The Health Benefits of Strength Training

Many younger people engage in strength training for reasons of vanity rather than possible health benefits. Some people probably also believe that aerobic exercise trumps strength training when it comes to those health benefits. Well, both are important, and need to be performed regularly to receive any of the benefit we’re about to discuss. The best exercise though is the one that you end up doing most often.

How Many Days a Week Should I Be Strength Training?

The sweet spot is 2-3 sessions a week to obtain all the health benefits of strength training. One strength session a week is enough to maintain the strength that you have. An individual can experience gains in about 4 to 6 weeks if new to strength training.

What are the Health Benefits of Strength Training?

Helps Preserve Muscle Tissue. As you reach your fourth decade you experience hormonal changes that result in loss of lean muscle tissue. The loss of muscle tissue is even more pronounced after age 75. Other factors like stress and lack of sleep can disrupt the body even more. When this occurs, your body produces more cortisol, a stress hormone. The best way to offset this loss is to engage in a regular strength training program, 2-3 times a week. Strength training, if used properly, is like a magic pill. Researchers at Wake Forest University studied overweight adults who were in their 60’s. The study showed participants who lost weight and engaged in strength training lost less lean muscle mass than those who shed pounds through aerobic training.

Increases Strength. As you age, you lose strength, its that simple like taxes and death! Your strength levels peaks between 25-30 years old. Following that, it’s a downhill battle for most to hang on to that strength. Research studies have shown that strength can be reduced up to 40% by the time a person reaches age 70. By the time you hit age 75, you have about half of the muscle mass you had in your twenties.

In physically inactive people, there is a loss of about 3-5% of muscle mass per decade and a parallel decline in muscle strength, after age 30. As a result, the average person will lose 1/2 pound of muscle per year between age 30-60. This equates to about a loss of 15 pounds of muscle!

Builds Strong Bones. Strength training has been shown to increase bone mineral density. As weights are lifted, the tendons that are connected to bone, get “pulled-on” in the process. This constant pulling, over time, is what builds strong bones. This is a good thing because after age 40, you start to lose 1% of your bone density per year.

Helps Control Body Fat. A study in the journal Obesity reported that strength training helped adults become slimmer. Losing muscle reduces your metabolic rate. You feel like you’re not eating at times but still have difficulty losing weight. In turn, you see an increase in body fat. Regular bouts of strength training will preserve muscle mass and and to some extent, metabolic rate, and this with proper intake, will prevent body fat levels from rising out of control.

Hopefully, some of these statistics opened up your eyes a bit more regarding the benefits of strength training. Strength training a few times a week, is something you can do for yourself that always pays back strong dividends. Try the Functional Strength program featured on the Jefit app to help you build muscle mass. Stay Strong!

What’s a Healthy Body Fat Range?

It seems like every time we pick up a magazine or surf the web we’re overwhelmed with outlandish weight-loss claims. Let’s do a reset on this for 2020 and change the narrative. Rather than focus on weight loss like so many of us do, let’s start looking more at our percent body fat level. Do you know what your current body fat level is? You should know this number and monitor it over time.

The ideal body fat percentage for an adult varies depending on the age of the individual. Other variables that also come into play are gender, genetics, bone structure and their exercise level. College-age men typically carry 15% body fat while women have 23%, keep in mind that these numbers are for non-athletes.

Age-Related Body Fat Levels

Women:

  • 20-40 yrs old: Low fat: under 21 percent, Healthy: 21-33 percent, Overweight: 33-39 percent, Obese: Over 39 percent
  • 41-60 yrs old: Low fat: under 23 percent, Healthy: 23-35 percent, Overweight : 35-40 percent Obese: over 40 percent
  • 61-79 yrs old: Low fat: under 24 percent, Healthy: 24-36 percent, Overweight: 36-42 percent, Obese: over 42 percent

Men:

  • 20-40 yrs old: Low fat: under 8 percent, Healthy: 8-19 percent, Overweight: 19-25 percent, Obese: over 25 percent
  • 41-60 yrs old: Low fat: under 11 percent, Healthy: 11-22 percent, Overweight: 22-27 percent, Obese: over 27 percent
  • 61-79 yrs old: Low fat: under 13 percent, Healthy: 13-25 percent, Overweight: 25-30 percent, Obese: over 30 percent

Stepping onto a bathroom scale does not tell you the real story about your overall health. Your body weight is not as important as how much body fat you’re carrying. Once you can determine your body fat level, you then have a better understanding of the ratio of muscle to fat that you have.

For example, a women who weights 145 pounds and 33% body fat, can calculate that she has 48 pound of fat and 97 pounds of muscle, bone and fluid. A male, who is 205 pounds and has 25% body fat can determine he is carrying 51 pounds of fat weight and about 154 pounds of muscle, bone and fluid. Once this is known, you can start using the Jefit app to keep track of how this number changes over time. In both of these cases, the goal would be to lose fat weight while maintaining or gaining muscle, depending of course what the goals are.

Monitoring your body fat is important, and in turn, offers great insight into the status of your overall health & fitness. As you see, it’s a valuable metric to follow and offers insight into understanding if a particular strength training program is actually working.
