When maintenance of the desired weight is the goal with minor muscle toning, there are also specific exercises out of the 12 varieties that are proven effective for this. If increased in flexibility is the main objective, the whole fitness regimen can be tailored for this. If increased speed and stamina is the desired effect, there are exercise steps that can be given more focus to achieve the wanted results.
