eli5 how does more muscle make you able to lift heavier stuff
In: 3
muscles are like elastic, the more you toughen them (i.e strength training gets more muscles and denser muscles), the less elastic the muscles are. If you have elastic arms, you cant pick up a box, the box stays on the ground and your arms would stretch like the comic book guy, but if you have tight and tough muscles (elastic), then your arms stay in shape and you can lift the box.
Now a tougher way to write it
Think of a rope that has infinite stretching capability, stretching never gets tougher or easier, and if you have a tough rope, it takes a lot of effort to stretch, while a weak rope takes little effort to stretch. I want to use this rope to pull a 100kg box. If I use the tough rope, it will not stretch and it will pull the box. If i use the weak rope, it will stretch and I cant move the box.
When people work out, they don’t just go from o to 0 to O, they go from 0 to (|). They did expand, but there is also more inside that O. The density of the muscle increases, and then when it gets too dense it starts expanding outwards before redensifying.
