  This paper is devoted to evaluating exact anisotropic spherical solutions for
static self-gravitating systems through extended geometric deformation
decoupling technique. For this purpose, we consider an isotropic Tolman IV
solution and extend it to anisotropic domain by transforming both temporal as
well as radial metric potentials. To examine the physical viability and
stability of interior anisotropic solutions, we plot energy bounds, TOV
equation, causality condition and adiabatic index for the stars Her X-I and PSR
J 1416-2230. It is found that both obtained models show realistic behavior as
they fulfill all physical constraints as well as stability criterion. We
conclude that the extended gravitational decoupling approach provides more
proficient results to discuss the interior configuration of stellar structures.
