Introducing the Garmin Forerunner 45 Series
Support: Getting Started with Garmin Forerunner® 45/45S

When you lace up your shoes and get ready to run, make sure you have the right tool for the job. Forerunner 45S is the smaller-sized GPS running watch with all the running-related features you need in a sleek, lightweight smartwatch that you’ll want to wear all day and night.

Run Your Heart Out

This easy-to-use running watch is perfect for daily runs, training sessions and even that upcoming 10K you got talked into. Built-in GPS tracks where you run and gives you accurate stats, including distance, pace and intervals. And its intuitive button interface makes it easy for sweaty hands to mark a lap or pause the timer. Forerunner 45S also monitors heart rate at the wrist, day and night.

Gear up with Garmin Coach

Whether you’re a seasoned runner or just getting off the couch, everyone can use a little bit of guidance. That’s why Forerunner 45S is compatible with Garmin Coach adaptive training plans. These plans feature guidance from expert coaches and free training plans that adapt to you and your goals. It’s a foolproof way to get to the finish line. As part of your training plan, it can even help you predict your race time. And the workouts sync right to your watch.

Stay Connected on the Run

Safety and tracking features make it easy to share your location with chosen contacts in case you need assistance — manually, or automatically with built-in incident detection. And a variety of connected features keeps you in touch with the rest of the world during and in between runs. Get smart notifications delivered to your wrist for incoming text messages and phone calls. And when paired with your compatible smartphone, Forerunner 45S will automatically upload your run data to the Garmin Connect online fitness community. It even has handy controls for the music playing on your phone, so you can skip songs without missing a beat.

There’s More to Do

With a dozen activity profiles available, you’ll always have a way to capture your sweat equity, even when you don’t feel like running. Forerunner 45S can record your efforts during a cycling workout, on the treadmill, indoor track and elliptical — and while doing cardio, yoga and more.

On the Way to Wellness

The Forerunner 45S GPS running watch offers extensive activity and wellness tracking features. Wear it 24/7 to monitor daily steps, distance, calories burned and even sleep. This smartwatch also features all-day stress monitoring for wellness tracking during the day. If your stress level starts to climb, use the relaxation breathing timer for a few minutes of guided breathing, which can help calm your mind and body. And to help you optimize your body’s energy, Body Battery™ energy monitoring uses collected data to gauge your energy reserves at any moment, so you can plan your day to optimize times for activity and rest.

Share and Compete

Syncing your activities to Garmin Connect is for more than just storing your data. Garmin Connect is a thriving online community where people on the go can connect and compete by joining challenges, encourage each other’s successes and even share their triumphs via social media. Garmin Connect is free and available on the web or on your smartphone.

A Better Way to Burn Fat 
 
If your weight-loss efforts seem stalled or stymied, heart-rate-based interval training may provide just the metabolic boost you need.  It’s not fair, you say: You’re eating right and you’re working out for hours every week, yet your unwanted fat is barely fazed – in fact, it’s just plain ignoring you. What gives?  Well, it could be that you haven’t yet trained your body to burn fat efficiently. Or it could be that you’ve adapted to your current program and, as a result, you’re burning fewer calories than you were a few months ago. Either way, stalled weight loss can be frustrating, but here’s the good news: Using strategic heart-rate training, you can drop those stubborn pounds.  Click here to learn a better way to burn fat.
 
Steady-State Cardio Vs. High-Intensity Interval Training
 
The best system of cardiovascular training probably isn’t the all-or-nothing approach. Rather, it’s a blend of both higher and lower-intensity cardiovascular training that’s tailored to your body and your goals.  Click here to discover why a blend of both high- and low-intensity exercise is the best system of cardiovascular training. 
 
Three heart-rate-based workouts that help you lose weight smarter and faster.
 
At some point in your fat-burning endeavors, you’ve probably been directed to take your pulse for a few seconds, then multiply that number to get your beats per minute. Perhaps you’ve grabbed the sensors on a treadmill to find out how hard you’re working — or just out of pure curiosity. And when you do, do you ever wonder: What’s the point? Can knowing your heart rate really help you reach your weight-loss goals? If you’re trying to drop unwanted pounds, not win a triathlon, does all that heart-rate stuff really matter?  Wonder no more: The answer is yes. It turns out that a fitness-by-numbers approach can churn out remarkable weight-loss results. It helps you upgrade your fitness, too, of course. But even if you don’t give a fig about fitness, heart-rate training is still a fat-blaster’s best friend.  Monitoring your heart rate helps you avoid the common mistake of always training in the same “gray zone” of intensity, says Troy Jacobson, head endurance sports coach at Life Time Fitness in Chanhassen, Minn. And that means you avoid wasting time and energy on workouts that don’t deliver the results you’re after. “Heart-rate training allows you to precisely control the intensity of your workouts to ensure you get the benefits you’re seeking — including fat loss.”  For more information on how to get started, click here
