Logan may have been amused, but James wasn't. No, this was all quite serious to the big man. He had perhaps deliberately provoked the kid, but also to prove a point. The ignoring of his blustering was also to prove another, equally important, point. That such things not only wouldn't get him anywhere, but that they wouldn't even be acknowledged. James was not going to try and force him into doing anything, but when the kid finally settled down and began doing situps he made a mental note of it.
By the time he called a halt to the situps, even he was starting to feel the workout. A welcome feeling, and a quick stretch as he got to his feet produced several pops from his back. "Come on. Another quick jog." And he'd snag his shirt, taking off even farther into the property at the fast pace he'd set earlier. It seemed Karr's earlier behavior had been forgotten, because James had not changed his manner towards the kid, at all.
Another couple of minutes at he fast jog would bring them to what looked like one hell of a rope course. It was constructed with steel cable instead of rope, though, given some of the people who had to use it. "No claws. Either of you." Looking at Logan for a moment, before glancing to Karr. "Took a hell of a long time to construct this, so no cutting it up." Though he was fairly sure Karr's claws couldn't damage it, but better safe than sorry. Though he didn't start in on it immediately, giving them a quick breather once again. And perhaps to assess Karr's reaction to this newest item.
