Whether you’re training for your first 5K or looking to smash a marathon PR, fartlek could be the game-changing workout your running routine is missing. Fartlek is Swedish for “speed play,” this unique running method blends freedom with structure, play with performance, and science with simplicity and it might just be your secret weapon for endurance, speed, and improved cardiovascular health.

Fartlek training was invented during the 1930s by Swedish Olympic trainer Gösta Holmér, who was looking for a method to make his athletes faster and more resilient without the tedium of repetitive exercise. In contrast to regular interval training, in which recovery periods are specifically set, fartlek promotes ongoing movement with changing intensity alternating sprints of speed with slow recovery runs, all without stopping.

This "playful" approach not only wards off boredom but also provides a smooth transition between base running and more formal speed work. It's a method that encourages spontaneity while enjoying serious physiological rewards.

What Exactly Is a Fartlek Run?

Fundamentally, fartlek is a type of unstructured speedwork. In a fartlek session, you vary between harder and easier running, but in contrast to intervals, there are no full rest pauses. You may sprint for one minute, jog for three, run hard to the next tree, then recover until the next lamppost.

You can create your own rules based on either time or distance. For instance:

• 1 minute fast, 3 minutes easy
• Half a mile fast, half a mile recovery jog

Why Fartlek Training Works?

Fartlek is not merely a curiosity of bygone days. It's grounded in exercise physiology that makes sense of its utility for building cardiovascular endurance, lactate threshold, and muscular economy. Since the "recovery" periods are still working hard, your heart rate stays high, putting extra stress on your aerobic system — which is a potent tool in the hands of long-distance runners and recreational joggers alike.

Further, pace variation also enhances the ability of your body to recycle lactate, with an overall energy expenditure. Fartlek training serves to condition your body to excel in conditions experienced in real races, where the pace can constantly change with the terrain, competitors, or wear and tear.

For novices or runners coming back from a break, fartlek provides an easy point of entry to increased-intensity work. With no stopwatch or track required, it eliminates intimidation and lets you tap into your perceived effort. You're not tied to strict measures — you just run by sense.

That flexibility is also what makes fartlek perfect for use in initial stages of a training cycle. It gets the mind and body ready for more organized sessions in advance, without burning them out.

Fartlek vs. Other Speed Workouts

Let's discuss how fartlek is different from tempo runs and interval training:

Tempo runs: Consistent runs at a "comfortably hard" rate — usually around 20–45 seconds slower per mile than your 5K pace. They develop lactate threshold but lack the same variability as fartlek.

Intervals: High-intensity efforts with full recovery or slow recovery (e.g., 8 x 400m with full recovery). They're more structured and performance-oriented than fartlek.

Fartlek: Balances speed and endurance without full rest. Less predictable, more flexible — and sometimes more fun.

Why You Need to Add Fartlek into Your Training?

1. It Mirrors Race-Day Reality

Races are not run at a set pace with prearranged recovery periods as with intervals. Fartlek simulates the unpredictable nature of racing — surges, hills, and tactical fluctuations — making you more resilient.

2. It Educates Self-Regulation

By allowing you to control when to accelerate and decelerate, fartlek training develops body awareness. You'll discover how to monitor effort, deal with fatigue, and adjust pace — essential skills for any distance runner.

3. It's Efficient and Convenient

With hectic lifestyles, sometimes all you can manage is 20–30 minutes. A short fartlek session over lunch or on a nearby trail can bring significant payback in a concise manner.

4. It Keeps Things Fun

Running doesn't have to be all about numbers. Fartlek brings some spontaneity into your routine. Skip the GPS watch, select a scenic route, and let your instincts dictate your pace.

Key Fartlek Workouts to Try

1. Free-Form Fartlek

Select a natural route and perform 10–25 short bursts (15 seconds to 4 minutes) with steady running in between. Use landmarks as your navigation.

2. Bridging Fartlek

Perfect early in a training plan: attempt 10 reps of 30 seconds hard, 90 seconds steady — building over time to 1-minute hard, 1-minute steady.

3. Mixed Paces

Develop endurance with decreasing intervals: 6, 5, 4, 3, 2, 1 minutes — increasing the pace as you go, with 90 seconds of slow running in between attempts.

5. Marathon Prep Fartlek

Alternate 3 minutes slower than marathon pace with 3 minutes faster for 60 minutes of a longer 75–90-minute run.

Fartlek training may not receive the same banner headlines as high-tech interval training or boutique studio classes, but its very simplicity is its genius. Supported by decades of practice and current science, this vintage approach continues to pay dividends in stamina, speed, and aerobic fitness while keeping running interesting and enjoyable.

Just one bout of physical activity, specifically resistance training or high-intensity interval training (HIIT) may trigger a measurable anti-cancer response in the body. That’s not wishful thinking. It’s the takeaway from a compelling new study by researchers at Edith Cowan University (ECU) in Australia, who found that a single workout could slow the growth of cancer cells by as much as 30%.

While exercise has long been considered a complementary therapy in cancer care, this study sharpens the focus. It suggests that even short-term, intentional movement could offer physiological benefits for breast cancer survivors at the cellular level. And that’s a big deal.

Led by PhD researcher Francesco Bettariga, the ECU study explored how exercise impacts breast cancer survivors not just in the long term, but immediately. The team zeroed in on myokines, which are proteins secreted by muscles during exercise. Myokines are emerging as powerful players in the body’s defense system, with proven anti-inflammatory and anti-cancer effects.

Participants in the study—all breast cancer survivors underwent either a single session of resistance training or HIIT. Researchers then measured their blood before, immediately after, and 30 minutes post-exercise. The results showed a clear and consistent increase in myokine levels across both workout formats.

This spike wasn’t just theoretical. Bettariga’s lab data indicated that these boosted myokine levels could reduce the rate of cancer cell growth by 20–30%, after just one session.

Why It Is More Important for Breast Cancer Survivors?

We already know that cancer—and the treatments used to fight it—can wreak havoc on the body’s immune system and metabolism. Fatigue, inflammation, muscle loss, and long-term damage to cellular function are all common side effects. That’s part of what makes this study so significant: it demonstrates that even bodies under considerable strain from cancer treatment can still mount a biological defense through exercise.

“The results from the study show that both types of exercise really work to produce these anti-cancer myokines in breast cancer survivors,” Bettariga noted. “The implications are powerful—this is strong motivation to integrate exercise into cancer care.”

What’s unique here is the immediacy. Most studies emphasize the long-term benefits of exercise over weeks or months. This one highlights a biochemical response that kicks in within minutes.

Link Between Inflammation And Body Composition?

Beyond myokines, the study also looked into another critical component of cancer recurrence: inflammation.

Persistent inflammation plays a major role in tumor progression. It promotes the survival and spread of cancer cells and suppresses the immune response, making it harder for the body to fight back. Worse, both cancer and its treatments can increase inflammatory biomarkers in the bloodstream.

According to Bettariga’s extended research, the answer lies in body composition—specifically, reducing fat mass and increasing lean muscle through consistent exercise.

“Strategies are needed to reduce inflammation,” he said, “which may provide a less supportive environment for cancer progression, leading to a lower risk of recurrence and mortality in survivors of breast cancer.”

Building lean muscle through resistance or interval training doesn’t just make you stronger. It could actually help change the biochemical environment of your body to be less hospitable to cancer cells.

Why Diet Alone Isn’t Enough?

The study also underscores an important caveat: quick-fix weight loss strategies don’t deliver the same benefits. In fact, losing weight without preserving or building muscle may do more harm than good.

“You never want to reduce your weight without exercising,” Bettariga cautioned. “You need to build or preserve muscle mass and produce these beneficial chemicals—like myokines—that you can’t get through diet alone.”

That means crash diets, juice cleanses, or calorie-cutting without movement won’t contribute meaningfully to the anti-inflammatory or anti-cancer response. The muscle is the medicine in this case—and it has to be activated.

How to Add HIIT or Resistance Training into Your Routine?

If this all sounds powerful but overwhelming, start simple. The study wasn’t testing elite athletes. It was studying real breast cancer survivors, many of whom were new to structured exercise routines. For resistance training: Think compound movements that target large muscle groups—like squats, lunges, push-ups, or lifting light weights. You don’t need a gym or equipment to start. Even bodyweight training done consistently can build lean mass.

For HIIT, try alternating 30 seconds of high-effort movement (like jumping jacks, stair climbs, or brisk uphill walking) with 1–2 minutes of slower recovery. Repeat the cycle for 15–20 minutes.

The key isn’t the duration, it’s the intensity and consistency. According to Bettariga’s findings, even one session is enough to jumpstart the body’s internal defense mechanisms.

Can This Improve Future of Cancer Care?

There’s a growing shift in how we view recovery and survivorship. No longer is exercise considered a “bonus” or “optional.” Increasingly, it’s being recognized as a core component of medical care—one that can potentially alter the trajectory of disease, especially in cancers with high recurrence rates like breast cancer.

While more research is needed to explore the long-term implications of myokine production and its effect on cancer recurrence, the current data is promising. At a time when many cancer survivors are looking for ways to reclaim control over their bodies, this study offers something rare: a simple, immediate action that can make a real difference.

It is very easy to do exercises wrong, especially strength exercises. The reason why one must be careful when they are doing weights is because you could end up overexerting one certain muscle and not get the results you wanted. One such exercise is dumbbell row.

Sitting at a desk all day or focusing on "pushing" exercises like bench presses can lead to rounded shoulders and back pain. Dumbbell rows are a "pulling" exercise that helps balance your body. They strengthen your back muscles, which can improve your posture and reduce common aches and pains from daily life.

How to Do a Dumbbell Row

Dumbbell rows are a simple yet effective exercise. Here's a step-by-step guide to doing them correctly:

1. Place a workout bench in front of you. Stand with your feet about shoulder-width apart.
2. Steady yourself by putting your right hand on the bench. Pick up a dumbbell with your left hand.
3. Keep your back straight, creating a diagonal line from your head to your hips. Your shoulders should be slightly higher than your hips.
4. Keeping your left arm close to your body, pull the dumbbell straight up toward the ceiling. Your spine should stay completely still—only your arm and shoulder should move.
5. Slowly and with control, lower your arm back down to the starting position.

Tips for Perfect Form

Even though dumbbell rows seem easy, paying close attention to the details will help you get the best results and avoid injury. To prevent straining your neck, keep your head still and look at a spot on the floor about three feet in front of you. It’s also a good idea to start with your weaker arm first so you can give it your full attention when you have the most energy.

Focus on your breathing. Inhale before you pull the weight up, then breathe out as you pull. Or, you can hold your breath as you pull and breathe out at the top or on the way down. This helps keep your core stable. When choosing a weight, start with a lighter one and work your way up. The last repetition should be difficult, but not so heavy that you have to swing your whole body to lift it. You can also slightly change the angle of your elbow to target different back muscles.

Muscles Worked by Dumbbell Rows

Dumbbell rows are great for building strength in your mid and upper back. This exercise targets several important muscles, including your lats which is the large muscles that keep your back stable and help your shoulders move, your traps which are the muscles in your neck and upper back that help move your head and maintain good posture, and your rhomboids, the upper back muscles that help stabilize your shoulders.

Back pain is one of the most common reasons people see a doctor. By adding dumbbell rows to your workout, you can strengthen the muscles in your back and build better posture. This can lead to less back pain, a stronger core, and an improved range of motion.

Dumbbell rows can be a fantastic part of your fitness routine. However, if you have any health concerns, recent injuries, or long-term medical conditions, it's always a good idea to talk to a doctor or physical therapist before you start a new exercise.

Lifestyle changes are necessary at every age. Young adults often get away with eating unhealthily, staying up late and getting up early. However, as you grow older, the effects of staying up beyond a certain time, indulging in alcohol or even overexerting yourself become apparent. So one must make changes to their lifestyle according to their age. As such, people above 60 should pay more attention to certain aspects of their health like their brain health, as they are susceptible to cognitive decline.

A new study shows that a two-year program focused on healthy eating, exercise, and "brain training" helped older adults avoid a decline in their thinking skills. The study, called U.S. POINTER, included more than 2,100 people aged 60 to 79 who had a higher risk for cognitive decline due to factors like a poor diet, a sedentary lifestyle, and a family history of memory problems. The results were presented at the Alzheimer’s Association International Conference in Toronto.

Combination of Healthy Habits

The participants in the study followed a program that focused on three key areas:

Healthy Eating

Participants switched to the MIND diet, a specific eating plan known for supporting brain health. This change from their previous unhealthy diets was a key part of the program to boost cognitive function.

Regular Exercise

The program required participants to meet fitness goals that included a mix of exercises. They did aerobic workouts, resistance training, and stretching to improve both their physical and mental health.

Brain Training

Participants were also tasked with exercising their minds. They used a program called BrainHQ for daily challenges and engaged in other intellectual and social activities to keep their brains active and sharp.

Participants in a more structured version of the program met regularly with staff and peers, while a second group followed a less structured, self-guided plan. The results showed that the structured program provided a greater benefit to brain health. An impressive 89% of all participants completed the two-year study.

Broad Benefits for a Diverse Group

The study found that this program worked well for a wide range of people. It didn't matter if they were male or female, what their ethnicity was, what their genetic risk for Alzheimer's was, or what their heart health was like. Everyone seemed to benefit. The researchers saw a significant improvement in the participants' overall thinking skills, including their memory, attention, and ability to multitask. This research sends a strong message that making healthy choices can have a powerful impact on brain health for many people, and it shows that treatments for diseases like Alzheimer's will likely include both medicine and healthy living.

Physical Activity Guideline For Elderly

According to the UK National Health Services older adults should try to be physically active every day. Regular activity can help improve your overall health and lower your risk of serious conditions like heart disease and stroke. Before starting any new exercise routine, especially if you haven't been active in a while or have health concerns, it's a good idea to talk to a doctor. They can help you choose activities that are safe and right for your fitness level. Here are some goals for them

• Be active daily, this can include light activities like walking.
• Do exercises that improve your strength, balance, and flexibility at least two days a week. This is especially important if you are worried about falling.
• Get moderate exercise, aim for a total of 150 minutes of moderate activity per week. This could be a brisk walk, dancing, or gardening.
• Get vigorous exercise, aim for 75 minutes of vigorous activity per week. This could be jogging or a strenuous hike.
• Reduce sitting time, try to sit or lie down less throughout the day. Break up long periods of inactivity with a short walk or some light movement.
