3 . The holidays can be a difficult time to stay on track with your fitness goals.
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.
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.
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.
A.Plan ahead |
B.Plan out your route before you go |
C.Exercising in the morning is one of the biggest tips |
D.Remember: too much sitting is harmful to your health |
E.Your schedule will be filled with family gatherings and celebrations |
F.Get creative with exercise and make physical activity a family affair |
G.Rather than skipping the gym altogether, make time for a quick workout |

7 . 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 . 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.
