Valerie Monroe, beauty director for The Oprah Magazine, writes a monthly column -- Ask Val -- that appears on the pages of Oprah's feel-good publication. She responds to questions about make-up, skin care, hair care, and overall body care too.

In her February 2007 column, Val writes, "Many of you have written to tell me that you began to be less critical of your body when you appreciated the things it could do." As I read this, I had what Oprah would call an Aha! moment, a moment when something just clicks and makes sudden sense. Aha!, I thought, as I considered all the things my body can do, completely independent of how I look on the outside. So while I was jogging today -- my body can now easily run three miles -- I ran through all of my body's accomplishments, and I stored them in the files of my mind so I could later write them down.

Here are seven things my body can do. As you read them, consider your own body -- its strength, its power, its capacity for greatness -- and remind yourself of your wondrous self the next time you start to criticize the way you look.

• My body can partner in the creation of human life. It can carry babies and deliver them and love them and care for them and raise them. Not all bodies have this power. I am lucky.

• My body can climb an attic staircase, crawl into cramped and dark corners, pull large boxes out of wedged spaces, drag them back to the staircase, and walk backwards down the stairs with goods balancing on my head so that I can fulfill the wish my five-year-old child who wanted so badly in early November to assemble our Christmas tree and decorate our house for the holidays. "Let's wait until Daddy gets home," I told Joey when I found myself crammed into a tiny space in the attic, wrestling with a heavy box full of artificial tree parts. "You can do it, Mommy," Joey said. "You are strong." And so I fought my way through the frustrating feat because I was afraid of the lessons I would teach this little boy if I didn't. In the end, it was Joey who taught me the lesson. I can do it. I am strong.
  

• My body can endure and conquer a 5K run when it once could barely run around the block. With a little extra effort and push, I think my body can accomplish even more.

• My body, once weak and without definition, can lift increasingly heavy weight and can generate muscle tone. It can even do push-ups -- real push-ups. It takes dedication and practice and persistence and mental toughness too. But I see progress. I feel progress. And I want more.

• My body can help others. I can use my fingers to type words on a keyboard that will reach friends and family and people I don't even know. My words can inform and support and encourage and heal. I can use my hands and my semi-creative talents to create hand-made gifts, to cook and deliver very mediocre meals for friends in need, to massage my husband's sore back, to braid my niece's beautiful hair and paint her tiny nails. I can use my arms to hug my little boys with all my might. I can use my voice to communicate, my ears to listen, my senses to feel.
  

• My body can tolerate surgery and chemotherapy and radiation and horrible allergic reactions to antibiotics. My body was badly beaten by a treatment protocol intended to cure me of a disastrous disease. And somehow, in some way, it survived.
  

• My body killed cancer. With the aid of medical intervention and a hopeful attitude, my body overcame the worst and best thing that has ever happened to me. And if it could do nothing else, I would be truly happy for this one thing my body can do.
  

I am in a slump. I feel tired and slow and unmotivated. And ever since October 14 -- when I ran in the 5K Making Strides Against Breast Cancer event -- I can't seem to find the inspiration to exercise. I am making myself do it -- here and there -- but my usual drive and push and spunk are missing. Typically, I crave exercise and feel lethargic if I don't accomplish some sort of daily physical challenge. But for the past week or so, I have no craving, no desire to walk or run or lift weights, no appetite for my usual fitness routine. I am just plain tired.

Fatigue is a common side effect of cancer treatment -- even years after treatment ends, according to some experts. So perhaps my drop in energy and enthusiasm is due to the cumulative effect of my own treatment for breast cancer that just ended in June. My treatment spanned almost two years. Maybe it's no surprise my body is lagging behind my expectations for physical health.

Experts also say exercise helps combat fatigue. I believe this -- it's why I usually like exercise. It boosts my adrenaline, perks me up, makes me feel alive. If only I could get back into the swing of things, these feelings might come flooding back. But right now, I am not even thinking about how to find my old groove. I am just too tired.

I have tried to exercise most of my adult life -- at times because I felt obligated to participate in what I knew was good for me and at times to justify eating my favorite foods while maintaining an appropriate weight and at times because I wanted to actually have a toned, healthy body.

At this exact time in my life, I exercise with all of these motivations in mind -- plus a few more. I like to sweat and know I am accomplishing a physical feat. I like the mental release I get when I push my body to perform. I like the time to myself, the loud music I hear on my MP3 player, and the results I see from a little bit of hard work. And lately -- as a result of a new weight training program -- I know I am benefiting my body more than ever before.

The following are just seven of the many gifts that come from weight training. Gifts that will make me a happier, healthier cancer survivor.

Noticeable physical results -- Mostly, walking and occasional jogging have been my methods of exercise. And I've seen results from this type of workout -- leaner legs, more defined calf muscles, and the knowledge that I am increasing my cardiovascular health, as confirmed by the technician who performed an ultrasound on my heart in preparation for my Herceptin treatment for breast cancer. He told me he could tell I exercised regularly because of my low resting heart rate. But until I started weight training a few months ago, I never witnessed quick results. Yet after a few weeks of resistance exercise -- lifting 20-pound weights for my arms, shoulders, back, and chest -- I could see definition and tone that clearly would not have resulted from my purely cardio workouts.

Improved strength and endurance -- Lunges and squats and jumping with resistance bands have strengthened my legs. Lifting weights has strengthened my arms -- and I can now lift heavier weights than when I first started my new routine. I can do more push-ups now too -- not girl push-ups on my knees but real push-ups -- than I ever could have imagined doing when I could barely lower my own body weight and would crash to the floor on my stomach. My strength has improved. My endurance has improved. I feel more powerful.

Increased energy -- Fatigue (or maybe it's laziness) sometimes prevents me from happily jumping up to begin exercising. But when I push myself and exert myself and get lost in my exercise routine, my energy returns -- and not just during my workout but for some time afterwards too. Some say energy increases from strength training because it contributes to loss of fat which means we have less to lug around each day.

Burning of more calories -- Weight training raises basal metabolism which causes more calorie burning over a 24-hour period of time. Calories even burn during sleep as a result of weight training.  For every additional pound of muscle you gain, your body burns 50 extra calories every day -- 50 more calories than the few hundred that might burn from aerobic exercise. Research shows that regular resistance training can increase your Basal Metabolic Rate by 15%. So for someone who burns 2000 calories per day, that's upwards of 300 extra calories burned every single day. 

Decreased onset of illness -- Weight training can reduce the risk of adult onset diabetes and the risk for developing colon cancer and can improve the functioning of the immune system and the efficiency of the heart. It decreases the risk of low-back injuries, decreases resting blood pressure, increases good cholesterol (HDL), and improves posture. The list goes on -- and so does healthy living if weight training becomes a way of life. As a young person already having experienced a life-threatening illness, this comforts me.

Prevention of osteoporosis -- My recent bone density test revealed that I am not at this moment at risk for developing osteoporosis. I don't want this to change. Strength training can help me maintain this status because it can significantly increase bone mineral density -- which is important because we naturally lose bone density as we age. Strength training helps protect against osteoporosis. And age should not be a deterrent. Individuals who begin training late in life -- at age 65, for example -- can restore bone loss.

Improved outlook on life -- As a result of toning and shaping my body, burning calories, enjoying greater strength and energy, and working toward a disease-free future, weight training gives me an improved outlook on life. And weight training has recently been reported to significantly improve the quality of life of women recently treated for breast cancer. A May 2006 study indicates six months of twice weekly exercise was enough to improve the overall physical and emotional condition of patients.

Twice weekly is my weight training goal. I will continue to walk and run -- and bike on occasion too -- but strength training will be my priority. Because health is a priority.
