Would the following concise prayer be effective for amplifying the benefits of exercise? “Augment our workouts and intermittent exercise by applying the benefits to days in between.” What is most important for us to know?

This is a clever and concise summary of what you would like to see happen. And because this is a straightforward benefit to arrange, it will be honored along with other prayer requests, contingent on belief quotient constraints and level of intention being applied from the human end of things, as always. So an honest effort to help one's body by getting exercise is one of the most important self-care measures available. It can be done at no cost other than time and energy. While that requires some discipline, there is a dual benefit of applying oneself because that self-discipline will add intention to empower us to magnify the investment the person is making to have the benefits of the ongoing exercise amplified for their well-being. So it is truly a win-win to request, as long as there is a follow-through by the person taking action in making the effort to carry out some kind of regular exercise program.
