A three-pronged approach to exercise – Harvard Health

A three-pronged approach to exercise – Harvard Health

There’s no question that getting regular exercise ranks as one of the leading strategies — if not the best one — for preventing heart disease. All forms of physical activity, even in small doses, can make a difference. But if you’re looking to optimize your cardiovascular health, a regimen that includes three types of movement may be the way to go, according to a 2024 review article in Trends in Cardiovascular Medicine.

The foundation of this exercise triad is moderate-intensity aerobic (cardio) exercise like brisk walking, one of the go-to options for meeting the federal activity guidelines (see “Exercise recommendations and examples”). Moderate activity benefits your heart by burning calories and boosting metabolism, which helps control weight. But you can reap additional benefits by adding vigorous aerobic activity (the type that really gets your heart pumping) along with muscle-strengthening exercises.

Exercise recommendations and examples

Aim for at least 150 minutes of moderate-intensity activity or at least 75 minutes of vigorous-intensity activity (or an equivalent combination of the two). Do strength training at least two days per week — even 10 to 15 minutes per session can be effective.

Your age, baseline fitness level, and health conditions all affect what workout is best for you. Ask your doctor for help creating a safe three-part workout to optimize your heart health.

Muscle-building exercise (also called strength, weight, or resistance training)

  • Weight training using dumbbells, medicine balls, kettlebells, weighted ropes, or specialized machines at home or in gyms and fitness centers
  • Exercises with resistance bands
  • Body-weight exercises (such as push-ups, sit-ups, and squats)
  • Heavy gardening or yard work (such as digging and shoveling)
  • Certain forms of yoga (such as Ashtanga, Vinyasa, and Iyengar)

How aerobic exercise helps

“People who run or do similar types of vigorous exercise may have experienced a ‘runner’s high’ either during or after their workout,” says Dr. Tim Churchill, a cardiologist at the Cardiovascular Performance Program at Harvard-affiliated Massachusetts General Hospital. That’s because your body releases feel-good chemicals known as endorphins and endocannabinoids in response to intense exercise.

Any kind of aerobic exercise, whether moderate or vigorous, also helps dampen the body’s “fight or flight” response, which plays a role in chronic stress and anxiety. Aerobic exercise also spurs the release of adrenalin and related hormones that stimulate receptors in the heart to beat more frequently and forcefully. Over time, the heart becomes more efficient, requiring less effort to send blood through the body. And as more blood circulates through the body, blood vessels expand slightly and become more flexible.

Why muscle-building matters

Including muscle-building exercises in your weekly routine has a synergistic effect with aerobic exercise that can further enhance your heart health. Strength training can make your body more efficient at burning fat for energy. It also helps improve how your body responds to insulin, the hormone responsible for regulating blood sugar levels, Dr. Churchill says. That can help prevent or improve diabetes, a potent risk factor for heart disease. Strength training also promotes the production of nitric oxide, a molecule that relaxes and widens blood vessels. “Your arteries are then better able to relax, which helps to maintain normal blood pressure,” says Dr. Churchill.

As the review article notes, combining strength with moderate-intensity and some vigorous aerobic exercise leads to greater reductions in resting heart rate, blood pressure, body weight, and body fat percentage than doing single forms of exercise. “Exercise clearly improves a lot of specific markers related to cardiovascular disease. But when you add up all those individual effects, it still only accounts for about 50% of the overall health benefit related to doing regular physical activity,” says Dr. Churchill. The elusive remaining 50% is why the decades-long quest to create “exercise in a pill” will probably never materialize, he adds.

“We naturally lose muscle mass, reaction speed and balance as we age,” says this elite Hollywood coach who’s trained everyone from Margot Robbie and Scarlet Johansson to Richard Madden and Pedro Pascal — but recommends doing step-ups to undo the damage of aging in your glutes, quads and calves

“We naturally lose muscle mass, reaction speed and balance as we age,” says this elite Hollywood coach who’s trained everyone from Margot Robbie and Scarlet Johansson to Richard Madden and Pedro Pascal — but recommends doing step-ups to undo the damage of aging in your glutes, quads and calves

There’s a reason why some of the most effective exercises tend to mirror movements in real life. It’s not because personal trainers and coaches lack imagination, but because the body doesn’t care how creative your programming is — it cares whether you can climb a flight of stairs without grabbing the banister, for example, or if you can catch yourself from a stumble.

These are just a few of the benchmarks that matter in later life, and for elite performance coach David Higgins — who has trained everyone from Margot Robbie and Scarlett Johansson to Samuel L. Jackson, David Harbour, Game of Thrones’ Richard Madden and the entire cast of The Batman, among many others — one exercise sits at the top of the list for anyone over 50: the step-up. Here’s why.

HFA Submits Comments to USTR Regarding Trade Policy – Health & Fitness Association

HFA urges targeted trade policies to protect the fitness industry.

This week, HFA submitted comments to the Office of the US Trade Representative (USTR) on two important trade policy dockets that could have significant implications for exercise equipment manufacturers, suppliers, and fitness facility operators. 

Section 301 Tariff Proceeding
USTR sought comment on proposed tariffs from its Section 301 forced labor investigation, including possible product exclusions based on domestic availability and economic impact.

HFA submitted comments that advocated excluding exercise/rehabilitation equipment and critical components, citing irreplaceable global supply chains and the industry’s role in public health, chronic disease prevention, and military readiness.

USTR proposed a new Board to identify non-sensitive products for reciprocal tariff reductions with China.

In comments submitted to USTR, HFA recommended designating exercise equipment as “non-sensitive” and eligible for negotiation, prioritizing products that boost US manufacturing and affordability, and setting criteria recognizing public health, productivity, and military readiness benefits.

The HFA thanks member operators, manufacturers, and suppliers whose data strengthened these submissions. Your efforts are helping HFA advocate for trade policy that supports the fitness industry.
