The index finger could be used to flip more pages often, of do finger excercises.

You should rule out the possibility of "skeletal" damage.
It is possible that you can not bend it properly simply because the bones does not allow this easily.
I do not think flipping pages would actually do the trick of getting muscles back into shape.
Try some rubberband exersizes where you use your index finger to stretch the rubber by bending it. put a nail in a plank of wood, then put the rubberband over the nail, and start stretching. If too easy with one rubberband, then use two or more.
You can also go to a toyshop or even a petshop and find a small softish ball to squeeze. Make sure you squeze it with your indexfinger, and not only with the other fingers.
Best of luck, and regards..

it is preferably better to stretch before you work out rather than after working out because your muscles need to be warmed up so you'll not feel uneasy working out. also stretching before working out can minimize the excessive working of the muscles.
Never, you always have working muscles. Eg: your core muscles work to keep you standing/upright.

Your limbs burn when you exercise because you are working the muscles hard. Even when your working out, like lifting weight even if its lower than what you can do after so many reps your limbs will start burning because of the muscle.
We need involuntary muscles because then every day we don't have to think how our heart is working .

standardization is important because it helps to determine whether the machine is set and working properly or not.
Core exercise is important, because it help strengths the core muscles. Core muscle training will also strengthen other muscles during the training.
involuntary muscles
When you work the muscles gets stronger and healthy.
The muscular does keep your body warm because say for instance you where working out. When working out you sweat, to cool you off and shiver to warm you up so your working out working your muscles.
