Pain is different than discomfort! Muscle soreness and “feeling the burn” can occur during a normal healthy exercise routine. However, you should never experience a sharp, deep, intense, or lingering pain during or after exercise. In fact, if the soreness lasts more than 24-48 hours, than you did more damage than benefit to your muscles and other tissues and it is time to scale back and take time off. If necessary, use RICE (rest, ice compression and elevation). It is important to get in tune with your body and learn the difference between muscle strain and fatigue discomfort and pain from soft tissue damage from overuse and overload. Find the proper amount of weight and repetitions and gradually increase over time.
There is no solid evidence that stretching alone before a sport or activity prevents injury. In fact, over stretching may be counterproductive before a sport as it may weaken the muscle. The current wisdom on the matter is; never stretch a cold muscle. Instead, warm up for 5-10 minutes by actively moving the extremities and light jogging or biking and THEN lightly stretch the arms, legs, back etc. More vigorous stretching should be performed to improve the flexibility of tight muscles (ie calf and hamstring muscles) and best done after your workout but not before a sporting activity (tennis, basketball, etc.).
It depends on your body type and hormones! It is very unlikely that women and prepubescent males will bulk up from lifting weights…especially light weights (blame or thank hormones). It will, however, increase metabolism and fat burning efficiency which can lead to weight loss and good muscle tone. Stick with low resistance and high repetitions for best results.
It is not possible to target an area of the body to burn more fat! It is very common for women to ask for a specific exercise to reduce the fat in their buttocks, thighs, and abdomen. Regretfully, it is not possible to target weight loss in these areas or other body parts. In fact, when you lose weight through diet and exercise, the caloric expenditure will be evenly distributed throughout the body. However, once the adipose tissue in a specific part of the body such as the abdomen is reduced from general weight loss, targeting the area with exercises specific to that muscle group will improve the tone and definition for a leaner look in that region.
Sure, it would be great to dedicate 60 minutes 5 -6 days a week for exercise. But for most of us who work and raise a family it is not practical. The good news is that the research supports 30 minutes of exercise 3-5 days a week. Moreover, evidence shows that 10 minutes, three times a day, 5 days per week will help you attain the 150 minutes a week supported in most exercise studies.
Most people with the most common form of arthritis, osteoarthritis, feel better when they are moving. That is not to say that they don’t have increased symptoms when they OVERDO it. An exercise program specifically designed for a person’s problem and limitations will improve their symptoms and function. For example, if an individual has arthritis in their knees, they should use an exercise bike (partial weight bearing) or swim (buoyancy effect of water) instead of walk or run (full weight bearing) for aerobic exercise.
Furthermore, they would do far better with light cuff weights in a sitting or lying position to strengthen their legs than performing squats or lunges. It is important to remember, the weight gain and joint weakness and stiffness associated with a sedentary lifestyle will do more harm to an arthritic joint than a proper exercise program.
Not unless you are planning a killer workout! The number one reason most of us exercise is to lose or control body weight. High calorie sports drinks are counterproductive and unnecessary. If you do not plan on exercising for more than 60 minutes, good old fashion H2O is more than adequate. However, if you plan to do a “killer” workout for more than 60 minutes and may incorporate a high intensity interval training (HIIT) program, than a sports drink with electrolytes and other nutrients, may be of value.
For most of us, effective resistance training is not about the equipment. It is safe to say, caveman was pretty fit and strong despite the fact that he never went to a gym and lifted weights. He did however, lift, push, pull, and carry heavy stones, timber, and animals for day-to-day survival. So too, it is for modern man, the body does not distinguish between the resistance provided by a elastic band, dumbbell, or cable with pulleys and weight stacks. As long as the basic principles of strength training are applied, (isolating a muscle or muscle group, loading the muscle with enough force to bring it to fatigue without causing tissue damage, and allowing for adequate rest and recover) than the muscle will gain strength regardless of the type of resistance.
First, let me confess that I love to run and up until recently, ran almost daily. However, now that I am over 60, I had to find new forms of aerobic exercise which would be kinder and gentler to my joints. So, I mix it up between biking (indoors and outdoors, recumbent and upright), brisk walking or hiking, elliptical and stepper and swimming laps. Again, like the caveman weightlifting example, the body (heart and lungs) does not know what is causing an increase in heart rate for 30, 45 or 60 minutes, it only knows that it must respond to allow the body to function under this stress. And, in the process it becomes conditioned to the point that it will work much more efficiently when not under stress with a lower heart and respiratory rate and blood pressure at rest.
Those over 50 would be well-advised to engage in low-impact aerobics on a regular basis. For example, if you want to run two to three days per week, do not run two days in a row and consider performing low impact exercise in between. Some examples of low impact aerobics are walking, treadmill walking, swimming, elliptical trainer, and an exercise or road bike.
Change is necessary with age! For many years, I have repeatedly preached about the value of engaging in an active lifestyle throughout life. It is especially important to be active as one gets older to maintain mobility and independence. However, many take this advice to an extreme and refuse to accept the inevitable changes that occur in the body with age. They run, jump, lift and throw like a teenager and often fail to modify their activity or exercise regimen appropriately for their age. Consequently, they suffer from multiple injuries, including muscle tears, tendonitis, bursitis, impingement, and advanced osteoarthritis.
Keep in mind, everyone ages differently. One person at 60 years of age may be the equivalent of another at 50. However, change with age is inevitable, so be kind to your body…it’s the only one you have! It is always prudent to consult your physician and physical therapist for a program designed specifically for your needs.

A myth is a traditional story, idea, or belief, especially one concerning early history of a people or explaining a natural or social phenomenon. It is a widely held but false belief or idea. In medicine, health myths are also widely held beliefs about health issues such as medicines, herbs, treatments, cures, antidotes, etc. which are partially or totally false and unsubstantiated in the scientific literature. This is a partial list of the most common health myths.
You don’t need to search very long to find copious information purporting the value of water to maintain good health. Sources suggest between 8 and 15 cups of water per day! Despite the plethora of contradictory information, there is no research to support an exact amount. In fact, most scientifically validated research suggests that healthy adults do not need to count cups and those who drink water when thirsty receive adequate hydration for good health. Remember, there are many water-rich foods to provide hydration; soup, fruit, vegetables, juice, coffee, and tea. However, be aware that if your urine is dark yellow you need more hydration. And, if you are very physically active or live in a warm climate, you may require more water.
In the late 70’s, eggs received a bad reputation when high cholesterol in the blood could increase the risk of heart disease. The love-hate relationship with eggs and egg products has continued to grow since. However, recent findings suggest that eating an egg or two a day will not raise the risk of heart disease in healthy adults. While egg yolks do contain cholesterol, the amount is relatively small and is offset by the fact that eggs also have many nutrients such as omega-3’s which are associated with lowering the risk of heart disease.
Some research attempted to link the preservatives (parabens) used in some deodorants and antiperspirants with the activity of estrogen in the body’s cells because these parabens are found in breast tumors. However, there is no scientific evidence that parabens cause breast cancer. So, don’t sweat it!
Sometimes “old wives tales” are true…but not this one! Grandparents and parents have been telling their grandchildren and children to button up and don’t spend too much time in the cold. In fact, one study found that healthy men who spent several hours a day in cold temperatures (just above freezing) had an increase in virus-fighting activity in their immune systems. Moreover, it is well documented that spending too much time indoors, especially during winter flu season, puts you at risk for getting the flu…so circulate fresh air or get outdoors!
While it is commonly believed that everyone needs a multivitamin to supplement for nutrients not in your diet, research does not supported this theory. In fact, most medical experts agree that healthy adults receive all necessary nutrients and vitamins from a well-balanced diet including; fruits, vegetables, whole grains, nuts and healthy oils. However, if your physician recommends a vitamin, do so. It may be that you are insufficient or at risk due to other medical conditions. If you are pregnant, for example, you will need to take folic acid to lower the risk of birth defects.
Some diets purport that eating breakfast is necessary to stimulate your metabolism in order to lose weight. This theory is not confirmed, and for those who enjoy breakfast, it may limit hunger sensation and prevent unhealthy snacking. However, a study from Cornell University found that those who did not eat breakfast did not overeat at lunch and dinner and consumed approximately 400 fewer calories per day. So, for some healthy adults, eliminating breakfast can help lose weight…the premise of “intermittent fasting.”
Most would agree, the slimy green mucus in your tissue is disgusting. However, without a lab test, it is not a sure sign of an infection or need for antibiotics. Often, a sinus infection is associated with clear mucus and a common cold presents with green mucus.
Sugar making your kids hyper? Maybe it’s just kids being kids! It is widely accepted that sugar is not good for kids (unhealthy calories leading to obesity, etc), but, believe it or not, research shows that it is not the cause of hyperactivity (caffeine or chocolate may). It may be that parents are so focused on their behavior after sugar intake that they expect their kids to be wired when it may just be attributed to the normal behavior of kids just being kids!
Believe it or not, toilet seats are not the most unsanitary item in the bathroom. So, if you can’t cover it, don’t sweat it. Bathroom doors, door handles, and floors, however, are covered with bugs such as E. coli, norovirus, and other flu viruses. Thorough hand washing is essential and use a paper towel for door handles.
One thing is certain…cracking your knuckles is annoying to everyone around you! But studies show that it is not harmful to your joints or causes arthritis. The popping noise is not because the bones are grinding together; it is due to movement of gas bubbles in the joint capsule.
Total elimination of fat from your diet is not only unnecessary to be healthy and lose weight, but is unhealthy and harmful. Fat provides essential nutrients and is an important component of a healthy diet. Due to the fact that fats have more calories per gram than protein or carbohydrates, limiting fat intake is necessary to avoid extra calories. Instead, chose low fat dairy products (milk, yogurt, cheese) and consider eating small amounts of food with healthy fats, such as avocados, olives, or nuts.
Vaccines do not cause autism. Despite much controversy, there is no scientific evidence that supports a connection between autism and childhood vaccines. In fact, the original study that started the debate years ago has been disproven and retracted. Fact: childhood vaccines protect children from a variety of serious or potentially fatal diseases.

The New Year brings renewed energy in our collective efforts to win the race against a common foe. If we intend 2021 to be a year of joy and hope — we absolutely need to use all viable tools at our disposal and unite in our efforts to beat the coronavirus. One such tool is vaccines, considered one of the most important advances in modern medicine, and has been responsible for greatly improving our quality of life over centuries. Vaccines have allowed us to triumph over serious adverse diseases by reducing or eliminating many dangerous infectious diseases we don't even think about anymore.
Vaccination research and development has never stopped. Global partnerships have been formed to create faster, more efficient platforms and new technologies to help us against the onslaught of diseases like Ebola, Zika, and the coronavirus family — SARS (severe acute respiratory syndrome), MERS (Middle East respiratory syndrome), and now SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2).
The victory of vaccines, our most promising counter-pandemic measure, in our fight against a pathogen like SARS-CoV-2, the virus that causes Covid-19, relies on a critical mass of people becoming immune to the virus. This breaks the chain of transmission and, most importantly, protects the most vulnerable people in our community who cannot develop immunity through vaccination. This is called herd immunity — vaccines go beyond our individual benefit; it protects us as a community. Imagine this vaccinated community surrounding a pregnant mother who cannot get vaccinated now; she is protected through this invisible shield of the community blocking SARS-CoV-2 from reaching her.
Vaccine safety requirements are among the highest in the nation because they are widely distributed. Two vaccines (Pfizer/ BioNTech and Moderna) received U.S. emergency use approval (EUA) from the FDA. Nearly 2.8 million people in the U.S. have received a Covid-19 vaccine to date. Dr. Francis Collins, director of the U.S. National Institutes of Health, received the Moderna vaccine on December 22, 2020 — saying the two vaccines had been examined and put through more rigorous analysis than most vaccines to date. Nonetheless, some common myths are surrounding both vaccines:
Both approved U.S. vaccines contain no virus or viral particles. You are not injected with any part of a virus. The vaccines use synthetic messenger RNA (mRNA) that our cells can read to make a specific piece of the virus, which on its own cannot harm. This piece is the protein spikes on the outside of the virus, and it is what helps the virus dock onto a human cell and allows it to infect us. By allowing our cells to reproduce this spike temporarily, we teach our immune system what to look for in the face of a future coronavirus attack. This memory of what to look for provides us immunity and allows us to respond much faster.
The development of the current vaccines did not start in January 2020. Science has been paying close attention to the coronavirus family for many years. Research into the messenger RNA technology used in the Pfizer/ BioNTech and Moderna vaccines has been in development for close to 15 years. The perceived speed in getting the vaccines to the public is partly due to unparalleled worldwide emergency cooperation, free sharing of information, and new faster technology platforms. Also aiding has been billions in private and public funding, allowing vaccine firms to run preclinical and phase I, II, and III trials in parallel instead of sequentially. The FDA completed a meticulous safety review, and the independent Advisory Committee on Immunization panel scrutinized safety and efficacy data from the clinical trials.
Your cell's DNA is securely kept inside a nucleus in the cell. The snippet of mRNA that gets injected does not gain access to the nucleus and never comes in contact with your DNA. Your cell machinery translates the mRNA and manufactures the viral spike protein needed to present to your immune system. Once the instruction is read, human cells break down and get rid of the mRNA.
Currently, we don't have enough information to definitively know how long after infection someone might be protected from getting reinfected with Covid-19. Early indications suggest this natural immunity may not last very long. The CDC recommends getting vaccinated. However, if you are currently infected with Covid-19, the recommendation is to delay vaccination until the illness has resolved.
According to Dr. Anthony Fauci, Director of the National Institute of Allergy and Infectious Diseases, getting rid of public health measures like wearing a mask is only possible once there are extremely low levels of circulating virus left. For this to happen, we need 75-95 percent of people to have immunity to the coronavirus.
Both Pfizer/ BioNTech and Moderna have reported that their vaccines contain no preservatives. The vaccines are created using a novel methodology to synthesize the mRNA, encapsulated for protection in a lipid or oily shell. This technology allows the vaccine to be free from materials of animal origin, egg, and without preservatives. However, mRNA is fragile and can break down easily. Storing vaccines in ultracold environments keeps them stable and safe. Vaccines are thawed before injection.
Life and vaccines never present us with absolute safety in usage. We must acknowledge this — vaccines do carry some risks. Of the close to 2.8 million U.S. vaccines to date, very few recipients reported short-term mild or moderate symptoms that resolved without complication within a day or two. These included sore arms, redness at the injection site, headache, chills, fatigue, muscle pain, or fever — all expected indicators that your immune system is responding to the vaccine — and comparable to side effects seen with the shingles vaccine. As of December 23, 2020, the U.S. has seen 10 cases of anaphylaxis. Anaphylactic reactions can occur with any vaccine but are extremely rare. The cases occurred in people with a significant history of severe allergies and were safely managed with epinephrine, and the CDC has distributed safeguard protocols to vaccine sites.
But, compare these calculated vaccination risks to that of the virus itself — which has infected more than 83 million people globally and killed approximately 1.8 million — including more than 350,000 deaths in the United States. Now add in the devastation caused to economies and health systems. Dr. Walter Orenstein, the former director of the United States' National Immunization Program, wrote that if vaccines are not administered to the persons they are recommended for, there is zero impact. In the current pandemic, time is lives. We need an estimated 80 percent of people vaccinated to reach herd immunity to have a fighting chance to stop this pandemic in its tracks — and we need to get it done now.
We face a collective threat — a pandemic, and a moral dilemma on choosing to be vaccinated. Concerns over the vaccines' safety are understandable, but reports on negative outcomes are few and far outweighed by the benefits. This quarantine year has taught me that we are intrinsically bound to our community, only truly to thrive through community involvement and participation. We need each other, and we have an obligation to take care of one another. Getting a Covid-19 vaccine is not just about you; it is protecting your grandmother who has diabetes, your neighbor who is immuno-compromised — it safeguards everyone who is medically unable to receive a vaccine and needs you as their human shield against coronavirus reaching them. Vaccinations save lives — when your eligibility phase comes up, be a solid citizen, loving caring child, sibling, parent, and spouse…GET IT!
