#27 - Quem decide quando você pára uma série: o músculo, o cérebro ou a consciência?

Neste episódio vamos raciocinar um pouquinho em cima de uma dúvida que talvez tenha passado pela sua cabeça em algum instante mas você nunca deu seguimento depois. Você já se perguntou se quando você tá lá treinando, fazendo uma série de algum exercício, você pára por causa do músculo falhando, do cérebro mandando parar o estresse ou é a sua consciência botando um limite autodeterminado?Vamos descobrir..
