These statues were commissioned by Mussolini to decorate The Mussolini Forum, which was to house the 1944 Olympics before WWII intervened. As decorative sculpture they're not bad; as art...well, what do you think? Me, I'd say no. The technique is highly professional rather than artful and there's no transcendant quality in them.
The statue above (topmost) put me off when I first saw it because it seemed to be glorifying a bully or a thug. I think I was wrong because beefy guys like that have been universally admired since the 30s. Even Captain Marvel (above) used to look that way. If you look close you can see some sensitivity and intelligence in the statute's eyes.
These are physiques (above) that I associate with Nautilus machines. I used to think exercizes that emphasize specific muscles were a modern invention but you see figures like this in Rubens and other old masters so I guess I was wrong. The guy on the right looks like he had a killer bowel movement.
I like this kind of manly sculpture (above) but the hair looks like it was turned out without much thought. Zaidenberg (the 40s how-to-draw author) used to draw deco hair like that using charcoal to make quick, chisel strokes. Ruskin in "Seven Lamps of Architecture" warned against schlocking what appears to be unimportant details like the hairline. I think he was right.
