Mesh Rigging deforms parts on the mesh while animating?

If you see around the chest region as my avatar walks it pulls and stretches areas around the mesh. How can I prevent this from happening? None of the "cubes" are supposed to stretching at all. They should be acting as if a prim was just attached to a bone in sl.

 

I would like to also mention I'm very new to mesh and have been able to get the rigging mostly done. Just can't fix this deforming issue.

 

Any help would be much appreciated thanks :)!

 

If there is anything else you need for me to post please do ask~

Weighting the vertices of each box 100 % (1.0) to a single bone should prevent any distortion.

Judging from the image, it could also be just the usual camera perspective distortion though.
