a main frame, having a first end and a second end remote from each other;
two first wheels, each in a rotatable state, disposed at either side of the first end;
a second wheel, in a rotatable state, disposed at the second end, allowing the main frame to be displaced by utilizing the rolling of each of the first wheels and the second wheel;
a damping structure, disposed on the main frame and connected to the second wheel to provide a damping effect to retard the rolling of the second wheel;
an operating handle, erected at the first end of the main frame;
an auxiliary push frame, erected at the second end of the main frame and including a stand portion and a handlebar portion coupled to the upper end of the stand portion;
an enhanced weight load holder, disposed on the handlebar portion and including a stop portion spaced from the handlebar portion to form a handgrip clearance space H; and
a weight member, placed on the enhanced weight load holder and limited in position by the stop portion, thereby varying the center of gravity of the load in the weight training sled.
