Applied Physics: Weight-Lifting "Work"
OK, sorry, this may be in the wrong place... but where would you post something like this?
This may be too simple, but I cannot get my mind wrapped around this. I need to lose weight and I want to be able to 'quantify' the calories I burn. If I am bench pressing, and I raise 100 lbs. through a distance of 24 inches, how much 'work' have I done, in terms of calories burned? We can neglect all the variables such as efficiency, speed of movement, work done in 'lowering' the weight, etc. I just want to know what the minimum work (change in potential energy) is, in terms of calories required.
My goal is to be able to say, "I want to burn X calories per day. How much weight do I have to move per day (through the 24" distance) to burn at least that many calories?"
Thanks in advance for your help.
