The location of the hole (perforation) in the eardrum also effects the degree of hearing loss. If severe trauma (e.g. skull fracture) disrupts the bones in the middle ear which transmit sound or causes injury to the inner ear structures, the loss of hearing maybe quite severe.
1 Resting 1-3 minutes between sets is probably ideal for you. 2  The higher your training intensity is for a given exercise and/or the more demanding it is on your body, the more you should stay nearer to the 2-3 minute range.
Too little rest and you quickly fatigue the working muscle. With so many schools of thought on different training theories, how much rest time should one really take in between sets? I'm sure that you've heard 30 seconds, 45 seconds, 60 seconds, and so on. Well, after over 3 years of training and trying nearly all of the theories out there, I've come to the conclusion that there is no set amount of time one should rest in between sets.
