Thanks for the tip! Ill try to breath more!
I think your circulatory system isnt sending enough oxygen to your muscles!
*Breathes* WOW THIS IS SO EASY NOW! Thanks for the tip!!!
The circulatory system is not able to get enough oxygen to the muscles.
He needs to breath more so that the oxygen can travel though the circulatory system to aid the muscular system.
Now that the muscular system has a sufficient amount of oxygen reaching it through the circulatory system he can easily lift the weights.
