No. Usually, most applicants for life insurance may be required to take a paramed exam paid for by the insurance company, if they want to purchase life insurance.
However, after you have been approved for your coverage, and paid your first premium and taken the paramed exam, you will not be required to take a physical exam again.
Life insurance companies understand your health may change over time, and they take that into consideration when determining how much they will charge you for your life insurance coverage.
There are even plans available that offer life insurance with no physical examination required.
