An exercise machine and associated method for assisting a person in performing a push-up. The exercise machine has a body support platform that extends from a point of rotation at a variable angle of inclination. A user lays prone on the body support platform to perform a push-up. When a person laying on the body support platform performs a push-up, the body support platform rotates around its point of rotation from a first angle of inclination to a second angle of inclination. A bias mechanism is used to bias the body support platform toward one angle of inclination. Depending upon the needs of the user, the bias mechanism can be configured to either apply an upward bias to the body support platform that would assist a person in performing a push-up, or apply a downward bias to the body support platform that would resist a person in performing a push-up.
