How hard should you exercise? New research to determine what’s safe and what’s not
It’s the first of its kind for B.C., and it’s going to help fill a cardiovascular research gap in Canada: a new cardiopulmonary exercise test laboratory has opened at UBC Hospital.
“The CPET machine is a core diagnostic tool that can simultaneously look at both the pulmonary and cardiac variables from a health and fitness perspective in individuals while they are exercising, such as heart rate and rhythm, and oxygen consumption,” said Dr. Saul Isserow, Medical Director of SportsCardiologyBC.
In other words, it helps determine how much exercise is safe for people of all ages and fitness abilities.
“Heart disease remains the number one killer in Canada of men and women throughout their life,” he said, adding that the research underway studies a broad spectrum of active people.
“We do see a lot of the younger athletes just to make sure they haven’t got anything they were born with that could put them at risk,” said Isserow, who is also with the Sports Cardiology Department at UBC.
He also said, that for the first time, seniors, even those in their eighties, are wanting to be more physically active than any previous generation.
“Twenty years ago, when you had a heart attack, you’re told at the most, go for a walk now and again. Now, people have a heart attack, they want to go ride the Gran Fondo, run up Cypress Mountain. So we have to study the safety of all that,” he said.
The new lab is funded through donations raised through the VGH & UBC Hospital Foundation. The lab equipment is about $100,000, but another $1 million was raised to cover ongoing operating costs.
About 1,000 people each year will be tested at the new lab. It will take about 12 months to gather initial research on how much exercise is safe.
Isserow said similar research has been done in the US and Europe, but not in Canada.
“We need our own data. We have our own unique population,” he said.
The survival rate in Canada for out-of-hospital cardiac arrests, including on the playing field, the hiking trail or in the gym, is just five per cent.
It’s hoped the work done by the lab will not only fill a research gap, but save lives.

Fitness coach says ‘just cardio isn’t enough’; shares 1 exercise women over 35 must do to stay strong and healthy
As we age, our bodies naturally start losing muscle mass and bone density, which can affect strength, metabolism, and overall health. Many women over 35 notice changes in energy levels, weight distribution, and endurance, making it essential to adopt exercises that not only tone but also strengthen the body.
Tara LaFerrara, fitness coach and personal trainer, shares in her September 22 Instagram post why women over 35 should start incorporating strength training into their routines and how it can transform both body and health.

Why does muscle loss matter after 35
If you are a woman over 35 and not doing any sort of strength training, Tara warns you’re in for a rude awakening. “I’m talking the moment that your body starts to slow down, get weaker, and feel like you hurt more,” she shares.
“It is not just ageing, it is muscle loss, and it starts way earlier than you think. After the age of 35, we start losing muscle every single year. And that muscle is so important because it is your metabolism, your bone density, your energy, and just the ability to bounce back when life throws things at you,” says Tara.
Can cardio and pilates alone keep you strong
She emphasises that cardio and Pilates alone aren’t enough. “You need to lift, squat, push, pull, and press. It’s not about getting bulky and muscular, it’s about getting strong enough to handle ageing on your own terms.”
Her advice is simple: “So if you’re tired of feeling like your body is working against you, start working with it. Pick up some weights. Your future self will thank you.”
Strength training after 35 isn’t just about aesthetics; it’s about maintaining health, mobility, and resilience. As Tara highlights, incorporating resistance exercises into your routine is one of the best ways to support your body through the natural changes that come with age.

New Year’s Fitness Resolutions Start with Healthy Sleep | Newswise
Newswise — As the New Year approaches, many Americans are setting fresh intentions to eat better and move more — and new data show those habits may deliver an unexpected bonus: better sleep. According to a new survey from the American Academy of Sleep Medicine, 59% of adults say eating a well-balanced diet helps them sleep slightly or significantly better. Staying active throughout the day may also help improve sleep. According to the survey, adults say exercising in the morning (42%) or evening (46%) helps them sleep slightly or significantly better.
“Sleep is one of three pillars of a healthy lifestyle, including eating a well-balanced diet and incorporating regular physical activity,” said AASM spokesperson Dr. Kin Yuen. “When people make New Year’s resolutions or select their ‘nudge word’ for the year, they often prioritize diet and exercise. These changes don’t just support physical health—they also improve sleep.”
The findings suggest that New Year’s resolutions don’t need to be isolated goals. Improving one aspect of health, whether diet, exercise, or sleep, can create positive ripple effects across all three areas of wellness. This is especially true for younger adults, with those 25-34 being the most likely age group to say a well-balanced diet (64%) or exercise in the evening (60%) helps them sleep better.
“Sufficient sleep significantly reduces the risk of chronic illnesses, such as obesity, heart disease, and even depression and anxiety,” said Yuen. “Whether you’re improving your diet, increasing your activity level, or managing stress, prioritizing sleep gives you the energy and mental clarity needed to start the year strong.”
Here are some tips from the AASM on how to develop healthy sleep habits and reap all the benefits of your New Year’s resolutions:
- Create a consistent bedtime routine — Make sure you are giving yourself enough time to get the recommended seven or more hours of sleep per night.
- Make time in your daily routine for physical activity — Pick physical activities that you enjoy and that match your abilities.
- Eat a well-balanced diet — Try to meet the recommended daily servings of fruits and vegetables, grains, and protein.
- Disconnect from devices at night — Turn off all electronics at least 30 minutes to an hour before your bedtime to help prepare for sleep.

About the Survey
The American Academy of Sleep Medicine commissioned an online survey of 2,007 adults in the U.S. The overall margin of error fell within +/- 2 percentage points with a confidence interval of 95 percent. Fieldwork took place between June 5-13, 2025, by Atomik Research, an independent market research agency.
About the American Academy of Sleep Medicine
Established in 1975, the AASM is a medical association that advances sleep care and enhances sleep health to improve lives. The AASM membership includes more than 9,500 physicians, scientists, and other health care professionals who help people who have sleep disorders.
