Form (exercise)

Form is a specific way of performing a movement, often a strength training exercise, to avoid injury, prevent cheating and increase strength.

'Proper form'

Exercises or drills in sport have a recognized way of performing the movements that have two purposes:

Avoiding injury

By using proper or 'good' form, the risk of injury is lowered. A lack of proper form commonly results in injury or a lack of effect from the exercise being performed

Maximize benefit

Good form ensures that the movement only uses the main muscles, and avoids recruiting secondary muscles. As a muscle fatigues, the body attempts to compensate by recruiting other muscle groups and transferring force generation to non-fatigued units. This reduces the benefits in strength or size gain experienced by the muscles as they are not worked to failure.

Exercise (options)

The owner of an option contract has the right to exercise it, and thus require that the financial transaction specified by the contract is to be carried out immediately between the two parties, whereupon the option contract is terminated. When exercising a call option, the owner of the option purchases the underlying shares (or commodities, fixed interest securities, etc.) at the strike price from the option seller, while for a put option, the owner of the option sells the underlying to the option buyer, again at the strike price.

Styles

The option style, as specified in the contract, determines when, how, and under what circumstances, the option holder may exercise it. It is at the discretion of the owner whether (and in some circumstances when) to exercise it.

Forma

Forma is a Latin word meaning "form". Both the word "forma" and the word "form" are used interchangeably as informal terms in biology:

Formwork

Formwork is the term given to either temporary or permanent molds into which concrete or similar materials are poured. In the context of concrete construction, the falsework supports the shuttering moulds.

Formwork and concrete form types

Formwork comes in several types:

Homogeneous polynomial

In mathematics, a homogeneous polynomial is a polynomial whose nonzero terms all have the same degree. For example, is a homogeneous polynomial of degree 5, in two variables; the sum of the exponents in each term is always 5. The polynomial is not homogeneous, because the sum of exponents does not match from term to term. A polynomial is homogeneous if and only if it defines a homogeneous function. An algebraic form, or simply form, is a function defined by a homogeneous polynomial. A binary form is a form in two variables. A form is also a function defined on a vector space, which may be expressed as a homogeneous function of the coordinates over any basis.

A polynomial of degree 0 is always homogeneous; it is simply an element of the field or ring of the coefficients, usually called a constant or a scalar. A form of degree 1 is a linear form. A form of degree 2 is a quadratic form. In geometry, the Euclidean distance is the square root of a quadratic form.

Homogeneous polynomials are ubiquitous in mathematics and physics. They play a fundamental role in algebraic geometry, as a projective algebraic variety is defined as the set of the common zeros of a set of homogeneous polynomials.
