state that I cannot store customer data longer than necessary. Therefore, the system limits your access to one year at a time. When a year is about to expire, the system will automatically send you an email so you can easily extend your access if you want to keep it.

No, this would be against the terms & conditions. You purchase access for yourself and the people living in your household. If you, however, buy an exercise program as a grandparent, you can of course share the access with the person you bought it for. In contrast, if you are a manager in an institution and want to procure access to one or more exercise programs for your employees, please write to me so we can work out an agreement on multiple licenses. For contact details and more, please see my Terms and Conditions.

Current legislation states that the usual 14-day right of withdrawal does not apply to digital products. The reason for this is that it is virtually impossible to argue that you haven’t used digital products once you’ve logged in. Therefore, I do not generally offer refunds. Please read more about my return policy under Terms and Conditions.

Yes, I’ve gone to great lengths to explain each exercise in layman’s terms so that everyone can follow. There are also pictures and videos to accompany the exercises, where I perform the exercises on a real baby.

No, certainly not. In my exercise programs, I have put the exercises in prioritized order. There are a lot of exercises in each program, so in principle you can spend your whole day doing exercises if you find it enjoyable, but you can also choose to do the top three or top five, and therefore the most important ones. This makes the exercise programs suitable for everyone, no matter how much time and energy you have to spare.

The exercises are basically just strength training, just like when you go to the gym. They are designed to strengthen your child muscles wrt the exercise programs’ purpose, e.g. addressing back arching. Therefore, exercises will always make your child stronger. Whether your child achieves each milestone with good quality using the exercises depends, of course, on the starting conditions and whether there are any special conditions that would require a individually tailored approach. But no matter what, helping your child build a stronger body will never be in vain. For the vast majority, standardized exercises, as presented in my exercise programs, will help the child move on to the next milestone well and strongly.
