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.
After every warm up set, except the final 1 repetition, rest between 45 and 60 seconds. After the last repetition, rest as long as you normally would for that amount of weight. Under most circumstances, this is an ideal warm up sequence.
