Good program for boosting energy?

Hi guys! Can anyone recommend what program would be best for feeling more energetic? I don't have big goals regarding changes in appearance (wouldn't want to lose nor gain weight, just firm up), I do work out regularly (but moderately) and I think it does help me in general to feel less tired but I would like to do more, if there is any program aimed specifically at that. What are your experiences? Did you feel a significant change in energy level after finishing a certain program and which one? Thanks!
