Weight, Pull and Push: week 3

The reference for the weight lifting exercise. I took an idea from this  example and developed into the weight lifting sequence.

It was my second time of animating the heavy object lifting sequence.There is my first animated sequence, which I drew for my old animation story 2 years ago.

Animating second time, I tried to analise my previous mistakes to create the realistic struggling of the character this time.
