RANKED: The world's 20 strongest militaries. Despite budget cuts and a reduction in size, the US has maintained its position as the world's strongest military, according to a report on globalization from Credit Suisse. While the US is still far and away the world's top military superpower, Russia and China are its closest rivals. Canada, however, is the weakest of the twenty countries on the list. Credit Suisse acknowledged the difficulties of determining comparative military strength in its report.
Running Form Mistake #1: Heel Striking. Heel striking is when your feet are landing in front of your hips, so your heel is hitting the ground first. Ideally, you want to land mid-foot, or on the ball of foot. Heel striking, which is fairly common among runners, can lead to injuries such as shin splints and joint pain.

A heel strike may be acceptable if the shinbone is vertical (RB â as in Bikila above), the knee is bent, and the impact loads just in front of the center of gravity. A biomechanical analysis must therefore be global.
