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.
A set is how many times you are going to lift and then take a break. So if you lift the weight five times, take a break, and lift again you will have done two sets. The five times would be your reps. My coaches like to write the workout like so: Squat 3x2, Bench 2x5, and so on.
