It is a manifestation of psychokinesis. It should not need to be explained as it is a possible use of the ability.

The use of psychokinesis to increase your physical strength also seems very unlikely to significantly, if at all, impact you. The only impact it may have is by giving you the thought that it is affecting you, therefore it will.
