Increase your performance and achieve your goals. Improving your finger strength and the entire upper body muscle group. With our hangboards, you can also perform multiple stretching exercises


The offer of holds, hangboards, campuses and some other products for training makes someone who for the first time is considering acquiring one of them have doubts about which product will be better.
At Mutant Fingers we do not intend to carry out a study before the avalanche of brands and models that are flooding the market, nor to theorize about what is best for each thing. What we are clear about is that if someone is thinking of buying a training/warming hangboard, they must think about three fundamental aspects: the material it is made with, the design and the intended use of it.

All our products are made of wood for the simple reason that resin is more aggressive to the skin. Wood also allows us to refine the edges and shapes of our hangboards, and to adapt them to good working angles and ergonomics. This manufacturing process also allows us to make very light “portable” hangboards, which can be carried in a backpack, in a suitcase or hanging from the shoulder. This can give you the key to acquiring the lighter models of the Mutant Fingers. You must also bear in mind a portable hangboard is also a warm-up element and not just for training. Do not set aside the purchase of a hangboard to training alone. Think that climbing, bouldering or other sports that have the arms as the main engine have evolved in their study of muscle behaviour at any level. Performance is present before and after an effort. You will enjoy more and will prevent injuries.


Improving your strength in climbing is something that has been researched since the beginning of the training studies and plans. As climbing is an acyclic type of sport, with brief movements of varying intensities, it is not linked to a series of standard exercises that may be present in other sports. The strength exerted in climbing movements will depend on the position, size, shape and type of holds. Another important factor is the different styles of climbing (overhangings, slabs, boulders, resistance, etc.) that the climber himself will need according to his level and objectives.
A good potential strength base is not always applicable in a functional way. Finding the best body position will allow optimization of the joint angle along with the orientation and speed of movement. All this together with the greatest possible energy economy.
A good potential strength base is not always applicable in a functional way.
It is clear that every climber must be aware of what they lack and what they will need to improve their strength. Having a Mutant Fingers board at home is the first step to start having direct contact with knowing how your body works and what you need to start training. Remember that every climber has their different level and their own needs. The types of grips and holds on our boards and the variable angles they offer will allow you to warm up and train at various intensities.


All studies show the effectiveness of a good warm-up before the beginning of an activity, whether it is before training or before a sport activity. Our body has to know what we are going to demand from it. An effective warm-up will avoid possible injuries and above all the feared sudden blocking of the arm muscles (cramps) . A cold body tends to protect itself, contracting the muscles and reducing the flexibility of the joints. The change could be significant with just a few warm-up exercises on our hangboards.

Mutant Fingers hangboards are divided into the so-called fixed hangboards — which are larger and intended to be kept at home, at your training or gym place– and the portable hangboards. These are lighter and smaller so that you can take them with you everywhere and warm up at any time and continue your training on a trip or outing away from your daily environment. The two types of hangboards will serve you equally for both strength improvement and warm-up. Fixed hangboards have a wider variety of grips and will allow you to work out a wider range of muscle groups.


Any sport, whatever your level is, continuously challenges your body and allows you to set new goals. The goals are personal and take place on the most diverse playing fields: sport climbing routes, ice-climbing, bouldering, gyms wood walls, iron bars in cities for citizens to workout , crossfit warm-ups…

The important thing is to seek an adequate performance of your body, to improve and evolve in our training and in the warm-up before any sport activity. If we want a faster and more precise evolution, we will have to think about preparing ourselves to improve and enhance strength and flexibility.

At Mutant Fingers we believe that we must seek a balance between the body and mind and above all, to enjoy ourselves. Having one of our hangboards at home, or as close as the occasion allows, can be the step to simply start changing your habits and start feeling the evolution in your goals

It is no secret that training today has served to exponentially boost climbing performance and raise the world level exponentially. Apps, RRSS info, Websites, specialized gadgets, etc, are being developed and are available and make it easy to access to a lot of information related to training. 

Therefore, at times this “overload” of information confuses us , doubts arise and this makes us take decisions that are not always right when choosing our appropriate method.


INDIVIDUALIZATION: The most important premise in training. Many times we let ourselves be guided by what has gone well for other climbers which make turn into an error. Once we have defined our objectives, we must assess which methods will fit better with our own circumstances (physiological, environmental, social…)
PROGRESSIVITY. Due to the increasingly widespread “less is more” , it seems that in our sport , the idea of “falling short” is not well accepted, causing a high rate of injuries in this sport by a simple mismanagement of the loads … Still much to learn.
SPECIFICITY. Do you really think that doing chin ups with 30kg helps you in your 6c project? Maybe there are many other factors to analyze. Focus your training on your objective and your lacks; do not waste your time to get stronger if you keep falling at the same movement…

“You are as strong as your weakest muscle” (W.Gullich), a classic that will never be out of date…

Professional coach

I have been climbing for over 23 years and training climbers for more than 12. I cannot conceive climbing without an adequate physical, technical, tactical and mental preparation. Each one must find their own, individualized, and for that the experience and preparation of those of us who dedicate ourselves to this have already helped many athletes along the way.

I love to combine my job as a High Level coach with helping people of all levels to find their way in improving their performance. Without a doubt the new technologies and the greater knowledge in the field of climbing training are helping a lot in the evolution of this sport. Not only scientific evidence, but empathy, experience and adaptability are my keys to achieve results with my team 😉

In climbing, food is a very important factor to take into account; before, during and after the practice.
A correct nutritional planning will help us have an adequate morphology and body composition to achieve the maximum sport performance, as well as have good health which will allow to extend sport life as much as possible.
The ideal diet for climbers should be high in carbohydrate diet, moderate in proteins and low in fats. This will change according to the time of the season, weight gain or loss.

We have to start at the base, firstly a balanced diet and then sports nutrition.


1. A good diet – with quality food.
2. Calories adapted to your needs.
3. Macronutrients distribution, i.e. adequate amounts of CH, proteins, fats – vitamins and minerals.
4. Frequency of these meals.
5. And lastly supplements, and only in the case they are necessary.


  • Food must be easy to transport and not need to be kept cold.
  • They must make it possible to recover the glycogen deposits between route attempts. (Bread, pasta, dates, bananas, cereals…)
  • Food to be consumed during exercise should be low in fiber, low in fat, lactose free, with small amounts of protein, balanced amounts of fructose (as they are associated with increased risk of gastrointestinal symptoms).
  • They should not produce gas, intestinal discomfort and should be rapidly absorbed.
  • Hydrate yourself correctly BEFORE/DURING AND AFTER. Drink 400-600ml of liquid 2-3 hours before exercise. Since this is a short term, high intensity sport and that it is impossible to hydrate yourself during it, take advantage of the breaks between attempts to drink constantly as thirst is not a good indicator of hydration.

A good diet will not make you a champion, but a bad diet can turn a champion into a mediocre sportsman.
