Exercising Outdoors: Sunblock, Sunscreen & SPF Many people prefer to exercise outdoors when possible, especially if they live in temperate climates. Those of us who live in the Midwest can hardly wait to burst out of our homes as soon as the winter gloom lifts, ready to catch sun rays at every opportunity. In either case, whether you live continuously in sun drenched climates or experience strong sunlight only 6-8 months of the year, sunscreen should be an important part of your cancer prevention treatment regimen. Keeping the Knees Strong and Supple The parts of the body are designed to take us through our lifetime (provided that we take good preventative care of them) and the knee is no exception. The knee is the largest joint of the body and can withstand loads equal to more than four times body weight. It is able to pivot, twist, bend and is self-stabilizing.
