How many lbs is a horsepower?

Is 5 watts per kg good?

If everything goes well, I should hit 5+w/kg. For most (not all), the key to 5 w/kg is to lose weight. There is definitely a limit as to how much power you can build, but for most, weight is the factor that will bring the most gains. No where near 5 W/Kg but I would say that being light will be a key contributor.
