Thread: Back steaks

How come am ending up with chewy back steaks?
if i can take the whole animal , hang it in a chiller for 5 days all meat is tender
Now same type of animal cut out back steaks and i was hanging them over meat rail 5 days later still chewy, mate said lay them flat sinew up. tried that
Is it because am not cooling them enough after cutting them out before i get them home and putting them in a chiller??
