Everyone likes a bargain, and lap swimming is a good deal when it comes to exercise. Swimming is a remarkably effective workout because it combines three important types of exercise in one: aerobics, stretching, and strengthening. “Simply keeping yourself afloat activates the core muscles in your back and abdomen. And you have to move all of your muscles to swim,” says Leigh de Chaves, a physical therapist and clinical supervisor of rehabilitation services at Harvard-affiliated Brigham and Women’s Hospital. (She also swam competitively in college.)

Are you a good candidate for lap swimming?

Consider lap swimming if you’re generally healthy, you’re a good swimmer, and your doctor says it’s okay. It’s no problem if you’re not a fan of the crawl: “Any stroke is fine. The breast, side, and back strokes are often favored because a lot of people don’t like putting their face in the water, like you have to do with the crawl,” de Chaves says.

However, lap swimming might be not be doable if you have an underlying condition, such as heart disease or a seizure disorder, that puts you at risk for a life-threatening event in the water. You may also need to skip lap swimming if you’re not strong enough to climb in and out of the pool easily. And you should be careful if you have injuries to your shoulders or neck. Lap swimming may increase your pain.

Start your lap swimming routine slowly

A green light for a lap swimming routine doesn’t mean you should start with 20 laps. Ease into it. “Focus on the amount of time you spend swimming, at first. For example, swim for five or 10 minutes, a few times per week. Gradually increase the amount of time each week, and note how many laps you can do within that time. Eventually, set goals to increase your speed by doing more laps in your set time, so that you can measure your progress,” de Chaves explains.

A big payoff

Once you’re in the swim of things, you’ll notice lots of benefits to lap swimming. It’s easy on the joints, thanks to buoyancy in water, and it has a meditative quality that forces you to focus on your movement and breathing.

Lap swimming also

  • improves endurance and cardiovascular health
  • helps lower blood pressure
  • increases flexibility
  • helps you control your weight
  • boosts your balance
  • reduces fall risk
  • helps sharpen thinking
  • helps reduce stress.

Some dos and don’ts for lap swimming

De Chaves points out that it’s important to warm up your muscles before diving into a lap swimming workout. All it takes is a few minutes of gentle paddling, and then static stretches of your shoulder and leg muscles.

Some other dos and don’ts:

  • Do wear nonslip shoes or sandals when walking on the pool deck.
  • Don’t forget to apply sunscreen if you’re swimming outdoors.
  • Don’t forget to stay hydrated before and after a workout.
  • Don’t skip stretching your muscles after lap swimming. You’ll want to stay flexible so you can get back in the pool.

For the nonswimmers in the pool

If you’re not a lap swimmer, you can still benefit from aquatic exercises — exercising in the shallow end of a pool. You might take a class with a trainer who leads a group through a set of exercises with special water weights or flotation devices (like a pool noodle). Or you can simply try water walking; working against the resistance of the water is good for your muscles and bones.

“If you have balance problems, it’s a good idea to exercise with a friend who can assist you. I also recommend wearing a buoyancy belt around your waist to keep you upright,” de Chaves advises.

Look for aquatic exercise classes — such as strengthening or aerobics — at the local YMCA, a fitness center, or a community center.

Muscles in your body are a use-or-lose proposition. You need to use them to keep them strong!@ClevelandClinic – Susan Williams, MD. endocrinologist

Muscles in your body are a use-or-lose proposition. You need to use them to keep them strong!

You may not realize it, but we all start losing 1 percent of muscle mass each year after age 30. That’s why your diet in later years should not look the same as it did when you were younger, says endocrinologist Susan Williams, MD.

Skipping breakfast, eating fast food and being inactive in your 20s and early 30s might not hurt your health in the short term. However, poor nutrition and lifestyle habits take their toll over time.

People who embrace good habits early on really get ahead of the game, Dr. Williams says. But it’s never too late to start eating better and taking better care of your body.

Whether you’re 30 or 50, Dr. Williams offers three important tips to get started in eating right when you are thinking about your long-term health.

1. Keep your weight in check

A roller coaster of weight gain and loss can change your body composition and leave you with more fat mass and less lean muscle mass.

2. Eat three balanced meals a day

You also want to limit your snacks in between. The word “balanced” is especially important because eating a wide variety of foods will help you prevent nutritional deficiencies.

Dr. Williams suggests this simple shopping list:

  • Lean proteins. Choose chicken, white fish, oily fish like salmon, eggs, tuna fish and red meat (less frequently than other protein).
  • Whole grains. This includes multigrain breads, and long-cooking rice or oats.
  • Veggies. Go for fresh or fresh frozen. Choose what’s in season and enjoy a variety to get the vitamins and minerals your body needs.
  • Fruit. Fresh fruit is best, followed by frozen. Canned fruit can be OK, but choose options in light syrup or water. Check the label and avoid added sugar.
  • Dairy. Choose milk, yogurts, cheeses and cottage cheese that are low-fat or fat-free.

Steer clear of cookies, cakes, pies, ice creams, juices and rich desserts. If that sounds like no fun, Dr. Williams advises treating these foods as treats. Save them for dining out or special occasions, but don’t make them part of your daily diet.

3. Use your muscles

Eating protein and being physically active are equal partners in the quest for maximum health, Dr. Williams says. Muscles are made of protein, but simply eating protein is not enough to save them.

“Muscles in your body are a use-or-lose proposition,” she says. “You need to use them to keep them strong.”

Can’t carve out time for the gym? Try this daily routine:

  1. In the morning, stretch for 10 minutes.
  2. At lunch, eat and then walk for 10 minutes.
  3. After dinner, spend 10 minutes with stretch bands or light weights.

Even a half hour of physical activity can make a world of difference, especially if you make it a habit in your 30s. “Don’t let your weight creep up while your muscle mass creeps down over your 30s and 40s,” Dr. Williams says. The longer you wait, the harder it will be to get started — and the more muscle you will have already lost.
