Ostrogradsky’s approach to mechanics is rather interesting and valuable. Particularly, the formulation of generalized canonical dynamical systems which describe many processes in the real physical world, can be done better using this approach. Here the author shows that there is a possibility of constructing canonical model of free spinning particle motion in the special theory of relativity. After a brief overview of the classical spinning particle theory, the Hamiltonian dynamics of a free relativistic top is developed, which is then followed up by calculations. It is demonstrated that the Legendre transformation is equivalent to solving the Poincaré-invariant inverse problem of calculus of variations, and the corresponding Euler-Poisson expression is written out in differential form.
