it happens often too i guess. Sports performance really depends on our general mood and how motivated we feel. Usually when i get super hyped up ( be it through music, boxing videos, or whatever ), i perform really well during a training. However, it is not possible for us to feel this way every training, therefore, during certain practices, it is common for us to be tired.
i was like for the first few weeks. did runs when i wasmt training, and now my energy levels have sky rocketed.
With me, I find it correlates with my diet.. I try to stick to a healthy diet, but I occasionally slip up for a few days, thats when I notice I feel sluggish and slow.. That's just me though...
I wan to first try learn of boxing first importance is my body is thin so, i make my body after learn boxing.
