Introduction:

Strength training and fitness activities that pursue aesthetics or rehabilitation demand the implementation of novel training methods based on the practical application of science and technology. The study of the population attending gyms in the municipality of Holguin permitted the identification of weaknesses in terms of methodological preparedness, reflecting the need for further development and readiness for managing and guiding this activity.

Aim:

To design a methodological strategy supported by a theoretical conception that contributes to further preparedness and training of instructors at strength training gyms.

Materials and methods:

Theoretical and empirical methods and techniques, such as surveys, interviews, observation, and the review of guidelines to get information about the main topic of this study. The feasibility of this proposal was checked through expert judgment and user opinion.

Results:

The scientific assessment of the contribution demonstrated its pertinence and feasibility through favorable impacts measured by user opinion and the Likert scale in relation to the theoretical and methodological preparedness of the instructor.

Conclusions:

The qualitative and quantitative changes of the main topic of research showed the practical functionality of the methodological strategy suggested through a pre-experiment.
