Re: angles
vinylgroover,
Your right in that Muscles basically have two functions-to contract and relax, however what you are failing to look at is that there is more than one muscle to contract in each muscle group. As you should know the tricep for example consists of three different muscles that have orgins and insertions that are unique. Attaching to different areas of the bone allows for stress on that muscle to be distributed among these three muscles unequally. Thus a change in angles changes the distribution of stress on each of the three muscles therefore making it necessary to change angles in order to maximize muscle stimulation of all three muscles. The only way to change the angles is by doing different exersizes for the same body part.

Muscle has two functions, to contract and relax, nothing more. It's as simple as that.
How do you work a muscle at different angles. A muscle can't contract across itself or diagonally or any other way. A muscle simply responds by recruiting the amount of fibres necessary to resist the force against it. It's that simple.
