What about CMS (electrostimulation with electrodes), can it raise the energy level and such like raw exercising? I'm becoming very intrigued about CMS, as a 'low energy individual'.
Last time I researched the topic, the conclusion was the level of simulation was too low in comparison with a real exercise. It still has its use in physiotherapy and rehabilitation though.
My answer to low energy is coffee. Do stupid things faster (c)!
