Answer 1

You could lift everyday and probably gain close the same amount of muscle or strength. However connective tissues have a far lower blood supply and repairs itself much more slowly. This is the reason people in physical jobs have a ton of injuries. These are generally overuse injuries like tendonitis, cartilage damage, etc – all connective tissue injuries. When not given enough rest these connective issues get inflamed and even separate from the muscle and/or the bone.
