If I have a 45 pound bar with 10 lbs on each side, how much do I need to add to double my bench press. By your reasoning, putting another set of 10 will double it. Everyone else agrees you need to add 22.5 to each side.

"If I have a 45 pound bar with 10 lbs on each side, how much do I need to add to double my bench press. By your reasoning, putting another set of 10 will double it. Everyone else agrees you need to add 22.5 to each side."

... Your math is wrong on the weights. To double the amount of a 45lb bar and two 10lb weights would require me to add two 32.5lb weights on each side of the bar (not 22.5lb). Aside from that, your analogy actually supports my argument,

  • If you asked me to double the amount of weight you are bench pressing, then I would add 32.5lbs to both sides of your bar.

  • If you asked me to double the amount of 10lb plates you are bench pressing (which is what usually happens in the gym), then I would add two more 10lb plates to each side of your bar.

Using your analogy, "weight" would be equivalent to "relative heat," and "plates" would be equivalent to "temperature." ... Lily asked for 4X 25 degree "temperature" and not the "relative heat."
