Final answer:
The fitness program may be impeded by inadequate training time for a marathon, possible demotivation due to a focus on problems, lack of incremental and measurable goals, and the risk of injury from rapid increases in training.
Step-by-step explanation:
The fitness program of a young man aiming to compete in a marathon in two weeks could be hindered by a few factors. Firstly, considering the limited time frame, inadequate training could be a significant barrier to achieving his goal. A two-week period is a relatively short amount of time for someone to prepare for the demands of a marathon, which typically requires months of dedicated training to build up the necessary endurance and strength.
Secondly, the mention of his monitoring of potential problems might suggest a focus on what is going wrong rather than building on what is going well, which could affect his motivation and confidence. It's critical to balance problem-solving with positive reinforcement.
Incremental goal setting is also crucial in a fitness program. He should ensure that he is setting realistic weekly goals leading up to the event and tracking progress against these goals. Without measurable and motivational milestones, it may be challenging to stay committed and gauge his level of preparation accurately. Lastly, there is a risk of injury by rapidly increasing training volume or intensity, which would immediately derail his plans.
