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.
If you increase your distance regularly and very gradually, your toes will adjust to each new maximum distance and only complain when you extend farther. In a marathon training program, almost everyone gets at least one black toenail. Running faster than you should be running, at any time during a long run, will increase the chance of this injury. Hot weather also improves your odds of getting one. When itâs warm, your feet swell more than they would on cold days.
