When selecting a fitness program, several factors should be prioritized to ensure effectiveness and enjoyment. Personal goals, such as weight loss, muscle gain, or improved endurance, should align with the program's objectives. Additionally, consider one's current fitness level to avoid injury and foster progress. Time commitment, available resources, and preferences for training styles are also important to ensure adherence. Finally, social support, whether from trainers or exercise partners, can enhance motivation and accountability in sticking to the program.
