Weight training apparatus with adjustable exercise angle

A weight training apparatus comprising:

• a main frame;
• first and second exercise bars hinge-coupled to one side of the main frame and configured for a user to push or pull using handles;
• and
• an exercise bar rotating unit configured to rotate the first and second exercise bars in mutually opposite directions with respect to their longitudinal central axes,
• wherein the exercise bar rotating unit includes:
• a first bracket fixedly coupled to one end of the first exercise bar so as to rotate with the first exercise bar;
• a second bracket having a securing pin, fixedly coupled to one end of the second exercise bar so as to rotate with the second exercise bar;
• a holder including a plurality of angle adjustment holes, formed to secure the securing pin inserted into one of the angle adjustment holes;
• and
• a connecting bar connecting the first bracket and the second bracket, and configured to transmit a rotational force of the second bracket to the first bracket so that the first and second exercise bars rotate with respect to the central axes according to the rotation of the second bracket.
