"Fair enough," Logan gruffed, and got started on it. A good, long workout always did help him clear his head, and thankfully that hadn't changed when all this feral stuff began to surface and nearly take over his life. All he needed was a good workout, some fresh air, and the scent of woods to ground him. Working his body hard also distracted him from thinking of Serena.
All traces of humor were gone from him. He had a good challenge ahead of him, considering that his adamantium skeleton made this the equivalent of someone else trying to do the course loaded down with heavy weights. The scientists who had put the adamantium in him had increased his strength and durability somehow so that the weight of the metal wouldn't cause him to tear his muscles every time he moved, but he wasn't technically super strong. Logan thought nothing of it now as he jumped up to grab the steel cable "rope" and got on with it. Thank God Karr had opted to shut his mouth, he thought idly in the back of his head.
