Swim to stay healthy

Swimming is not only one of the best total-body exercise forms, it can also help you avoid getting sick. Take the plunge!

Swimming is an excellent way to reduce the risk of disease. It works your entire body and activates all the major muscle groups; contributes to muscle strength, flexibility, posture, and endurance; promotes weight loss and stress reduction; and improves cardiovascular conditioning by lowering your resting heart and respiratory rates and making blood flow to the heart and lungs more efficient. Swimming is also very low risk for injury because it places stress on your bones, joints, and connective tissues, thanks to the buoyancy of the water. Swimming 15 to 30 minutes each day can have a very positive effect on your overall health.

Survival tips for couples during the holidays #3: Repair

When tensions arise between you and a loved one or friend, here are some tips to help you defuse and repair the situation.

When having a disagreement with your spouse or partner, defusing the situation helps calm things down and helps you and the other person reconnect and repair your relationship. You can defuse most situations by:

  • agreeing to disagree;
  • bringing humor into the conversation;
  • using gentle statements; or
  • being intimate.

Sometimes what works in one conflict doesn’t work in another. Be flexible and see what works—make the effort to use one or more of these techniques in every disagreement.

Be specific about your training

You will get the best results from your training program if you tailor it to fit your personal goals and activities.

When training, an athlete should be specific about methods of training that meet the needs of the activity he or she is training for. To achieve an optimal performance level, a sprinter will train in a different way than, for example, an endurance athlete such as a marathon runner. Make sure that you “stress the physiological systems” right for your type of activity. In other words, if you are going to compete in a race, you need to run to become a better runner. Likewise, if you are going to compete in a cycling or swimming event, you must perform those exercises to become better. Wanna be a better tennis player?  Play tennis! Although a well rounded program that includes strength training, aerobic conditioning, and flexibility exercises will improve your general fitness, to improve at a specific activity or sport you must perform that particular exercise.

Survival tips for couples during the holidays #2: The Four Horsemen of the Apocalypse

The “Four Horsemen of the Apocalypse” are characteristics that when present in communicating can destroy relationship satisfaction over time.

Last week we started a series on survival tips for couples during the holiday season and discussed how many positive interactions couples need to do to make up for one negative interaction. This week, we're focusing on the “Four Horsemen of the Apocalypse”—a term coined by researchers for four features of communication that can destroy a relationship over time. Try to avoid these when communicating with your loved one:

  • Criticism: Don’t made global negative statements about each other.
  • Contempt: Don’t be sarcastic (in a mean way) or mocking towards your loved one.
  • Defensiveness: Don’t respond to defend your behavior without first listening.
  • Stonewalling: Don’t withdraw or ignore your loved one.

Too much of these characteristics has been linked to unhappy relationships over the long term. As stress and tensions rise throughout this holiday season, remember to be vigilant about avoiding these four kinds of behavior.

Marines address boot camp injuries

Reducing injuries during boot camp is a priority for the Marine Corps; athletic trainers keep watch over recruits to ensure the 13-week training is as injury-free as possible.

The Los Angeles Times is reporting on how the Marine Corps has hired 27 certified athletic trainers—most with experience tending professional and college athletes—to oversee training for enlisted recruits and officer candidates at sites throughout the United States. According to the article, this is a new direction for the Corps: Not that long ago, the drill instructors might have dismissed recruits who complained of being injured and ordered them back into action.

Survival tips for couples during the holidays #1: Positive versus negative

Learn how many positive behaviors you need to make up for one negative behavior in your relationship with your partner.

The holidays can sometimes be a difficult time for relationships. Through this holiday season, remember to compliment your loved ones and show them on a daily basis that you care for them. are thinking of them, and love them. Couples who do five positive actions for every negative one are more likely to have long, happy, successful marriages. Contrastingly, unhappy couples are more likely to have one positive interaction—or even less—for every negative interaction.

Progressive overload injuries

Don’t get injured by trying to do too much too soon. Ramp up your exercise regimen slowly and steadily to avoid getting hurt—and having to start over.

Overuse injuries are a common risk associated with the rigors of physical training. A healthy tip to implement into your training program is to gradually increase your training workload by just 10% each week. This will help—but not guarantee—to reduce the risk of muscle or joint injury such as tendonitis or stress fractures caused by repetitive trauma. In essence, keep the progressive changes in your activity levels gradual, listen to your body, and make incremental adjustments in time and intensity until you reach your new fitness goals.

Pick the battles you both can win

The majority of problems among couples actually are not solvable, but they can be dealt with through discussion.

Research on couples relationships over time has found that around 70% of problems among couples remain the same throughout the relationship, which means that only about 30% of problems can be resolved. Therefore, learning how to work on the problems that can be resolved and engaging in an ongoing discussion around perpetual problems is the key to happy long-term relationships. Recognizing that the perpetual problems are not going to be directly overcome can help couples be less frustrated at their partner for issues that just cannot be resolved. Therefore, learning to live with the perpetual problem, and talking to your loved one about it as needed, can help ease couples relationships in the long run.
