jetzt hast eh alle meine Tage durch , die ich mir in meiner fadheit in da hackn ausdacht hab . die woche gibts gsd wieder bissl mehr arbeit . <| sep |> Duh . Your guy was black . <| sep |> You have more muscle fibers than before and the force each fiber exerts for the same exercise that formed them will be less than before because of better leverage and biomechanics . It may now require less overall muscle work from auxiliary groups because your main muscle set can now handle it directly . For example , most standing weight exercises are hard at first because you don ' t have strong enough stabilizer muscles . Thus your body engages more muscles to continue standing even though they have poor leverage . As the stabilizers get stronger , you use less amount of total muscles in the body to remain standing . This is my layman ' s understanding from what I ' ve read and personal experience . I believe there is also an aspect of incell energy use and increased effort requiring exponentially more energy , so if you ' re stronger then you need less effort over time due to finishing faster .
