Perhaps the next iteration of such tracking would be values for related series of objective measurements that should improve with the investment of time. Continued exercise should yield improvements in weight, speed, endurance, etc (at least for an individual as young as the OP).
Malcolm Gladwell often trumpeted "deliberate practice." Does the OP receive feedback regarding the quality of his musical practice or the form displayed during physical exercise? Does that yield greater gains per time?
More (most) importantly, what are the GOALS of these activities? The ultimate assessment would be the extent to which such data, discipline, and tracking actually spark progress in the desired direction.
