Fought how? He's tightly bound by (one presumes) high-tensile steel cables. You know, like the things that hold up suspension bridges? What's he supposed to do, flex his manly boob muscles? Besides the fact that after a few days without blood, he's probably gonna lose his strength, which isn't that super in any case.

Um... with everyone wondering how he's gonna get out, here's an idea. HE'S GOT SUPER STRENGTH. If he fought everyday for an hour, it would be absurd if he couldn't break free.
If I remember rightly, he actually broke through a wooden panel to reach round to the lock in 'Warzone', and he had free use of his limbs.
Everything buckles adventurly and, when Angel was imprisoned by Gunn, it took a few hours, but he finally busted through the METAL WALL!!!!
