Answer 2

When we pick up a ball with our palms, we do feel the weight in our forearm as the muscle present in the forearm is actively involved in picking up anything of high weight.  

Explanation:  

• The number of muscles present in the forearms is myriad and they all participate in lifting weight.
• The flexors are present along with extensors of the fingers, the brachioradialis is presently associated with the elbow, the supinators and pronators help in turning the hang in a different direction.
• All of these muscles work to help lift heavy things and hence the weight can be felt by all.
