my problem is that my right arm is weakening. there is a definite difference in the shape of both my ars i mean when i puff out my muscles the left bicep big and hard while my right one is soft and round. the viens are also differently layed.the veins in the left fore arm are dense and in the right one only 2 are visible. note: i am right handed.
can any1 tell me why this is so? when i arm wrestle with my friends i can easily beat them with my left hand bt i always lose with the right.
