calorie consumption

I started to calculate how much will I burn calories when lifting.
The lifting part seems to be easy,
Energy = mgd, in Joules, multiply by .0041
to get kilocalories

where m = the weight in kg
g = earth’s gravity 9,81 m/s2
d = distance in metres.

How should I calculate the energy needed in
lowering the weight? The power needed is slightly less but how much?

LOL. Archie, we’re not going to do your thermodynamics homework for you. Go away.
