1 . The holidays can be a difficult time to stay on track with your fitness goals.     1    . Even the most disciplined people can find it difficult to stick to their fitness routines during the holiday season. Here are some expert-recommended tips that can help you stay on track.

    2    .

Planning is the best way to make sure you don’t lose track of your goals. Plan your workouts for the week and mark them in your schedule to assure they are a part of your day.

Exercise early.

    3    . Make sure workouts are in the morning and you’ll set yourself up for a productive day. Then you can enjoy holiday activities and time with family without worrying about when you’ll have time to exercise.

Keep moving.

Research shows that getting up for just five minutes every 30 to 60 minutes and performing light activities reduces the risk of heart disease risk factors. Small efforts to get moving can help your overall health during the holidays. In addition to staying active, try to avoid sitting for long periods of time, such as when watching football games or eating.     4    .

Think out of the box.

The holidays are busy, but do your best to avoid the “all or nothing” mentality when it comes to physical activity.     5     — like taking a family walk around the neighborhood before opening Christmas presents.

4 . When it comes to lowering blood pressure, studies have typically shown that aerobic (有氧的) exercises are best. Recent research suggests another type of physical activity is worth including as an effective tool to prevent and treat high blood pressure.

Exercises that engage muscles without movement, such as wall squats and planks, may be best for lowering blood pressure, according to a large study published in July, 2023 in the British Journal of Sports Medicine.

This type of training is known as isometric exercise, according to the Mayo Clinic. Isometric muscle action happens when muscles contract but do not visibly change length, and the joints involved don’t move, facilitating stability of the body. Isometric exercises can be done with weights or without, just relying on the body’s own weight.

“These findings provide a comprehensive data-driven framework to support the development of new exercise guideline recommendations for the prevention and treatment of high blood pressure,” said study coauthor Dr. Jamie O’Driscoll in a news release.

The researchers looked into randomized controlled trials that had reported the effects of exercise interventions, lasting two or more weeks, on blood pressure between 1990 and February 2023. From a review of 270 trials with 15,827 participants, the researchers found that among HIIT (high intensity interval training), isometric exercise, aerobic exercise, dynamic resistance training and a combination of the latter two, isometric exercise led to the greatest reductions in blood pressure.

It’s also important to note that there are other lifestyle changes as well as exercise that can benefit your blood pressure. These include keeping to a healthy weight, eating a balanced diet, cutting down on salt, not drinking too much alcohol and ensuring that you continue to take any prescribed medication.

More research is needed to determine exactly why isometric exercises might be better for lowering blood pressure than other types of training, the authors said.

5 . Tai chi, a traditional, slow-moving form of Chinese martial art, is known to increase flexibility and improve balance. Now, new research suggests it’s better than more energetic aerobic exercises (有氧运动) for lowering blood pressure in people with prehypertension (高血压前期). Prehypertension is considered a warning sign that heart disease may be ahead, and it raises the risk of having a heart attack.

The new findings, published in the journal JAMA Network Open, add to a large body of research pointing to health benefits from tai chi.

In the study, researchers in China randomly assigned 342 adults with prehypertension to one of two interventions. The average age of participants was 49. Roughly half the people participated in aerobic exercises, including jogging, climbing stairs, brisk walking and cycling. The other half was trained to practice tai chi. Both groups got hour-long sessions four times a week.

After 12 months, those in the tai chi group saw bigger drops in their blood pressure than those in the aerobic exercise group. What’s more, nearly 22% of the people who practiced tai chi saw their blood pressure fall to within normal range, compared with nearly 16% of people in the aerobic exercise group. And fewer patients in the tai chi group went on to develop hypertension than in the aerobic exercise group.

How does tai chi help lower blood pressure? The practice tends to cause more of a response from the parasympathetic nervous system (副交感神经系统), says Ruth Taylor-Piliae, a professor at the University of Arizona’s College of Nursing, who was not involved in the study. The parasympathetic nervous system is the network of nerves that relaxes your body after periods of stress or danger.

“I think the beauty of tai chi is that you don’t have to have a special gym membership or special clothing,” Taylor-Piliae says. “Once you learn tai chi, you can do it anytime, anyplace, anywhere. And it does kind of provide that calming, relaxing effect.”

9 . Despite what most people might think, you really don’t need much time to work out. In fact, even ten to twenty minutes of challenging exercise a few times a week is enough to burn fat, build muscle, boost strength, and contribute to a healthy, active lifestyle.     1    

But sometimes, the resistance isn’t really about the actual time the workout takes. It’s about the energy it takes to get ready for it. Maybe your stress levels are over the top, or your energy levels have been so low that you keep talking yourself out of a workout. Or maybe you just don’t want to get all sweaty and have to take a shower afterward.     2     In such fast-paced life, we’re all struggling. But when it comes to exercise, being healthy and fit isn’t as black and white as the fitness world tries to make it seem.     3     Doing something is always better than nothing when it comes to movement. Micro workouts, like getting out for a fifteen-minute walk instead of doing the strength training workout, are significantly better than doing nothing at all.

    4     They are time-saving, since they can be done in seconds or in as little time as 15-20 minutes. They require minimum space and equipment. Many can be done at home, in the park, or even while waiting in the checkout line. They are also money-saving as these can be done without a gym membership, coach, trainer, or class instructor.

So in order to maintain a healthy lifestyle, make time to move.     5     If all the movements like push-ups and pull-ups add up, you will still get many of the same benefits of a longer, harder workout.

10 . Today, many people are turning to social media for their fitness routines, with TikTok, one of the most popular platforms. Indeed, its fitness category has some 300 billion views. But are the posted works, exercises and challenges really safe and effective?

While fitness influencers can encourage people to become more physically active, which is a positive, the quality and accuracy of their content is a concern, according to a 2023 review in Frontiers in Public Health.

“There are a lot of unsustainable and unrealistic workouts on TikTok, and even some dangerous advice,” said Jess Brown, a certified personal trainer in Westchester, New York. “What’s more, much of the fitness information on TikTok isn’t backed by science or posted by fitness professionals. The workouts are usually generalized to anyone, too, and don’t take into account your health, your family history, your flexibility, your range of motion—the list goes on,” said Monica Jones, a certified personal trainer in Washington, DC.

One of the more popular TikTok fitness trends involves developing your abdominal muscles. These challenges often show an influencer doing one exercise or series of movements that, if repeated daily for a week or two, is promised to result in a sexy six-pack. “No way,” Brown said. “We’ve proven again and again that spot reduction isn’t a thing.”

“Unfortunately, there will always be trends centered around getting fast results, because those grab people’s attention. But it’s important to look at your fitness and health as a lifelong journey, not something you can achieve within 10 to 90 days,” Jones said.

How can you separate quality workouts from dangerous ones? First, check the information of the posters. They should be certified fitness professionals who have experience working with people. You also want a coach who emphasizes improving strength and health, not one who focuses on body type. A quality influencer should encourage mental well-being, self-care and the importance of listening to your body in addition to physical fitness.
