Studies of kangaroos and wallabies have demonstrated, beyond the minimum energy expenditure required to hop at all, increased speed requires very little extra effort (much less than the same speed increase in, say, a horse, dog or human), and the extra energy is required to carry extra weight. For kangaroos, the key benefit of hopping is not ...
Male kangaroos bulk up the same way humans do, through diet and exercise. Not only do the males gain strength from playful sparring matches, but they also engage in other muscle-building exercises.
Kangaroos conserve energy between hops using elastic mechanisms. From previous experimental studies on large animals, it was noted that during active locomotion mammals save much of the energy they would otherwise need for running by means of elastic structures in their legs.
Macropodidae is a family of marsupials that includes kangaroos, wallabies, tree-kangaroos, wallaroos, pademelons, quokkas, and several other groups.These genera are allied to the suborder Macropodiformes, containing other macropods, and are native to the Australian continent (the mainland and Tasmania), New Guinea and nearby islands.
Red kangaroos are notorious for getting into scuffles with other roos. As Animal Planet notes, during a fight, the animals will deal out some nasty kicks while supporting all of their body weight ...

Kangaroos do not have a "unique" ability to store strain, or potential, energy in their tendons. This fancy terminology is just a way to say that tendons work like springs: stretch them out and then they go back - like a pogo stick. All animals with compliant tendons store energy in their tendons.
The red kangaroo (Osphranter rufus [5]) is the largest of all kangaroos, the largest terrestrial mammal native to Australia, and the largest extant marsupial.It is found across mainland Australia, except for the more fertile areas, such as southern Western Australia, the eastern and southeastern coasts, and the rainforests along the northern coast.
