How do Mus­cles Grow?

THE MAN Magazine Cambodia - - Fitness -

Take your bi­ceps on the front your arms as an ex­am­ple. Like all other mus­cles in your body, the bi­ceps are com­prised of tightly wo­ven bun­dles of mus­cle fibers, which are in turn made of mus­cle cells. When you pro­duce a force, such as lift­ing a couch, most of those mus­cle fibers in your bi­ceps are ex­posed to ten­sion (es­pe­cially if your couch has a fold-out bed hid­den in­side). The ten­sion from the weight of that couch stretches the fibers and can cause tiny tears in them -- and when the cells in your mus­cle fibers sense this trauma, they rally the mus­cle-build­ing troops from your body to re­pair the tears. Th­ese mus­cle-build­ing troops in­clude hor­mones, growth fac­tors and white blood cells, which not only re­pair the mus­cle fibers in your bi­ceps, but also in­crease the size of the fibers and the strength of nerves that ac­ti­vate them, so that next time you lift a couch, you strain a bit less. But there are bet­ter ways to make your mus­cles grow than by lift­ing the oc­ca­sional couch. Ul­ti­mately, the tr ick to grow­ing mus­cle is to stress it, al­low it to re­cover while eat­ing enough healthy food to feed the new mus­cle, and then re­peat! With this strat­egy, you can safely build one to two pounds of mus­cle each week -- and since mus­cle takes up much less room than fat, those pounds will look tight and lean. Once you’ve built your new mus­cle, let me know. I have some heavy couches that need mov­ing.
