Too Much Sitting Harms the Heart, Even in Folks Who Exercise
MONDAY, Nov. 4, 2024 (HealthDay News) — There’s just something about sitting.
New research shows that too much time on sofas and chairs harms the heart — even among people who get the minimum recommended amount of daily exercise.
“Taking a quick walk after work may not be enough” to offset the health dangers of sitting, said study lead author Chandra Reynolds. She’s a professor of psychology and neuroscience at the University of Colorado in Boulder.
Her team published its findings recently in the journal PLOS One.
The data comes from an ongoing study of over a thousand former or current Coloradans, 730 of who are twins. Reynolds’ team focused on participants aged 28 to 49.
Study lead author Ryan Bruellman said the cohort was relatively young, because “young adults tend to think they are impervious to the impacts of aging. But what you do during this critical time of life matters.”
Bruellman is now a PhD candidate at the University of California, Riverside.
A lot of the participants were sitting a lot of the time: An average of almost nine hours per day, according to the study.
Exercise rates ranged from 80 and 160 minutes of moderate physical activity per week and less than 135 minutes of vigorous exercise weekly.
The Boulder team then assessed each person’s “heart age” using two key heart health indicators: total cholesterol/high-density lipoprotein and body mass index (BMI).
The result: As sitting time increased, heart aging did, too.
Even when folks met minimum daily exercise recommendations — about 20 minutes per day of “moderate” exercise — the deleterious effect to the heart of all that sitting didn’t budge.
Adding in “vigorous” exercise (for example, running or cycling) for about 30 or more minutes per day did seem to help counteract the harms from sitting, however. But it still didn’t bring those harms back to zero.
According to a news release from the university, data from the twins in the study suggests that “replacing sitting with exercise seemed to work better to improve cholesterol than simply adding exercise to a full day of sitting.”
The researchers’ suggestions for folks who sit a lot: Try using a standing desk at work, get in at least 30 minutes of vigorous exercise per day or add in strenuous workouts on your days off as a “weekend warrior.”

The overlooked key to fitness? Strengthening your joints and tendons
Isometric exercises, like planks or lunge holds, require holding a position for an extended period. In these positions, your muscles are firing, but you’re also working on the alignment of the joint and working the tendon to hold that position, says Wulke. Ho adds that while ligaments and joints cannot technically be trained directly like tendons, you can support their health by strengthening the surrounding muscles and encouraging proper movement patterns.
Wulke often programs training days with a mix of goals for her athletes: “high” days for muscle and strength development and “low” days focusing on alignment, isometric holds, and mobility. But most people don’t have enough time to dedicate separate days for joint-specific work. Instead, try integrating these movements into your existing strength training sessions. Consider adding a few sets of isometric holds during your warm-up or as a finisher.
(Is cracking your joints bad for you?)
During your workouts, focus on the eccentric phase of your movements. Slow down and maintain control throughout the exercise to help you ensure proper form. You can also use higher reps and lower weight to reduce the risk of overstressing connective tissues.
Last, Hinson recommends incorporating low-impact exercises such as walking, cycling, Pilates, water aquatics, and yoga. “Taking care of and improving the structures that make the joints stronger and more flexible—it really will pay huge dividends in keeping [people] out of my office and away from injury,” he says.

Avoid doing these gym exercises now! Orthopaedic doctor reveals exercises that do more harm; the answers may shock you
Did you know that some popular exercises that we all do at the gym to stay fit and healthy may be doing more harm than good?

The answers will surprise you.

Avoid doing these gym exercises now!
In the clip shared on The Ranveer Show Podcast Instagram page, with the caption, “Dr Venkatesh on Which Exercises you should Avoid in Gym?”, Ranveer asks Dr Movva which exercises he would recommend gymgoers to avoid as an orthopaedic doctor. He suggested three exercises which are quite popular among gymgoers aiming to get fit, lose weight or stay healthy. According to him, one should not do overhead exercises, deadlifts, and crunches.
Dr Movva stated in the clip, “Overhead, heavy [exercise]. I mean, you can go stretch, but no military press, number one. Number two crunches; avoid them. Number three, deadlifts. (sic)” To this, Ranveer replied, “So, I’d replace the military press because it’s for the anterior delts with just front raises.” As an alternative, Dr Movva suggested people to ‘bend down’ during such exercises. “You can go bend down, raise it [weights], rather than overhead (sic),” he said.
While Ranveer, a fitness enthusiast himself, said that he would replace crunches with planks, Dr Movva suggested ‘planks and bridges’.
Lastly, for why one should avoid deadlifts, an exercise you must have seen many celebrities doing at the gym and fitness influencers pushing their followers to include in their routine, the orthopaedic doctor said, “I see more injuries than benefits with the deadlifts. If you are really well-trained and have a good muscle balance, do it. But if you are trying to get better, that’s one thing you may want to avoid. Because the risk of injury is very high. There are so many other exercises that you can compensate without doing these things.”

If you are on a weight loss journey and looking for exercises to help you target these areas, worry not. We have found seven exercises to help you develop and tone your back and bicep muscles.

Back and bicep workouts to try
In the video, Meredith suggested exercises like the Smith machine or barbell mid-grip rows, outer curl into Zottman curl, cable rear delt fly, straight arm pulldowns, reverse seated rows, cable hammer curls, and cable lat pulldowns. She also demonstrated how to do each exercise in the clip and showcased modifications she added to make the routine effective.
The fitness influencer also had an inspiring message for those trying to lose weight or tone their muscles. She said, “Nobody saw my potential the way that I did…” Check out the exercises.
According to Meredith’s video, each exercise targets different areas in your back and biceps. Talking about the Smith machine or barbell mid-grip rows, she said that the exercise targets your ‘middle back for a balanced development’. For the Zottman curl, she modified the exercise by adding an outer curl, which helped her target the long head of her biceps and forearms.
While the cable rear delt fly exercise (a personal favourite of the fitness coach) targets the real delts, upper back muscles, traps and rhomboid, the straight arm pulldown helps work out the rhomboid and ‘big muscles’ on the back, thus helping create the V shape.
As per Meredith, the reverse seated rows also target the rhomboid along with the traps, biceps, rear delts, and the ‘main muscle in our backs that helps us in doing pulling movements’. Lastly, the cable hammer curls work the entire upper arms ‘focusing on the front of the arms and the outside of the forearm’, while the cable lat pulldowns target ‘lats, rhomboid, traps, and biceps’.
