Why Start Running? The Benefits of Running

• Boost Cardiovascular Health: Running is a fantastic cardio workout. It strengthens your heart, improves circulation, and can lower blood pressure over time.
• Accelerate Weight Loss: While weight loss shouldn’t be the sole focus, it’s often a welcome side effect of regular running. Running is a high-intensity exercise and burns calories with high efficiency.
• Improve Mental Well-being: The “runner’s high” isn’t a myth! Running releases endorphins, which can boost mood and reduce stress. Many runners say their self-esteem and body image improve as they progress.
• Strengthens Bones and Muscles: Running is a weight-bearing exercise that helps strengthen your lower-body muscles (like quads, hamstrings, and calves) and can even increase bone density. Studies show that regular weight-bearing activity can slow bone loss and build stronger bones.

Consult Your Doctor Before You Begin

When learning how to start running when overweight, it behooves you to consult your doctor. They can:

• Assess your health and fitness level
• Identify any potential risks or limitations
• Provide personalized advice based on your medical history
• Recommend any necessary precautions or modifications

Getting medical clearance gives you peace of mind that you’re ready to start. It also establishes a baseline – you’ll be able to see how much your health improves as you progress.

Get the Right Gear (Shoes, Clothing, and Gadgets)

Investing in the right gear can make a world of difference when you’re starting to run. Here’s what you need to focus on:

Find the Right Running Shoes

Your feet are your foundation, so choose your running shoes wisely. Look for:

• Proper cushioning to absorb impact
• Good arch support
• A wide toe box for comfort
• Stability features if you overpronate

Pro tip: If possible, try them on in the evening (when feet are a bit swollen) and with the same socks you’ll run in. Good shoes might cost a bit more, but they’re a smart investment in your comfort and injury prevention.

Choose Comfortable, Chafe-Free Clothing

Comfort is key when it comes to running clothes. Opt for:

• Moisture-wicking fabrics to keep you dry
• Breathable materials for temperature regulation
• Compression shorts to prevent chafing

Remember, you don’t need to break the bank. Start with a few quality pieces and build your running wardrobe as you progress.

Consider a Fitness Tracker or App (Optional)

While not mandatory, some beginners find that wearable tech and apps add motivation and structure:

• Fitness Trackers/Smartwatches: Devices like a Fitbit, Garmin, or Apple Watch can track your distance, pace, heart rate, and steps. Seeing your progress in real time can be motivating. For example, monitoring your heart rate variability ensures you’re not overexerting – aim to run at a pace where you can still speak in sentences (the “talk test”). Some trackers can also alert you when it’s time to run or walk if you’re doing intervals.
• Headphones & Music/Podcasts: A good playlist can be incredibly motivating, and it can help distract from the discomfort when you’re starting out. If you enjoy music or podcasts, consider using headphones (preferably wireless and sweat proof). Just keep the volume safe and be aware of your surroundings, especially if running outdoors near traffic.
• Running Apps: Smartphone apps (free or paid) can serve as virtual coaches. Apps like Couch-to-5K (C25K), Adidas, or Runna offer beginner-friendly training programs and audio cues. They’ll tell you when to run, when to walk, and gradually increase your running intervals over weeks. I started off with Adidas first because it was free, then as my training progressed and I wanted more features (like syncing to my Fitbit), I switched to Runna for a modest fee.

Warm Up, Stretch, and Stay Flexible

When you’re eager to start running, it’s tempting to just dash out the door. However, skipping warm-ups or stretches is a common rookie mistake that can lead to injury, especially for heavier runners. Incorporating flexibility and mobility work will ensure your body is prepared for the impact of running.

Pre-Run Warm-Up Routines

Before you run, focus on dynamic stretches to warm up your muscles:

• Leg swings: Hold onto a wall for balance and swing each leg forward and back, then side to side. This helps loosen your hips and hamstrings.
• Arm circles: Make large circles with your arms, both forward and backward. This warms up your shoulders and upper back.
• Gentle lunges: Step forward into a lunge, then return to standing. Alternate legs. This stretch targets your quads and hip flexors.
• High knees: Jog in place, lifting your knees high toward your chest. This warms up your legs and gets your heart rate up.

Post-Run Cool-Down and Stretching

After your run, cool down with a 3-5-minute walk, then move into these static stretches:

• Hamstring stretches: Sit on the ground with one leg extended and reach for your toes. Hold for 15-30 seconds, then switch legs.
• Quadriceps stretches: Standing on one leg, bring your heel towards your buttocks and hold your foot with your hand. Keep your knees close together. Hold, then switch legs.
• Calf stretches: Step one foot forward, keeping the back leg straight. Lean forward, feeling the stretch in your back calf. Hold, then switch legs.
• Hip flexor stretches: Kneel on one knee, with the other foot flat on the ground in front of you. Push your hips forward with a soft motion, feeling the stretch in the front of your hip. Hold, then switch sides.

Hold each stretch for 15-30 seconds, focusing on your breathing and relaxing into the stretch.

Tip: Don’t bounce during stretches (it can cause muscle tears). And if a particular muscle feels very tight, that’s a sign to give it a little extra love. On rest days, doing a short yoga routine or using a foam roller can also work wonders for flexibility and recovery.

Follow a Gradual Run-Walk Plan (Couch-to-5K Method)

Alternating running with walking lets your body adapt safely. As your endurance grows, walking breaks shrink until you run continuously.

Sample 8-Week Schedule

Week	Run	Walk	Total Time
1	1 min	4 min	20–25 min
2	2 min	3 min	20–25 min
3	3 min	2 min	25–30 min
4	4 min	1 min	25–30 min
5	5 min	1 min	30 min
6	8 min	2 min	30 min
7	15 min continuous jog	—	20–25 min
8	25–30 min continuous jog	—	30–35 min

• Frequency: 3 sessions/week (e.g., Mon, Wed, Sat).
• Flexibility: Repeat any week if it’s too difficult; progress at your own pace.
• Apps: Use an app for on-screen cues and tracking.

Feel free to repeat any week if you’re not ready to progress. Everyone adapts at their own pace. It might take 10–12 weeks to comfortably run a 5K, and that’s perfectly fine.

Proper Running Form

After running for 30 years, here are the five best pieces of advice I’ve learned:

• Maintain good posture: Head up, shoulders relaxed, slight forward lean
• Arms swing like pendulums: Imagine there is a barrier down the middle of your body that prevents you from swinging your arms across it. This will increase your running efficiency and reduce stress on your neck and shoulders.
• Feet land under the body: This is the safest and most ergonomic way for your body to absorb the load of your foot striking the ground. I see so many runners’ feet mistakenly reaching and landing ahead of their bodies.
• 80% of weight should land midfoot: So many runners land on their heels, which is a side-effect of reaching your feet out in front of you and striding too long.
• Cadence: Some experts recommend a cadence of 180 strides per minute to shorten strides and reduce the forces that contribute to injury. This is sage advice. At my age, I am gassed at 180 and am more comfortable around 150. The key isn’t the number; it is shorter strides.

Good form might feel a bit unnatural at first, but with practice it becomes second nature. The result will be a more efficient stride – meaning you use less energy for the same distance – and fewer aches.

One more tip: breathe! New runners often get winded quickly; some of it is just fitness building, but some is due to shallow breathing. Try to breathe deeply from your belly (diaphragmatic breathing). Ensuring you get enough oxygen will help you avoid side stitches and dizziness.

Prevent Injuries: Listen to Your Body and Build Strength

Injury prevention is crucial, especially when you’re starting out. Be aware of these common injuries:

• Shin splints: Pain develops along the front of the shin, which is often caused by bad form.
• Knee pain: Can be caused by improper form or weak supporting muscles. Proper warm-ups and stretching help prevent this.
• Plantar fasciitis: Pain in the heel or bottom of the foot. Often worse in the morning or after periods of rest.
• Lower back pain: Can be caused by weak core muscles or poor posture while running. Strengthening your core with a supplemental mat Pilates program will help.

If you experience persistent pain, stop running and consult a healthcare professional.

Make Rest and Recovery a Priority

It might sound counterintuitive, but one of the most important parts of training is rest. Especially as a beginner (and even more so if you’re heavier), your body needs time to adapt to the stresses of running. Make sure to:

• Take rest days between runs
• Get adequate sleep
• Stay hydrated: this includes drinking water and other ways to stay hydrated
• Fuel your body with nutritious, plant-based foods

Remember, progress isn’t linear. Some days will be better than others, and that’s okay.

Running in Different Weather: Hot, Cold, and Rainy Days

Listen to your body and use common sense. In the military we had a saying: “If it ain’t rainin’, we ain’t trainin’.” While running in adverse conditions builds mental toughness, it’s not always the best approach for health – I learned that after catching more colds than I’d like. Here are some weather tips:

Staying Safe in the Heat

• Run in the early morning or late evening
• Wear light, breathable clothing, long sleeves, and hats
• Stay hydrated: Camelbaks are great for carrying water without having to lug a bottle on your run
• Listen to your body and slow down if needed

Braving Cold Weather

• Dress in layers and take them off as you sweat to avoid soaking through your clothes
• Protect your extremities with gloves and a hat
• Warm up indoors before heading out
• Be cautious of ice and snow. Traction is more important than speed.
• Remember to hydrate. Cold air can be dry, and you still sweat under those layers.

Rainy or Windy Days

• Rain Gear: Choose moisture-wicking clothes (avoid cotton, which becomes heavy when wet). For heavier rain, you might simply reschedule or use a treadmill – running with soaked clothes and shoes can cause blisters.
• Mind the Wind: If you must run in the wind, start your run heading into the wind and finish with it at your back. That way the hardest part is done first, and you won’t be chilled by wind on your sweaty body at the end.
• After the Run: When you finish a run in cold or wet conditions, change out of damp clothes as soon as you can and get warm. Have a towel and dry clothes or a blanket in your car if you drive to a trail.

Staying Motivated and Confident on Your Running Journey

Every fitness journey has its highs and lows. Motivation can surge when you start a new program, but inevitably there will be days when you feel discouraged, lazy, or insecure. This is completely normal. The key is to have strategies to keep yourself going when the initial excitement wears off or when life throws you off track. Here’s how to keep your running spark alive:

Overcoming Self-Consciousness

• Remember Every Runner’s Story: Almost every runner, even that fast marathoner you see, started as a beginner. The truth is, other people are usually too focused on their own workout or life to judge you.
• Choose Your Environment: If you’re very nervous at first, pick running locations where you feel comfortable. That might be a quiet side street, a local park trail, or even laps around your block when fewer people are out.
• Dress the Part: Wear clothing that makes you feel good. Good shoes and gear can also give a psychological boost – you feel like a “real runner” in them.
• Positive Self-Talk: Be your own cheerleader. Instead of “Everyone will laugh at me,” reframe it: “I’m proud of myself for showing up.”

Setting Realistic Goals and Milestones

• Short-term goals: These are milestones over the next few weeks or 1-2 months. “Complete a 30-minute workout without extra breaks,” or “Run non-stop for 1 mile,” or even “Jog at least 3 days each week this month.”
• Long-term goals: This could be something like “Run a 5K race in 3 months” or “Lose 20 pounds in 6 months through running and diet” or “Be able to run 30 minutes straight by the end of the year.”
• Make your goals specific and achievable: SMART (Specific, Measurable, Achievable, Relevant, Time-bound) goals are a good tool.
• Celebrate Milestones: Did you finish Week 2 of training? Run your first continuous mile? Hit a new personal distance record? Acknowledge it and reward yourself!

Building a Support System

• Find a Running Buddy or Group: Do you have a friend or family member who might join you for easy runs or walks? A workout buddy provides accountability – you’re less likely to skip a run if someone is waiting for you.
• Online Communities: There are countless online forums, Facebook groups, or apps (like Strava) where you can connect with other beginner runners.
• Share Your Goals with Close Ones: Let your family and close friends know about your running goals. Having people ask, “How’s your training going?” can keep you accountable.
