    They’ve made themselves, and that their fitness now

  1. fitness

    Fitness generally refers to the condition of being physically fit and healthy. This involves a combination of regular physical exercise, balanced diet, and adequate rest. It includes elements such as cardiovascular endurance, muscular strength, flexibility, and body composition. In the context of evolutionary biology, fitness refers to an organism's ability to survive and reproduce in its environment, effectively leading to the passing down of its genes to the next generation.

Webster Dictionary

  1. Fitnessnoun

    the state or quality of being fit; as, the fitness of measures or laws; a person's fitness for office


  1. Fitness

    Fitness is a central idea in evolutionary theory. It can be defined either with respect to a genotype or to a phenotype in a given environment. In either case, it describes the ability to both survive and reproduce, and is equal to the average contribution to the gene pool of the next generation that is made by an average individual of the specified genotype or phenotype. If differences between alleles of a given gene affect fitness, then the frequencies of the alleles will change over generations; the alleles with higher fitness become more common. This process is called natural selection. An individual's fitness is manifested through its phenotype. The phenotype is affected by the developmental environment as well as by genes, and the fitness of a given phenotype can be different in different environments. The fitnesses of different individuals with the same genotype are therefore not necessarily equal. However, since the fitness of the genotype is an averaged quantity, it will reflect the reproductive outcomes of all individuals with that genotype in a given environment or set of environments. Inclusive fitness differs from individual fitness by including the ability of an allele in one individual to promote the survival and/or reproduction of other individuals that share that allele, in preference to individuals with a different allele. One mechanism of inclusive fitness is kin selection.

Examples of fitness in a Sentence

  1. Warren Higgs:

    [ The tricycle ] will help me regain my fitness, then I can get back to life hopefully.

  2. Winning sentence, 1990 Bulwer-Lytton bad fiction contest.:

    Delores breezed along the surface of her life like a flat stone forever skipping along smooth water, rippling reality sporadically but oblivious to it consistently, until she finally lost momentum, sank, and due to an over- dose of flouride as a child which caused her to suffer from chronic apathy, doomed herself to lie forever on the floor of her life as useless as an appendix and as lonely as a five-hundred pound barbell in a steroid-free fitness center.

  3. Blogilates Cassey Ho:

    As a fitness instructor and online personality, people expect me to look a certain way. So when I take a selfie and people see that my butt isn’t huge and I don’t have a defined six-pack, they think there’s something wrong with me, the thing is—my physical appearance alone does not dictate how strong I am nor does it say anything about how good of a trainer I am. It’s frustrating when people try to align your worth by your looks.

  4. Victoria Mendoza:

    Setting aside an hour for a virtual fitness trainer session allows me to not stray from my fitness goals and correctly do my workouts, even with limited machines.

  5. Nicole Spartano:

    From other studies, we know that exercise training programs that improve fitness may increase blood flow and oxygen to the brain over the short term, over the course of a lifetime, improved blood flow may have an impact on brain aging and prevent cognitive decline in older age.
