Kraulkraftverstärker

The videos with the movements under water are great; but also Jens himself with his explanations are to be recommended. The online course is great all around. I booked the online course after a crawl course from the VHS, actually out of desperation, because the VHS course was a flop. In the online course I understood for the first time how the leg stroke works (to name just one example).

Kraulkraftverstärker is not only very informative and helpful for improving swimming technique, but also enriches the training with a lot of variety.
I am thrilled and never go into the pool without a training plan again.

Although I would by no means describe myself as unathletic, the requirements in the training plans at the beginner level went far beyond what I could achieve. As a beginner, you are happy to be able to do 50m in a three-breath rhythm. Of course, it is possible to select individual exercises and adapt them to one's own ability. However, the feeling left behind when you fall relatively far short of the requirements of a training plan for beginners is a bit frustrating. After the crawl booster course, I attended a real crawl course for beginners. This was again very motivating, because I got positive feedback on the technique. So: I've already learned something! ;)

Hi Jens, I started teaching myself how to swim crawl in January 2022. Among other things with your online course. Your clear and structured explanations have given me a lot of pointers. Your videos I have watched all several times and re-swam it. Last week I had a coaching appointment with a professional swimming instructor to have my swimming style checked for mistakes. The swim coach gave me very positive feedback and didn't find any major flaws in my technique. Mainly I have to work on my leg stroke. This is a nice success for me, because it shows that I am on the right track with your videos, among other things. The investment in your tutorial has paid off for me!

Methodology of the individual topics well structured and explained; Helps to improve own movements

I still use the app too little. Maybe I can say more in the next few months.

I wonder about the request at the times of Corona, where swimming is not possible for weeks. Regardless, the course for me, as an absolute beginner, is probably not the right one, unfortunately have not found anything else when I was looking for it and the crawl booster seemed very convincing.

The videos are well made, but in many places I can not see exactly what needs to be done, for example, the underwater train is shown very inadequately. This is too little for me to be able to apply it.

Constructive criticism:
I got gerede (on 08.02) an email from you: "2 weeks ago you decided to take my online course,..." i booked the course on 10/31. - NO COMMENT.
The headings of the chapters name the error - they should name the correct thing e.g.:
1. pull through: water pressure - pushing instead of tearing
2. pressure phase: dog and duck
3. no pull, no ride: the right immersion point

I learned crawl quickly through the videos. TOTH, I would like to see in the videos or in a special video longer-term phases of how to swim properly

Super videos, perfect for re-swimming, great and varied training plans and above all absolutely comprehensible explained and implementable! Thank you!

The videos and explanations as well as the possibilities to correct recognized mistakes help me to get better. I am currently focusing on arm work and breathing and have already been able to significantly increase my performance and endurance. Even though there is still a lot of work ahead of me.
Thanks! Good course!

The explanation of each technique instructions are very good. Detailed videos and good training content that is explained in detail. Provided you are already familiar with the crawl style. Rather not suitable for absolute beginners.

The explanations in the videos are good and clear. Since I have not yet practiced much, I can not yet say more. But it definitely brings you further. In other videos, something is simply shown without going into details. Here you are shown exactly how to perform the individual steps. Hand position, arm control, leg kick, etc.

Great , descriptive videos, varied plans.

Hello, I was particularly satisfied with the technical exercises. I still incorporate them into my daily training routine. What I also found good was the activation of the online course immediately after registration. The registration fee could not have been received by you yet.
Where I am still unsure is the breathing part of the course. 2 or 3 breathing. Surely this is also individual. For triathletes the topic breathing and orientation in open water would be interresant.
I have already recommended 2x more.

Due to back problems, I have difficulties with the water position - legs hang too low, leg stroke too irregular, more than 50m crawl at a time difficult. With Pull Buoy it's now much better, I can concentrate on the arm training of the first lessons and can crawl much longer. Only the leg stroke training I still have to get myself together....

I will work through the courses again from the beginning consistently from the fall. In the competition preparation, the exercises did not fit exactly into my schedule and I broke off the program.

Am still in the middle of it, but (felt) already become faster. Finally someone who can explain all the tiny details that matter and demonstrate with good shots (also underwater). Compliments also to the swimmer, because probably intentionally "swimming wrong" is not so easy. With the overcorrection exercises you feel a bit stupid, but the water and body feeling is trained....hab me once again looking forward to swim training, which is already special (do triathlon).

shows very nicely the typical mistakes and how you can hopefully train them away
