The ‘disgustingly small’ amount of exercise each day that slashes the risk of cancer: fitness expert

Exercising a “disgustingly small” amount per day can lower the risk of cancer, according to a fitness expert.

Nutritional scientist and professional bodybuilder Dr. Layne Norton claimed that “four minutes of vigorous activity a day” will greatly reduce an individual’s cancer risk.

“Exercise is one of the only things that you can do, independent of weight loss, that will improve all your health parameters,” Norton told host Dr. Rhonda Patrick on the FoundMyFitness podcast last week.

Citing a study published last year in JAMA Oncology, Norton said that researchers found that “vigorous physical activity” done “cumulative” throughout the day can lower the risk of cancer by 20%.

“I got in trouble because I called it a disgustingly small amount, but it really is,” the fitness expert shared.

He went on to reveal that the study found that exercising for “10 minutes” daily dropped the risk of cancer by 30%.

The study also found that just three short bursts of exercise per day can lead to a 40% reduced risk of cancer and cancer death and a 50% reduction in heart disease death. 

“If you just go walk vigorously for 30 minutes in a day you’re killing it,” the nutritional scientist said.

While some may question the findings because it was a “cohort study,” Norton quickly pointed out that “randomized control trials” have found similar indications to exercise and cancer risk.

“We have randomized control trials looking at very short bursts of exercise, seeing improvements in glucose metabolism, blood lipids, inflammation, and then now the cognitive stuff too,” Norton shared.

The fitness guru also shared that short periods of exercise have been shown to improve mental health.

He explained that the “randomized control trial” found that men with “major depressive disorder or general anxiety disorder” who did two 25-minute sessions of resistance training a week for eight weeks saw “significantly improved symptoms.”

“The effect size for major depressive disorder was 1.7,” Norton said, citing a study released last year in Psychiatry Research.

“For those who aren’t familiar with effect sizes, .2 is a small effect size, 0.5 is modest, and 0.8. Anything above 0.8 is considered large, 1.7 is massive,” Norton said.

Selective serotonin reuptake inhibitors (SSRI) — a class of drugs that are commonly prescribed to treat depression — usually fall between 0.3 to 0.8, and “the best you see is about 0.8,” he shared.

The professional bodybuilder clarified he wasn’t suggesting people should stop taking their SSRIs instead of working out but to consider other additional options to add to treatment — like exercising.

“I’m not saying we should get rid of SSRIs and have everybody exercise because sometimes maybe someone needs an SSRI just to get out of bed and actually go exercise,” Norton said. “But if we’re looking at how powerful that lever is, that’s amazing.”

However, nutritional scientists understand that getting started with routine exercise can be challenging and suggest that listeners consider it like “brushing your teeth.”

“Do you feel motivated to brush your teeth? No, you do it because you know if you don’t brush your teeth, they’re going to go to crap,” Norton said. “The same thing happens with your body if you don’t exercise.”

According to Johns Hopkins cardiologist Dr. Seth Martin, the average resting heart rate is between 60 and 100 beats per minute (BPM).

The “sweet spot” for exercise depends on a person’s age, and the target heart rate is “usually between 50 percent and 85 percent” of their maximum safe heart rate.

For a 50-year-old, it’s crucial to calculate the maximum heart rate, which can be obtained by subtracting the age from 220. In this case, it’s 170 BPM, Martin shared.

If someone aims for a 50% exertion level, their target should be 50% of that maximum, 85 BPM.

However, if a person wants to push themself to 85% of the maximum, their target should be 145 BPM.

The target heart rate that a 50-year-old should aim for during exercise is 85 to 145 BPM.

Martin noted that it’s important not to “get overly fixated on numbers” and instead just strive to exercise regularly.

Busy mum Gemma Atkinson uses this exercise to build strong shoulders fast – here’s why it’s so time efficient

Busy mum Gemma Atkinson uses this exercise to build strong shoulders fast – here’s why it’s so time efficient

Gemma Atkinson is a busy woman. When she’s not parenting her two children, six-year-old Mia and two-year old Thiago, she’s busy hosting on Hits Radio or managing her health and beauty brand Gem & Tonic. So, when it comes to working out, choosing exercises that maximise both efficiency and results is essential.

To build shoulder muscle, there’s one move she swears by: the seated shoulder press. In a video she recently posted on Instagram, she demonstrated the move and wrote: ‘Like I said, shoulders like boulders. Last set needs some F bombs to get me through. Always!’ Speaking of the importance of keeping your legs still in order to strictly isolate your shoulder muscles to prevent “cheating”, she added: ‘P.S. Elliot my PT will be screaming down the phone for me to keep my legs still.’

The seated shoulder press is a no-brainer for time-poor women looking to build muscle in minimal time as it’s a compound movement, meaning it trains several major shoulder and upper-body muscles simultaneously while allowing you to use relatively heavy loads safely with minimal setup time or effort required. In practical terms, a few challenging sets of seated shoulder presses can provide the stimulus equivalent to doing several isolation exercises separately, such as front raises and lat raises.

Personal trainer and Men’s Health UK fitness writer Kate Neudecker says that performing the move seated makes it especially effective: ‘Sitting down reduces the demand on balance, stability and bracing, so you can put more effort into the muscles you’re actually trying to train. That often means you can lift with more control, use a heavier load, and create more mechanical tension through the shoulders and triceps, which is one of the key drivers of muscle growth. There can also be a tendency to bounce at the knees to increase momentum on the standing shoulder press; the seated press eliminates this.’

She adds that it targets the ‘deltoids, especially the front and side deltoids while also working the triceps as they extend the elbows. Depending on the bench angle, the upper chest can contribute too, while the upper traps and shoulders’ stabilising muscles help control the movement.’ Here’s how to do with proper form, plus how many reps and sets to do, and how to progress.

How to do the seated shoulder press

  1. Sit, with your shoulders against the bench, chest proud, head facing forward with a dumbbell in each hand. Bend the elbows at 90 degrees with the dumbbells at ear level and palms facing forward.
  2. Now straighten your arms and press the dumbbells towards the ceiling, then return to the start. Repeat.

How to work it into your workout

Neudecker advises: ‘Always tailor reps and sets to your own abilities and needs but for muscle growth, a good starting point is 3-4 sets of 8-12 reps using a load that leaves around 1-3 reps in reserve on most sets. Evidence indicates that a large range of reps and sets contribute to muscle growth but for good technique and results, that should be sufficient. Place it early in an upper body workout if shoulder strength or size is a priority, so that you can use max muscle power.’

When it comes to progressing, Neudecker says ‘You can add weight, add reps, increase sets or improve your control and range of motion over time to contribute to progressive overload. Because balance and coordination are less of a limiting factor, it can be easier to apply progressive overload directly to the shoulders.’
