Strength training for women

Krafttraining bei Frauen
The fear of looking like a man in the long run through strength training is absolutely unfounded.

Die Mythen, die über das Krafttraining bei Frauen existieren, führen dazu, dass die Vorteile und die Effektivität des Trainings sowie die Entwicklung der sportlichen Leistungsfähigkeit deutlich eingeschränkt werden. Jedoch ist die Angst, durch Krafttraining langfristig so auszusehen, wie ein Mann ist absolut unbegründet. Denn ohne Einnahme von anabolen Mitteln ist das Risiko sehr gering. Obwohl physiologische Unterschiede zwischen Frauen und Männern bestehen, sind die meisten Frauen in der Lage, mit deutlich mehr Volumen und höheren Intensitäten zu trainieren als bislang angenommen wurde. 1


In the last 20 years we have gained more and more knowledge that women can be trained with the same programs as men. Due to various physiological differences, we have to consider certain factors when formulating the programs. Strength training is used in more and more sports as part of athletic training. Therefore it is important to check the physiological basics and to point out certain misunderstandings. 2, 3

Not only do women have fewer muscle fibers than men, the cross-section of the fibers is also thinner. This is another reason why women cannot look like men. In addition, the feathering angle of the muscles, i.e. the angle of tension of the individual muscle fibers relative to the direction of tension, is smaller. This is because the development of strength seems to be lower for women overall than for men. 4 Furthermore, this also influences the absolute force. The average total body strength of a woman is about 60% of the total body strength of a man. 5

An important factor for the different adaptation to strength training and for the development of maximum strength is the hormone testosterone. In women, the resting concentration is 10-20x lower. 6 It is precise during puberty that we can observe this difference most clearly. However, the concentration of normal growth hormones is higher in women than in men. This could indicate a compensatory mechanism in the adaptation of muscles and connective tissue.


The fiber distribution of the musculature in men and women shows only slight differences. However, there are indications that women tend to have more type I muscle fibers, i.e. slowly twitching fibers. The density of blood vessels in the muscle is higher compared to men. This makes the blood circulation in the muscle and the supply of oxygen more efficient. Taking into account the better energetic utilization of glucose and fatty acids, it can be estimated that muscular endurance is higher and the regeneration time between two units is significantly shorter than in men. 7


If you want to improve your athletic performance, there is no way around strength training. Why is that? Maximum strength is crucial for the development of explosive strength, which is crucial to performance in many sports. The maximum power provides the basis on which we can build specific to the sport. So it is absolutely necessary not to make any compromises in the development of the maximum force.

Strength training has an effect on the whole organism. In addition to increased athletic performance, strength training also has a positive influence on bone modeling and thus reduces the risk of osteoporosis, it strengthens connective tissue and supports injury prophylaxis and reduces non-functional body fat. Because the development of fat-free body mass is extremely important for women. 8, 9

Often the training load of women is below the limit that would be necessary to achieve an adjustment of the bones, muscles, cartilage tissue, tendons or ligaments. If the intensity is too low, the training effect remains minimal. And as we can see from the physiology, women are able to train with high intensities and volumes. To activate all muscle fibers, correspondingly high resistances are necessary. There is no evidence that strength training for women is dangerous or leads to injuries more quickly. 1


The programming must be individually adapted to the needs and sports-specific requirements of both women and men. The focus should be on exercises with free weights in order to ensure an appropriate transfer to the sport. In most of today’s sports, the development of explosive strength is crucial and this is fundamentally influenced by an improvement in maximum strength.

Die Vorteile von Krafttraining bei Frauen betreffen den gesamten Organismus und können die Körperzusammensetzung positiv beeinflussen, ohne das Körpergewicht stark zu erhöhen. Deshalb sollten gerade Rumpfübungen wie Bankdrücken, Latziehen oder Kreuzheben in das Trainingsprogramm integriert werden, um die Kraftgrundlagen im Rumpf auszubauen. Sobald die Grundlagen gelegt sind, sollte der Fokus auf die Entwicklung der Schnellkraft gesetzt werden. Dafür eignen sich Übungen aus dem olympischen Gewichtheben wie Push Press, Hang Clean, Power Clean, Clean & Jerk oder Snatch.

The objective is decisive. What’s the goal? What do you want to achieve? Progress in training must be monitored and evaluated accordingly. Only in this way can physical development be optimized.
