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.
Weight lifting may also impose heavier demands on your muscles, thus necessitating a full 48-hour recovery in between sessions. If you're new to lifting, you may find yourself quite sore after your first few sessions. In that case, you may even want to wait 72 hours between weight workouts. If you're doing a combined cardio/weight routine, then you will need to strategize to maximize the effectiveness of both modalities and avoid over-training.
