^ The proof is in the pudding, my dear Foodbandit. This "pudding" is other episodes. Big Mac is implied to be "the strongest stallion in ponyville." And if you want specific proof, I would suggest watching Hearts and Hooves Day. In the episode, Big Mac not only drags a cart and oxes, but also an ENTIRE HOUSE! (with residents inside!) with no apparent effort. Plus, Big Mac is never givin help to lift it (the cake). All help givin to him is to keep it from toppling over. Physically, the cake's apparent instability can only be caused by two things: Big Macintosh has a very round/uneven back, or the cake's center of gravity was very high (as in elevation) due to its height (as in its dimension on its z axis).

Also, we never see BM picking the cake up. The episode opens with Pinkie talking to the Cakes, and then we see him straining, with the cake on his back. Given the information above, we can safely say that the strain was not due to weight, and possibly also say that it was instead due to instability.
