Final answer:
David's SMART goal is to improve his mile run time. To achieve this, he should engage in interval training, long-distance running, and cross-training, which aid in enhancing cardiovascular endurance.
Step-by-step explanation:
To set a SMART goal for David to improve his mile run time, a clear, well-defined, and attainable objective must be identified. For example:
David's Goal: To decrease his mile run time by 30 seconds within the next 6 months through a consistent training program.
This goal is:
- Specific: It states exactly what David wants to achieve (decrease his mile run time).
- Measurable: The goal is quantifiable by aiming to reduce the time by 30 seconds.
- Attainable: With the right training and dedication, it is a reachable target.
- Realistic: The improvement is moderate and achievable with effort.
- Timely: Set to be achieved within the next 6 months.
Three exercises that can help David develop his cardiovascular endurance are:
- Interval Training: Alternating between sprinting and jogging to enhance both speed and endurance.
- Long-Distance Running: Consistently running longer distances at a moderate pace to build stamina and endurance.
- Cross-Training: Incorporating cycling or swimming to improve overall cardiovascular health without over-stressing running muscles.
By engaging in these exercises, David can work towards improving his cardiovascular endurance and achieving his mile run time goal.
