Prior to starting an endurance fitness program, a sedentary middle-aged person should do which of the following?

While consulting a personal trainer can provide valuable guidance on exercise techniques and program design, it should not be the first step for a sedentary individual. Without first ensuring their health status through a medical checkup, they may risk exacerbating undiagnosed conditions during physical activity.

Inquiring about appropriate exercise types is helpful, but it assumes the individual is already fit enough to engage in physical activity. Without a medical checkup to assess their readiness and safety for exercise, this step may lead to inappropriate recommendations that do not consider potential health risks.

Jumping into an equipment-based exercise program without prior health assessment can be risky for someone who has been sedentary. This approach could lead to injuries or health complications, especially if the person has underlying conditions that need to be evaluated by a healthcare professional first.
