The Scientific Secret of Strength and Muscle Growth

[00:00] We all have a fascination with muscles and

[00:04] feel better, or look like superman; and there

[00:08] regimens to get this done.

[00:10] But what if I told you that it was out of

[00:14] entirely holding you back?

[00:16] Conversely, what if there was a secret out

[00:21] The truth is: your muscle size has a limit.

[00:24] Sure, it may seem obvious when you hear it,

[00:28] of a protein called Myostatin, which determines

[00:33] And this limit is different for everyone depending

[00:37] As a muscle reaches this limit, myostatin

[00:40] But if the myostatin itself is limited or

[00:46] This phenomenon was first noticed in Belgian

[00:49] These cows developed 2-3 times more muscle

[00:54] that they had a deletion of the gene GDF-8,

[01:00] As a result, without any exercise or special

[01:05] Similar cases have been documented in dogs,

[01:10] lacking the GDF-8 gene.

[01:13] These findings have helped scientists understand

[01:17] struggle to.

[01:18] Lower levels of myostatin = more muscle mass.

[01:21] In fact, some studies have even shown that

[01:25] lower levels, or even entire deletions of

[01:34] As such, perhaps many champion bodybuilders

[01:41] Eventually, it may be possible to develop

[01:45] Of course, it's a double edged sword; On the

[01:53] On the other hand, the potential for abuse

[01:58] But, the prospect of seeing a real-life human

[02:09] It's hard to say.

[02:10] Regardless, be weary of anybody selling or

[02:33] limits through training and hard work.

[02:35] But, what if you could punch as hard as Superman?

[02:38] Our friend Jake over at Vsauce3 has the answer

[02:43] you definitely need to check out.
