What is the rhythm of acrostic poems?

A double acrostic poem is the same as an acrostic poem, except that the line ends with the same letter that it starts with. E.g:

Alexandra,

Nelson,

New Brighton

Is a double acrostic poem of the Word 'Ann'.

Hears a better idea with pulse

People start with a pushup

Usually work out due to eating fondu

Loosing weight is not accidental

Slowly reducing their big old behinds

Every step seems like mile when people only work out once in a while
