The research aimed to develop a proposed training program using the reverse planning model and find out its impact on the components of muscular strength (maximum strength - muscular ability - force endurance) and some physiological variables (lactic acid - hydrogen dehydrogenizing enzyme) and the level of performance of some force movements (V-angle anchor and stability 2 s - climb by force to stand on the hands and stability 2 s) on the ground exercise device for junior gymnastics under (11) years, and the researcher used the experimental approach on a sample of (10) junior gymnastics under (11) years, Among the research tools: physical tests - physiological measurements - evaluation of the level of performance of some force movements on the ground exercise device - training program using the reverse planning model. Among the most important results: 1- The use of the reverse planning model has a positive impact statistically at the level of (0.05) on the components of muscle strength (maximum strength - muscular ability - strength endurance) for junior gymnastics under (11) years. 2- The use of the reverse planning model has a positive effect statistically at the level of (0.05) on the physiological variables (lactic acid - dehydrogenizing enzyme) for gymnastics juniors under (11) years. 3- The use of the reverse planning model has a statistically significant positive effect at the level of (0.05) on the level of performance of force movements (V-angle and stability 2 s - strength climbing to stand on the hands and stability 2 s) on the ground exercise device for junior gymnastics under (11) years
