Lost your exercise mojo? Regain your motivation with these tips:

1) Think of seven fun activities you want to try - hiking, in-line skating, etc. Write them on strips of paper, then put them in a “workout jar”. Once a week, draw one out of the jar and schedule a day to try your new challenge.

2) Use the 10-minute rule. Short bouts of exercise can add up and get you motivated. Try jumping jacks in the a.m. or lifting weights while you watch TV.

3) Reward yourself. If you’ve been eyeing a new exercise top or an iPod nano, give yourself one credit for each workout. When you get to 10, hit the store!

You walk on them, stand on them and squeeze them into shoes - not to mention the heck of a beating you give them when you work out. Do these moves three times a week to stretch, strengthen and rejuvenate even seriously stressed feet.

To massage: place your fingers under the sole of your right foot. Press down wherever you feel extra tension and hold for 10 seconds. Switch sides.

To strengthen: sit on the edge of a chair; place a pencil on the floor under your right foot with the point toward your right pinkie toe. Flex your ankle, lifting everything but your heel. Fan your toes apart and drum toes one at a time over the pencil, starting with your pinkie toe. grip the pencil with your toes and pick it up, then place it back down on the floor. Repeat 5 times; switch sides.

To stretch: lie on your back with your right foot on the floor. Bend your left leg, keeping hands behind knee. Flex your left foot, slowly pointing it, reaching through your toes, then curl toes into a “fist”. Flex your ankle, then slowly uncurl toes. Repeat 5 times; switch sides.

Imagine a day when medications are custom-designed to be delivered at the right time and the right dose, based on your DNA and sophisticated diagnostic tests that will help doctors identify conditions like breast cancer and heart disease earlier - and possibly even prevent them.

These developments will be possible within the next two decades, thanks to researchers who catalogued the female X-chromosome last year and uncovered unexpected variations on how those genes behave.

These findings are expected to yield fresh insights into cancer, heart disease, autoimmune disorders and other illnesses that strike women. This means that scientists may be able to understand and predict what diseases individual women will get, what symptoms to watch out for and which treatments will be most effective.
