Explain how it might be possible to have good muscular endurance in the arms but nit in the lower body?

Good muscular endurance in the arms but not in the lower body can result from specific training focuses. If an individual regularly engages in activities or exercises that target the upper body, such as Weightlifting or rowing, their arm muscles can develop endurance through repetition and adaptation. Conversely, if they neglect lower body training, those muscles may remain underdeveloped and lack endurance. Additionally, genetic factors and overall activity levels can influence endurance in different muscle groups.
