An exercise system includes a flexible attachment member sized for positioning between a shoe's tongue and laces that extends beneath a majority of the laces. The attachment member includes opposed first and second faces, the first face having hook and loop coupling elements of a first configuration, the second face having hook and loop coupling elements of a second configuration. The exercise system includes a plurality of weight members, each having a first face with hook and loop coupling elements of the first configuration and a second face with hook and loop coupling elements of the second configuration. The hook and loop coupling elements of the first and second configurations are complementary to one another to couple at least one weight members to the attachment member first or second face and couple at least one the weight members atop a respective weight member coupled to the attachment member.
