ATP- Because ATP Is Being Built Uo And Stored In Your Bodys Cells 

During the resting phase, the amount of the ATP (adenosine triphosphate) increases in the body. The Breaking down of bonds present in ATP results in the formation of ADP (adenosine diphosphate) and generates energy.

In resting stage, the  body generates the energy to be used after this. So, the ATP molecules are conserved. So, in the resting phase, there would more ATP than ADP.
