Unfourtunatly, this doesnt really help to reduce sagging skin. Many people usually go to get surgery if the sagging skin is very serious. This is something that would have to be evaluated by a doctor or plastic surgeon.
Do as many as it takes to create muscle failure. Muscle failure is the sensations of not being able to do any more of a particular task. You should feel like rubber when done. The key to building muscle is not in doing the task every day. Your body builds muscle during rest, not during exercise. YOu must work the muscle groups to exhaustion(aka failure) then give them a minimum of 48 hours rest before resuming the exercise. Muscle building occurs during REST. To build bulky muscles quickly you need to do lower reps with higher weights. Doing a 100 lunges everyday is not as effective as 20 squats with 70% of max weight with a 48 hour rest. Again, muscle building occurs during REST.

Triggering of the muscle action potential occurs after acetylcholine binds to chemically-gated channels in the end plate membrane.

CRAMPS
Lactic acid builds up and causes muscle burn.
This particular reflex is autonomic as the affected muscle, constrictor pupillae muscle, is a smooth muscle and not under conscious control. Typically if you can consciously contract the muscle, any reflex associated with that muscle is somatic in nature.
Flexion
Relaxation of a skeletal muscle usually involves the Golgi tendon proprioceptors.
your muscles moves, moving ligaments and tendons
