Kangaroos are well-known for their muscular bodies, with male kangaroos, especially red kangaroos, being extremely muscular. Their muscle build is a result of natural processes and habits in their daily lives. Kangaroos use their legs with large stretchy tendons to hop at high speeds over long distances in their native Australian terrain. This constant hopping builds up serious leg muscles over time. Additionally, male kangaroos often engage in brutal boxing matches, pushing, punching, and scratching each other, which contributes to their muscular strength and mass. The importance of dominance also plays a role, as female kangaroos are attracted to muscular males, granting the strongest males the right to mate.

What You'll Learn
Male kangaroos are genetically predisposed to be muscular
Male kangaroos are known for their muscular bodies, with some sources claiming that they can resemble human bodybuilders. Their large size and powerful build are a result of several factors, including genetics, behaviour, and diet.
Genetically, male kangaroos are predisposed to be muscular, with about 50% of their body weight consisting of pure muscle. This gives them a naturally "buff" appearance. Red kangaroos, in particular, are known to have extreme muscles. Their unique gait, or way of moving, also contributes to their muscular build. Kangaroos power their movement with their hind legs and large back feet, which contain strong muscles and tendons. The Achilles tendon, in particular, helps them generate energy to hop long distances, covering 25 to 30 feet per leap and jumping up to 10 feet in the air.
Male kangaroos also engage in frequent fighting and boxing matches to establish dominance and access to females. These fights are intense and often brutal, involving pushing, punching, and scratching. The dominant male is usually the only one who mates, so their fighting abilities and physical strength are crucial to their reproductive success. The very act of fighting also helps build muscle mass, as the energetic exertion results in increased musculature.
In summary, male kangaroos are genetically predisposed to be muscular, with a high percentage of their body weight consisting of muscle. Their unique locomotion and frequent fighting behaviour further contribute to their muscular development, resulting in the impressive physical strength and size observed in many male kangaroos.

Fighting for dominance and mating rights
Male kangaroos are known for their muscular bodies, and they use these muscles in fights for dominance and mating rights. The dominant male is usually the only kangaroo in the group who mates with the females, so they fight to win these rights. These fights are often brutal boxing matches where males push, punch, and scratch each other. The single most powerful male usually wins these battles, so being strong and toned is essential.
Kangaroos have the strongest and most muscular legs of any hopping animal. Their unique gait, where they power their movement with their hind legs and large back feet, contributes to their muscular build. The Achilles tendon in their hind legs provides energy with each jump, allowing them to cover 25 to 30 feet per leap and jump up to 10 feet in the air. This constant leaping while supporting their large bodies builds their leg muscles.
In addition to their physical attributes, kangaroos also have a high aerobic capacity, comparable to athletic placentals like dogs. This allows them to travel at moderate speeds with a lower relative cost of energy expenditure. The combination of their muscular build and aerobic capacity makes kangaroos powerful and agile fighters.
The preference of female kangaroos for muscular males further incentivizes male kangaroos to develop and showcase their muscles. This preference may be due to the perception of muscular males as dominant and strong, increasing the chances of successful mating and offspring survival.
Overall, the combination of fighting for dominance, mating rights, genetic predisposition, and the appeal to females contributes to the impressive muscularity of kangaroos, particularly the males of the species.

Kangaroos' hopping gait
The kangaroo's hopping gait is a distinctive form of locomotion that has evolved over millions of years. The kangaroo is the only large mammal to use hopping on two legs as its main form of locomotion. The evolution of this gait has resulted in kangaroos having the strongest and most muscular legs of any hopping animal.
The kangaroo's hopping gait allows them to cover large distances quickly, at a rate of about 25 kilometres per hour, and they can jump up to 10 feet in the air. This form of movement is made possible by the powerful muscles and tendons in their hind legs and large back feet. With each jump, the Achilles tendon that runs down the hind leg provides energy, which is distributed as the muscles contract and push the legs away from the body.
The evolution of the kangaroo's hopping gait has been the subject of scientific research and hypotheses. One theory suggests that hopping evolved as an adaptation to a drier climate and the spread of grasslands, allowing kangaroos to efficiently cover large distances in open habitats. However, geometric modelling suggests that extinct cousins of modern kangaroos could also use a diverse range of gaits, indicating that the ability to hop may have existed for far longer than previously thought.
The musky rat-kangaroo is an interesting exception within the macropodoid family, as it is the only member that does not hop. Instead, it bounds over obstacles on the forest floor, with its hind feet and forefeet moving together in synchrony. By studying the movement of this rare macropodoid, researchers can gain insights into how and when the distinctive hopping gait of kangaroos evolved.

Kangaroos' diet
Kangaroos are herbivores and primarily eat a variety of plants, including grasses, shrubs, flowers, leaves, ferns, and moss. They also occasionally eat insects. Kangaroos have been observed to regurgitate their food, chew it again, and swallow it before it is digested—a process known as rumination. This, along with the moisture content in the plants they eat, allows kangaroos to survive for long periods without drinking water.
Kangaroos have chambered stomachs, similar to cows, which means that they can regurgitate their food and chew it as cud before swallowing it again. However, this behaviour is much rarer in kangaroos than in ruminant animals like cows. The digestion process in kangaroos also differs from that of cows in that it does not produce as much methane, resulting in lower emissions.
Kangaroos can be fed pellets designed to supplement their diet and ensure they get the necessary nutrients. These pellets are high in vitamin E and provide a unique natural antioxidant cocktail.

Female kangaroos' preference for muscular males
While it is not possible to ask female kangaroos what they look for in a mate, researchers have ways of theorizing an animal's motivations. According to several sources, female kangaroos are indeed attracted to male kangaroos with more muscles. Male kangaroos with larger forearms in proportion to the rest of their bodies are chosen as mates by females, and males with the biggest forearms have more opportunities to mate.
Male kangaroos also engage in brutal boxing matches and fierce fights for dominance, and the dominant male is usually the only kangaroo in the mob who mates with the females. The single most powerful male usually wins the battle, so being the strongest and most toned pays off.
Male kangaroos also strike poses to show off their muscles to the females, and they flex their biceps to impress potential mates. However, it is not currently possible to determine whether or not such behavior is a conscious move to show off to female kangaroos, as humans do not fully understand animal consciousness. Nevertheless, female kangaroos are drawn to larger, more muscular kangaroos, and the biggest and strongest males get the right to mate with females.
In addition to fighting, male kangaroos bulk up through diet and exercise. They gain strength from playful sparring matches and other muscle-building exercises, such as hopping along the ground and pushing off the ground with their forearms. They also need plenty of rest to recover and a diet high in protein and other nutrients to maintain their muscles.
