Who can tell me, run 100 meters. Swing arm. Before and after the set, or with a good wheel?
100 meters swing arm before and after use is better, the wheel swing arm is more suitable for long jump and high jump, 100 meters when the palm straight will increase the speed of the swing arm.
It is a scientific experience.
Not from the beauty of the posture and the role of speed, are good before and after the pendulum.
Before and after the pendulum is a formal posture ... but if you feel before and after the show will affect their rhythm and speed, it is still used to use your arm method. Another point is 100 meters running arm to clamp some, do not tilt to the sides too much will affect the speed also increase the resistance running on the way hand was slap shape straight to reduce the resistance. I'm running and feeling more and more feeling ... very comfortable ...
