  • Strength Training Can Prevent Falls

    Strength Training Can Prevent Falls

    According to a new report from the CDC, 1 in 4 Americans age 65 and older report falling each year, which accounts for the largest percentage of unintentional deaths.
     
    There were 18,000 fall-related deaths in 2007 and that rose to 30,000 in 2016. Over that span, the rate of deaths increased by an average of 3 percent annually. Moreover, there are 3 million fall-related emergency room visits annually. This is a worsening problem that needs to be addressed. 
     
    Being on multiple medicines, including blood thinners, can contribute to falling. However, reduced physical activity, plus age-related changes in gait and balance, also contribute to this problem.
     
    Balance and strengthening exercises can help prevent falls. Exercise makes your muscles stronger and more flexible, and it can also improve your balance.
     
    A comprehensive 2016 analysis by the British Journal of Sports Medicine found that exercise alone reduces the risk of falls in older adults by an average of 21 percent. What’s more, working out for more than three hours per week was linked to a 39 percent reduction in falls.
     
    As we age, our muscle mass declines. The way to thwart this is by performing resistance exercises. According to one Age and Ageing review, 1 in 3 adults age 60 and older suffer from severe muscle loss, called sarcopenia.
     
    The strength of the legs, hips and core are all critical to mobility. The loss of muscle mass and strength in the arms and upper body can also make it difficult to catch yourself if you trip and begin to fall.
     
    Focus on your body’s largest, most powerful muscle groups, such as your glutes, quads and hamstrings, while also performing single-leg and balancing exercises.
     
    A qualified personal trainer can help you perform the necessary exercises to strengthen your legs, hips, core, low back and upper body, as well as improve your coordination and mobility.
     
    Don’t wait until you (or your parents) begin falling to act. Be proactive and preventative.

  • Is Your Weight Training Intensity Adequate?

    Is Your Weight Training Intensity Adequate?

    Through many years at the gym, I’ve often seen women using the same 5-pound dumbbells for a variety of exercises: chess presses, shoulder presses, rows, bicep curls, lateral raises, front raises and more. Since weights should be thought of as tools, this is tantamount to using a screwdriver for every task, when sometimes you need a hammer or a wrench.
     
    For example, the weight you use for a chest press should be heavier than the weight you use for a shoulder press, which should he heavier than the weight you use for a lateral raise.
     
    As you work out consistently, you should grow stronger over time, necessitating the use of heavier weights for each exercise. This is especially true in the early stages of a workout program, when strength gains are most pronounced.
     
    It’s not just women either. I’ve often seen men using the same 25-pound dumbbells for an exercise that they’ve been performing for years. They make no progress because their program is not built on progression.
     
    Your body is a demand-based system. That is, the more you demand of it, the more it will produce. If you don’t steadily, but incrementally, increase the demand, your workouts and your results will stagnate.
     
    Aside from the fact that you shouldn’t be lifting the same exact weight for a variety of exercises, you shouldn’t be lifting the same exact weight for the same exercise, week after week, month after month.
     
    In short, weight training is meant to be progressive. You shouldn’t be lifting the same amount of weight today that you did one year ago. You should have gotten stronger; you should have progressed.
     
    However, sometimes your body needs a break from heavy lifting. Take it easy once a week and work on muscular endurance instead of just strength. Give your muscles a break, while still remaining active in the gym.
     
    How do you know if you are (or are not) using a high enough weight, aka, working out at the proper intensity?
     
    First, let’s define intensity, which is based on the maximum number of repetitions that can be performed with a given weight. The one-repetition maximum (1RM) is an ideal baseline:
     
    • High Intensity = 80–100% of your 1-rep max (1RM); typically 1-5 reps
    • Medium Intensity = 60–80% of your 1-rep max (1RM); 6-12 reps
    • Low Intensity = 10–40% of your 1-rep max (1RM); 15 or more reps
     
    The National Strength and Conditioning Association (NSCA) provides the following guidelines:
     
    • Hypertrophy (muscle growth) = 6-12 RM
    • Strength = 6, or fewer, RM
    • Power = 1-2 RM
     
    In order for your muscles to undergo an adaptation from training (i.e., to grow stronger or bigger), they must be stressed by working against a weight/load/stimulus that is greater than what they are accustomed.
     
    Don’t stop an exercise simply because you have reached 10 or 12 reps. Perform each exercise to the point of momentary muscular failure, whether that’s 12, 10, eight or six reps.
     
    Increasing weight means a reduction of reps. If, for example, you can chest press 40-pound dumbbells 10 times to failure, that means you shouldn’t be able to press 50-pound dumbbells 10 times (if you can, you should be working out with the 50s, not the 40s). It’s likely that you can only press the 50s six times or eight times, or whatever it might be.
     
    If the current weight you are lifting isn’t challenging, you need to increase that weight. Strength training is meant to be challenging, because the whole point is to “overload” your muscles so they become stronger.
     
    Simply put, if you can do more than 12 repetitions, you should increase the weight. Everyone could stand to be stronger. 
     
    If you determine that it’s time to increase your resistance for a particular exercise, do this by adding no more than 10 percent at a time. For example, if you’re currently lifting 50 pounds, you’d increase that by five pounds to 55 pounds. This incremental increase should keep you safe and prevent injury. It’s important to maintain good form with a new, higher weight.
     
    Remember, if you don’t make your muscles work harder than they’re accustomed, they won’t get stronger (which is the whole point). If you train progressively, your muscles will grow stronger in order to meet the increasing demands you are placing on them.
     
    Lastly, recognize that some days you will feel like the Incredible Hulk, while on other days you will feel like a mere mortal. It’s okay; it’s all part of the process. Don’t beat yourself up over a bad training day. We all have them from time to time. 
  • Why Strength Training is so Vital to Everyone

    Why Strength Training is so Vital to Everyone

    When most people think of weight training they think of big (or bigger) muscles. However, weight training is just a form of strength training, as is resistance training, which might not involve traditional “weights” at all.
     
    Resistance training can also incorporate body weight, bands, elastic tubing, medicine balls or even sandbags — anything that creates resistance. All strength or resistance training is simply a matter of overcoming gravity or tension.
     
    Strength/resistance training can benefit everyone because, muscles aside, it also increases the strength and density of tendons, ligaments and bones. Yes, strength training can prevent osteoporosis by augmenting bone mineral density.
     
    Additionally, strength training can lower blood pressure, improve cholesterol, improve athletic performance and prevent injury. There are also psychological benefits, such as better sleep, reduced stress, improved self esteem and greater confidence.
     
    However, for many people, improved appearance and body composition are the primary motivators. Simply put, muscle burns lots of calories and even body fat.
     
    Strength/resistance training helps maintain and combat the loss of muscle mass. Unfortunately, unless we perform regular strength exercises, we lose more than a half a pound of muscle every year after the age of 25. This loss of muscle results in a corresponding and significant reduction in metabolic rate, and it occurs in every decade of adulthood, which means continually less calorie burning over time.
     
    Think about that for a moment; by age 50, you will have lost at least 12 pounds of muscle, which is vital to functional movement, maintaining good posture and performing daily activities.
     
    Most adults don’t notice muscle loss. What they do notice, however, is the corresponding weight gain, which is actually fat gain. The problem for the average 50-year-old isn’t just that they’ve lost 5 pounds of muscle per decade since age 25; it’s that they’ve added three times as much body fat per decade.
     
    So, even if your eating habits don’t change as you get older, fat can still accumulate (meaning your weight increases) since metabolism usually slows with age. If you’re in your 40s, have been eating exactly the same way for 20 years and can’t understand why you’re gaining weight, it’s because your energy demand (metabolism) has dropped.
     
    Metabolism is the process by which the body uses and makes energy (calories) for everything from the digestion of food, to the cellular absorption of nutrients, to breathing, circulating blood, adjusting hormone levels, and growing and repairing cells.
     
    In the simplest terms, metabolism allows the body to process the nutrients you’ve eaten. Metabolism converts the fuel in the food we eat into the energy needed to power everything we do, from moving to thinking to growing.
     
    The number of calories your body uses to carry out these basic functions is known as your basal metabolic rate (BMR) — what you might call metabolism. Your BMR accounts for about 70 percent of the calories you burn every day. This is critically important since there is no way we can exercise away all the calories we consume each day.
     
    However, metabolism inevitably slows with age — as much as two percent a year. The key to staving off that decline is weight training. Muscle is the single most important predictor of how well you metabolize your food, how well you burn calories and how well you burn body fat.
     
    Strength training your large muscle groups at least twice a week is essential to boosting your metabolism. The effects of a good, consistent strength training program allow you to continue burning calories 24 hours a day — long after you’ve left the gym. Wouldn’t it be nice to burn extra calories while reading, driving or even sleeping?
     
    Without an appropriate training stimulus, our muscles gradually decrease in size and strength (atrophy). Untrained men and women can gain about 2-4 pounds of muscle and 40-60 percent more strength after just two months of regular strength training exercise.
     
    The notion that women shouldn’t lift heavy weights because they will “bulk up” is entirely false. Most women simply do not have the physiological ability to look like a body-builder, no matter how hard they train. That’s because women don’t have nearly as much testosterone in their bodies as men, and testosterone is a primary hormonal driver of muscle growth.
     
    Research shows that testosterone has significant effects on body fat percentage. Higher testosterone levels lead to a leaner body. Conversely, lower testosterone levels result in a fattier body. This is one reason why, generally speaking, women naturally have more body fat than men. It also means that women usually have to work harder than men to build muscle and burn fat.
     
    Muscle also helps to maintain body temperature. Ever notice that women are often colder than men in the same environment? That’s because men naturally have greater muscle composition than women and muscle generates heat (calorie burning). More muscle = more heat.
     
    For women who want to look toned, strength-training is essential, but it will only help if they lift enough weight to properly stress their muscles.
     
    Programs vary, but the American College of Sports Medicine (ACSM) recommends performing 8 to 12 repetitions of a particular strength-training exercise at a weight that completely fatigues the target muscle by the final rep. You should complete 8-10 exercises that challenge all major muscle groups.
     
    It is not necessary to train any longer than 60 minutes per workout. If you aren’t sufficiently tired by then, you aren’t working hard enough. Try increasing the load (weight), the volume (exercises, sets and reps) and/or decreasing the rest time between your sets and exercises.
     
    The ACSM also recommends training the entire body 2-3 days per week (48 hours between workouts for full body). Intermediates should aim for 3 days per week and advanced lifters should workout 4-6 days per week.
     
    If you stop exercising, muscle will not turn to fat. Muscle is muscle and fat is fat; they are entirely different body tissues. However, if you stop strength training you’ll lose muscle mass, which will make your body look less toned. You’ll also slow your metabolism, which will cause you to gain weight. That weight gain will be in the form of fat, which means you’ll likely look more flabby.
     
    In short, there are numerous valuable reasons to engage in strength/resistance training, not the least of which is to maintain your muscle mass and perhaps even gain some.
     
    Your muscles, bones, tendons, ligaments, blood pressure, cholesterol, self esteem, body composition and metabolism will all benefit from it.
