muscle workout builds muscle size, cardio is a side effect of climbing stairs. If you use your imagination you can carry weights to make it even more interesting. I like taking the stairs to the 15th floor when I go grocery shopping, then walking back down to my floor.
Sure. If you add weights -> resistance, then you'll build muscle Just body weight? Not much, even with the incline.
Repetition and speed. Remember power = work over time. 100 light reps really quick exerts your muscles just as much as 10 reps of a heavier mass.

100% false.
10 deadlifts @ 100 pounds doesn't take NEARLY as much effort in any measure as 1 rep at 1000 pounds. What you said is so wrong it's laughable.
In a sense of just pure math, if we were using mechanical movers, yes. Forces would be equal. However even then energy required wouldn't be. Energy used is not a linear function as force grows. This can be seen by escape velocity being a function of gravity which derived using the square of the radius of ... (look it up)
What youre stating is that a child carrying a 10 pound book back 528 feet to school every day for 100 days is equivalent work, effort etc to an adult male carrying a 1000 pound block 1 time over that same 528 feet. 10 * 528 * 100 = 1000 * 1 * 528
But it's wrong. This is why the world's strongest men competitors don't increase their strength by doing many lifts of low weight.
e; Another counterexample, setting your car to drive at just the lowest first gear possible over 100 miles doesn't take NEARLY as much gas as doing the exact same distance in the exact same car going any speed higher.
