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.

Running Form Mistake #1: Heel Striking. Erik Isakson/Getty. 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.
It is usually the result of daily weight-bearing activities and exercise. The calcaneus, or heel bone, is the largest bone in the foot. It is also the first bone to make contact with the ground when walking or jogging, which makes the heel prone to stress and pain. In 30 percent of cases, heel pain affects both feet. The left heel is typically the first to be affected.
