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.
One set is effective, though two to three sets may be better, according to limited evidence. A set is a specific number of repetitions of an exercise; we recommend repeating each exercise eight to 12 times. Your body needs at least 48 hours for recovery and repairs between strength training sessions.
