Can Cycling Cause Heart Problems?

Cycling is often praised for its heart-health benefits — and for good reason. It improves cardiovascular fitness, lowers blood pressure, and helps with weight control. But if you're a regular rider (especially a senior or endurance cyclist), you may have heard the question:

Can too much cycling actually hurt your heart?

Let’s dig into what science, doctors, and decades of cycling experience say about the real relationship between cycling and heart health.

❤️ The Good News: Cycling Is Great for Most Hearts

Study after study shows that moderate cycling reduces the risk of heart disease, stroke, and high blood pressure. Regular riders tend to have:

  • Lower resting heart rates

  • Improved cholesterol profiles

  • Better weight control

  • Reduced stress levels

The American Heart Association recommends at least 150 minutes of moderate aerobic exercise weekly — and cycling is one of the top choices.

So, for most people, riding your bike is one of the best things you can do for your heart.

⚠️ But What About Overdoing It?

Some headlines and studies have raised concern about the potential risks of extreme endurance cycling, especially for older athletes who push themselves over long periods.

Potential issues include:

  • Heart arrhythmias (like atrial fibrillation): Seen more often in long-term endurance athletes, especially men over 50.

  • Myocardial scarring: Rare, but has been observed in some ultra-endurance cyclists.

  • Overtraining Syndrome: Too much exercise with not enough rest can strain your cardiovascular and nervous systems.

🚨 Important note: These concerns typically apply to elite or ultra-distance riders pushing high-intensity efforts over many years — not casual or recreational cyclists.

🧠 What I’ve Learned as an Older Cyclist

As someone who’s been riding for decades, I take heart health seriously. I’ve known riders who went too hard, too often — and ignored signs their bodies were giving them.

But I’ve also known many who thrived well into their 60s, 70s, and beyond because they listened to their bodies, balanced effort with rest, and kept riding joyfully.

🛠 Smart Heart Tips for Cyclists (Especially Seniors)

✅ Get regular checkups
Even if you feel great, have your heart checked annually — especially after age 50.

✅ Pay attention to your heart rate
Use a heart rate monitor and learn your safe training zones.

✅ Rest and recover
Recovery isn’t weakness — it’s what allows your heart and muscles to grow stronger.

✅ Know your limits
Riding 5,000 miles a year doesn’t mean pushing hard every ride. Mix in low-intensity days.

✅ Watch for symptoms
Dizziness, chest pain, or irregular heartbeat? Stop and see your doctor.

🚴‍♂️ Bottom Line

For most of us — especially older adults — cycling supports better heart health when done smartly.

If you're riding at a comfortable pace, staying hydrated, resting regularly, and getting checked out when something feels off, you're on the right path.

So don’t fear the bike — ride it. Just remember to listen to your heart along the way.

Does Cycling Make Sciatica Worse? What Cyclists Need to Know Sciatica is no joke — the sharp, radiating pain that shoots down your leg can make even simple movements feel like a challenge. If you're a cyclist dealing with sciatica, you may be wondering: Is cycling helping me or making it worse? As with most things in health and fitness, the answer isn’t black and white. Cycling can both aggravate and relieve sciatica, depending on how you ride, how your bike is set up, and how your body responds. 🚫 When Cycling Might Make Sciatica Worse Cycling can contribute to sciatic pain if certain risk factors are present: Prolonged Sitting Extended time in the saddle can compress the sciatic nerve, especially with a hard or narrow seat. Repetitive Motion Pedaling can irritate the nerve over time, especially if you already have underlying inflammation or nerve impingement. Poor Bike Fit or Posture Hunching over handlebars or riding a bike that isn’t properly fitted can put additio...

  Cycling for Focus and Mental Clarity: How Two Wheels Can Clear Your Mind We all know cycling is great for physical health, but did you know it can also sharpen your mind and improve your ability to focus? Whether you’re struggling with concentration, battling anxiety, or just looking for a mental reset, hopping on a bike may be one of the most effective and enjoyable ways to boost your brainpower. 🚴 How Cycling Improves Mental Focus Cycling isn’t just exercise — it’s a cognitive workout. Here’s how: 1. Increases Blood Flow to the Brain When you cycle, your heart rate rises and blood flow improves — especially to your brain. This delivers more oxygen and nutrients, which can enhance memory, focus, and decision-making . 2. Puts You in a Meditative State Cycling forces you to pay attention: to your breathing, your cadence, the road ahead. This state of flow quiets distractions and trains your brain to focus on the present moment. 3. Reduces Stress and Anxiety Riding a b...

Why Should I Wear Padded Bicycle Shorts when Cycling?

Cycling is a fantastic activity with benefits for both physical and mental health. But whether you're riding for 5 miles or 50, one key to enjoying the experience is comfort —and that starts with what you wear. One of the most important gear choices you can make is investing in a quality pair of padded bicycle shorts . Personally, I wear bib shorts. I just like the feel but shorts are fine too. Here’s why padded shorts are essential for every cyclist: 1. Enhanced Comfort on Every Ride Long hours in the saddle can take a toll on your sit bones, groin area, and inner thighs. Padded bike shorts—also known as cycling shorts—feature built-in cushioning (often made of foam or gel chamois) placed exactly where you need it. This padding reduces friction and absorbs pressure , helping prevent chafing, saddle sores, and general discomfort. 2. Better Performance Through Reduced Distraction When you're not distracted by soreness, you can ride longer and more efficiently. Padded shor...
