For those interested in creating a home gym or taking exercises on the road, exercise cords are a good, lightweight alternative to dumbbells. These kits often come with an anchor which allows you to attach it in a doorway for lateral or overhead exercises.
For those who travel often and find it difficult to maintain a consistent exercise program, these might be the perfect solution. They pack lightly but can give a legitimate workout when filled with water.
Chronic neck and shoulder pain is often exacerbated by people carrying too much on their backs, especially for those in metropolitan areas that need to carry their belongings throughout the day or students that are lugging around heavy text books.
The Ivar pack attempts to evenly distribute the weight of the pack, bringing items closer to your body (to decrease the torque load) and stacking the weight vertically. The larger packs have a waist strap which takes the stress off the shoulders and distributes the weight through the pelvis, which is even better. Although the best strategy to relieve pain is to lighten the load, the Ivar may be a good solution for those unable change their ways.
