The key in weight training for boxers is to develop explosiveness. This means doing 6 to 8 reps of each exercise with the heaviest weight you can handle. Do 3 sets of each and vary the exercises so your muscles don't plateau. Alternate days between core and weight training.
Later on, the grey wolf was put on the Endangered Species List, and were protected. But now, people in states such as Alaska, Utah, Idaho, and Montana shoot wolves, gas pups in dens, sterilize alphas, poison wolves, and skin them.
Gray wolves are endangered because of  habitat loss and poaching. People are afraid of wolves and thus tend to paint them as being villainous animals. Ranchers would like to see wolves eradicated because wolves sometimes prey on livestock. Grey wolves are not endangered, as by the ESA. There is no poaching only legal hunting. In Idaho an overpopulation of the non-native species of Canadian Grey Wolf has begun because it was illegally introduced, and has now killed off much of the native species of wolf, the Timber wolf.
