You would use the style (arch, leg position, whatever) that would allow you to use the most weight. Because....... It just seems a little stupid not to doesn't it??
All of the flat back, arch back, legs, no legs arguments go away with the question of using more weight.
If you are able to use more weight you get better development. The couple of inches here or there will not make up for putting yourself in a position where you can use 20 - 30 more lbs on a regular basis.
There is another factor, when you increase the rotation about the shoulder joint under a load you increase the chance of injury.
Here is how to decide what bench press style is best. Does it -
- decrease you range of motion?
- Is the range of motion less about the shoulder joint?
- Does it put you in the best position to lift the most weight?
- Is it putting you in the best position for injury prevention?
And that is about it. Some people like wider grip, some people like a closer grip. I think that is more of a preference of personal style than right or wrong technique.
As far as actual grip on the bar goes. I know people who use a regular grip and a thumbless grip. If you use a thumbless grip make sure your spotter is really on their game, as the bar can roll out of your hands.
Personally I use a regular grip wrapping mt thumb around the bar. I like to rotate my hands a little so that the bar is in the "butt-crack" of my palm. Again, that is more of a style thing that a proper technique thing. I feel that it keeps the stress off of my wrists and creates a better line of force.
I am going to side with Evo on the "if your bench press is big, your chest will be to" type statement.
And
is there any benefit to the "plop down and push" form?
I do not know what the "plop and push" is?? Sounds like a bowel movement to me.
