The correct spelling of the word "isometrical" is often debated due to its similarity to "isometric" and "isometric." However, the pronunciation of the word provides a clue to its correct spelling. The IPA phonetic transcription for "isometrical" is /aɪsəˈmɛtrɪkl/ where the stress is on the second syllable. The "-trical" ending indicates a relationship to an art or science, such as is seen in "geometrical" or "metrical." Therefore, the correct spelling of the word is "isometrical."
Isometrical is an adjective that relates to or refers to a form of exercise or physical activity that involves contracting muscles without altering their length, resulting in little or no movement at the joints. It is characterized by the exertion of effort or force against resistance, such as an immovable object or one's own body, in a steady and sustained manner. This type of exercise is primarily focused on strengthening and toning a specific muscle group or multiple muscle groups simultaneously.
Isometrical exercises are typically performed using static positions or holds, where the muscles are contracted and tensed for a specific period of time, usually between 5 to 10 seconds. Examples of isometrical exercises include planks, wall sits, and push-up holds.
This term can also be used in a broader context outside of the realm of physical fitness. In this sense, isometrical can refer to any process or situation that remains constant or unchanging, without any change in movement, shape, or form. It implies a state of equilibrium or stability in which the characteristics or properties of something are maintained consistently over time.
In summary, isometrical pertains to a type of exercise that involves muscle contraction without significant joint movement, as well as the idea of stability and constancy in a broader context.

The term "isometrical" comes from the combination of two root words: "iso-" and "metrical".
1. "Iso-" is a prefix derived from the Greek word "ísos", meaning "equal" or "same". It is used in many scientific and technical terms to denote equality or sameness, such as in "isothermal" (equal temperature) or "isochronous" (equal time).
2. "Metrical" is derived from the Latin word "metrum" and the Greek word "metron", both meaning "measure" or "meter". It relates to the concept of measurement or proportion, often used in reference to poetry or music.
Combining these two roots gives us "isometrical", which generally refers to something that has equal or consistent measurements in all dimensions.
