piston AR. 建议您买PWS 的 upper. lower 很好办，自己在家拼一个出来，只要不到
一个小时，而且还能健身。没必要多花$500去买整枪。
现在的DI AR 市场已经非常完善，而BCM/DD/Noveske/Sig/PSA等主要厂家DI 设计的精

发帖数: 4931 | 11 The main cause of muscle cramp is dehydration and electrolyte imbalance. For
most runners, it is only a concern when the run goes beyond three hours.
The risk of cramping is especially high when you run in hot weather, as you
sweat more and lose more electrolyte. Refueling yourself during the run is
important. You need to drink not only water, but sports drinks with
electrolyte, such as gatorade. For longer endurance events, even gatorade
won't be enough. Hammer perpetuem is a good choice. |

Running myth: "Runners should drink as much fluid as possible"
Hydration recommendations have been on a roller coaster ride. Many years ago
we were told not to drink. Coaches thought that drinking during competition
would cause cramps and decrease your performance. Thank goodness that crazy

We know, we know: Stretching is confusing. One minute experts tell you to

stretching (think: touching your toes) may actually zap performance. What's
a runner to do?
Well, first, know this. You need to stretch. Running makes your legs strong,
toned, and, unfortunately, tight. Every step you take forces those quads,

As overtraining progresses, the imbalances described above worsen.
Specifically, the sympathetic part of the nervous system becomes overactive.
This results in the classic sign of an increased resting heart rate. Many
athletes become aware of this if they regularly measure their morning heart
rate, or train with a monitor. Often associated with this is restlessness
and over-excitability.

黑暗存在，应为它可以促使光明成长。
灵魂的成长需要黑暗与光明搭配。从一些古代经文和现代濒死体验的回忆录来看，最促
