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.
So the low down on reps is 4 to 6 for all heavy sets. Warm up sets and intermediate can be 8 to 10 reps, but to get the muscle stimulating benefit of weight training, you must use lower reps to create enough of an overload. The amount of heavy, intense sets per exercise will be between one and three sets, depending on the order of the exercise.
