M\u016f\u017eete si to p\u0159edstavit, jako byste st\u0159\u00edleli z d\u011bla, zat\u00edmco sed\u00edte v kajaku. Slab\u00e9 j\u00e1dro vykouzl\u00ed eskym\u00e1ka. A siln\u00e9 j\u00e1dro v\u00e1s udr\u017e\u00ed v suchu.<\/p>\n\n

Jin\u00fdmi slovy, z\u00e1kladn\u00ed svaly jsou pro \u017eivot nezbytn\u00e9 a v\u0161echny pohyby, kter\u00e9 vid\u00edme navenek, vych\u00e1zej\u00ed z nich.
