Jared has begun an exercise program where he runs 4-6 miles four times per week. Which of the following could be a downside to this program?

• A. It does not allow for progressive overload.
• B. He may struggle with muscle imbalances or weakness if he doesn’t do any supplemental resistance training.
• C. He will not burn enough calories without the addition of strength training.
• D. He needs to include other forms of aerobic activity, such as swimming & cycling.

Answer: (B)

Verified step by step guidance

1. Understand the concept of progressive overload: Progressive overload refers to gradually increasing the intensity, duration, or frequency of exercise to improve fitness levels. Determine if Jared's program includes this principle.
2. Evaluate the potential for muscle imbalances: Running primarily targets the lower body muscles. Without supplemental resistance training, Jared may neglect upper body strength and core stability, leading to imbalances or weaknesses.
3. Analyze calorie expenditure: While running burns calories, strength training can increase muscle mass, which boosts resting metabolic rate. Consider whether Jared's program balances both aerobic and anaerobic activities for optimal calorie burn.
4. Assess the variety of aerobic activities: Running is a repetitive motion that can lead to overuse injuries. Including other forms of aerobic exercise, like swimming or cycling, can reduce injury risk and improve overall fitness.
5. Conclude by identifying the most relevant downside: Based on the analysis, the most significant downside to Jared's program is the potential for muscle imbalances or weaknesses due to the lack of supplemental resistance training.
