Think twice about skipping the gym

For muscles to grow and change, the stimulus must be great enough to allow the muscles to grow back stronger than before. Muscle growth happens whenever the rate of protein synthesis is greater than the rate of muscle protein breakdown. Resistance training can profoundly stimulate muscle cell hypertrophy and, as a result, gain strength.

Just a single bout of exercise stimulates protein synthesis within 2-4 hours after a workout and may remain elevated for up to 24 hours.

There’s no exact measurement as to how much muscle you can build in a month, but it’s typically between one-half to two pounds of muscle. Overall, the timeframe generally takes several weeks or months to be apparent. Greater changes in muscle mass will happen in individuals with more muscle mass at the start of a come back. Other variables, such as volume, training intensity, genetic factors, rest, hormone levels and diet, all affect muscle gain outcomes.

Commonly our muscle mass and strength increases steadily and reaches its peak at around 30-35 years of age. After age 40, men lose as much as 3-5 percent of their muscle mass per decade. And, unfortunately, studies from the Baltimore Longitudinal Study of Aging found that muscle power declines faster after age 65 for women, and 70 for men. We really can’t “stop the clock.” So, it’s important that we push our muscles as we age. Dr. Len Kravitz, program coordinator of exercise science at the University of New Mexico, happily shares that the ravages of time on muscles have been shown to be restrained or even reversed with regular resistance training.

Of course, life and unwanted stuff happens, and it’s quite all right to take two or three weeks off. Sometimes you just need rest and recovery. Yes, your ability to generate force in the muscles does take a hit. You might notice that the 10 body-weight squats you once did with ease now have you huffing and puffing. Thanks partly to muscle memory, you can get back lost muscle quicker than you thought, reverse muscle loss, and continue to progress.

Fitness Guru- How to build muscle and lose fat at the same time

Posted on by

The best way to keep your fat cells a healthy normal size is to do a resistance training program at least three times a week.

Like it not, we’re stuck with 25-35 billion fat cells, for life. Our immune system breaks down around 10% of fat cells every year, but otherwise all our fat cells are busy expanding and shrinking in size during weight gain and loss. We need fat, as without it, we would freeze. Fat cells are also our fuel tanks, holding on to fatty molecules called lipids, and releasing them as a source of energy for the body. Fat also cushions our vital organs, stores crucial supplies of certain vitamins, and helps us have a functioning immune system. 

If you struggle with fat, turning to “gut-busting” diets and fat-burning supplements won’t “burn” fat. Fat cells don’t go away, as they are stored properly in fat cell layers under the skin. Where they are not intended to be is around organs, like the kidneys or heart, or even inside organs.

The best way to keep your fat cells a healthy normal size, and your body weight under control, is to do a resistance training program at least three times a week. Building more skeletal muscle mass and losing fat mass is one of the main reasons athletes and avid exercisers lift weights.

Within a resistance-training program, intensities, volume, and exercise selection all stimulate muscle growth. Your baseline body composition also factors in to the rate of muscle gain and fat loss.

In the first few weeks of training, newcomers to weight lifting see changes and definition in their biceps and butts. New research shows that trained individuals, not just beginners, can continue to build muscle and lose fat at the same time with two key factors: progressive resistance training and evidence-based nutrition strategies.

Mix it up

Recent studies published in the Strength & Conditioning Journal show that trained individuals can get stronger whether you train two days a week or four. In another study, there was no difference in training frequency of three times a week versus six times a week. Using a volume matched power-lifting program, both groups similarly gained a significant amount of fat-free mass and lost fat mass. It was noted that participants didn’t alter their normal nutrition habits for these particular studies.

A little more protein

Typically, to improve athletic performance it’s common practice to eat less for fat loss, and eat more to maximize muscle mass. But studies show that your post workout snack could be key to improve body composition. The authors of the resistance training studies found that approximately 70% of the subjects improved their body composition with a high-protein diet.

In one study, female collegiate volleyball players, all receiving guidance from a sports nutrition/registered dietician, added 25 grams of whey protein immediately after each power-oriented, full-body workout or a strength workout. Whether working to maximize power output, or participating in workouts specifically for strength, all athletes in each group gained muscle and lost fat. Although approaches to diet can vary with each person, the authors noted that a moderate protein intake and a more balanced nutritional approach came out at the top of the list to keep those fat cells where they need to be, no more, no less.

The magic of muscle and bone mass and brain health

Lifting weights is key to retaining lean muscle mass and keeping your weight down.

Hands down, the biggest reason people hire a personal trainer is that they want to be stronger and healthier. To achieve that goal, throughout a lifetime, it is essential that we maintain a vigorous level of physical activity to not only age well and be healthy, but also to keep our bones strong.

Lifting weights, or resistance training, is the key to retaining lean muscle mass and keeping your weight down. Around the time you turn 30, you start to lose as much as 3% to 5% of muscle mass per decade. The rate of decline of an inactive 80-year-old could be as much as 30%.

In fact, the American College of Sports Medicine and the U.S. Department of Health and Human Services recommend two or more days per week of moderate-to high-intensity resistance training, using all major muscle groups. Use it or lose is correct, as keeping your muscles strong and flexible after 30 prevents scarpenia, a condition characterized by loss of skeletal muscle mass and function. Scarpenia is a natural part of aging, but muscle loss is largely accelerated by inactivity. For many, as we get older, we tend to move less.

The ACSM’s Physical Activity & Bone Health position stand is a recommendation that adults maintain a relatively high level of weight-bearing physical activity, with no upper age limit. Activities like plyometrics—jumping jacks, for example—and high-intensity resistance training are beneficial ways to increase bone mass, as well as to preserve skeletal integrity and improving balance to prevent falls. Kids that are involved in gymnastics and sports that involve jumping, like soccer and basketball, have a great strength advantage in later life, as their bone mass is maintained into adulthood, the report notes.

The main concept of resistance training is to produce changes that result in various strength adaptations. The 80-year-old mentioned? One set of arm curls, to overload his or her biceps, can result in strength gains in the arm muscles lasting as long as a month! While my job as a trainer is to set up great programs for individuals, consider ways you can start to train, if you haven’t already, with a simple home setup, including weights, elastic bands, medicine balls, or a TRX.

Remember when?

There is good reason to stick with your routine. Physical activity is a powerful intervention to reduce anxiety and depression during a pandemic. Those of us who stayed or became active during pandemic lockdowns were less likely to experience subjective memory decline. A recent study in Preventative Medicine looked at the effect of physical activity on subjective memory decline before and during social distancing. One in three participants experienced feelings of memory decline when socially distanced, however the active participants did not.

Muscles knock back inflammation

Besides brain health, regular exercise promotes a healthy immune system. Muscles that you use doing squats, arm curls or running down a trail have an innate ability to reduce inflammation. Lately, scientists studied lab-grown engineered human muscles to examine the role of a pro-inflammatory molecule, interferon gamma, which breaks down muscle. Typically, chronic inflammatory diseases break down muscle. The lead author of the study, Zhaowei Chen, a postdoctoral researcher in biomedical engineering, found that when exercising, the muscle cells themselves are a powerful shield and can directly counter interferon gamma, the pro-inflammatory molecule, as well as protecting other tissues and cells.
