Fitness is generally understood as enhancing the health and function of the body through exercise. It involves the exercise of various muscle groups, improves cardiopulmonary function, promotes metabolism and improves the overall physical quality.
Practical ability mainly refers to the coordination and flexibility of hand muscles, joints and nervous system when individuals actually operate or complete a task. This ability is particularly important in our daily life, which directly affects the effect of completing various fine tasks.
Judging from these two definitions, although fitness mainly focuses on the improvement of overall physical quality, it does involve muscle exercise and coordination improvement. Especially when the fitness training contains some instruments or movements that need fine operation, such as dumbbell training and instrument training, these activities can really strengthen the muscle strength and coordination of the hands, thus improving the hands-on ability.
Fitness also helps to improve personal attention, concentration and endurance, and these psychological qualities also have a positive effect on improving hands-on ability.
We also need to realize that the level of practical ability depends not only on muscle strength and coordination, but also on personal cognition, experience, skills and many other factors. Therefore, although fitness can improve practical ability to a certain extent, it needs to be combined with other methods and ways to really improve this ability.
To sum up, fitness can indeed improve hands-on ability to a certain extent, but the specific degree of improvement depends on the way and content of fitness and other personal related factors.
