There are many exercises that you can use. Go through some of the ones online and see if they will meet your needs.
Isometric
The strongest muscle contractions are normally achieved by increasing the stimulation up to the maximal stimulus. There are various classifications of contractions, including eccentric and concentric.

Eastern City Dwellers
Probably Yugoslvia. Incidentally, resistance in Germany was very difficult to organize and was weak.
By strongest moves, Emboar. By choosing by type resistance, Samurott. And Serperior is the WORST choice. He has the most weaknesses, and he can't learn as strong moves as the other starters.
No. Steel and mercury are both good conductors (low resistance). Diamond and rubber are both insulators (high resistance).
Almost any exercise is beneficial to the skeletal system. The ones that build the strongest bones are the ones that are weight-bearing. Add to that resistance training and you will build stronger bones. Be sure to also have a good diet and drink plenty of water. One of the easiest and best exercises that almost everyone can do is walking.
It really depends on what kind of strength you are looking for, a triangle is the strongest shape when rigidity is what is needed (so when you want to have a strong cantilever structure or a general structure that can resist a variety of stresses). It's difficult to say what might be the second strongest shape in such circumstances, but maybe a triangle that is not equilateral, but this is an over simplification. An octet-truss is the strongest structure for cantilevering because of the strength of the triangle However if its 'hardness' you're looking for, or resistance to purely compression, a tessellation of hexagons is your strongest shape, and therefore perhapse an irregular hexagon is your second strongest. A lorimerlite framework is the strongest truss under compression because of the strength of hexagons.
Statistically, Charmander is the strongest starter Pokemon to take. However Bulbasaur will get you through the first two gyms easily, whilst Squirtle has the best resistance to your Rival's choice. All three starters are valid choices however, and it is easy to compensate for their weaknesses with your catches later on.
Nichrome wire has such high resistance that it is used to convert electrical energy into heat. Many heating elements are made from nichrome. Copper wire has the best conductivity, for the price, of any metal.
Because that's the easiest way to make them, and the strongest. EDIT: Also the circular shape allows for a smoother flow of liquid within the pipe and less resistance.
