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.
1 Upper and lower body muscles groups in combination. 2  For example: Barbell Deadlift + Barbell Squats + Pushups. 3  When you do a giant set, you can rest up to one minute between exercises. 4  However, I recommend you try to keep your rest-time around 30 seconds.
