When it comes to maximising your diving performance, recovery is just as important as training.  Every training session pushes your body out of balance, disrupting homeostasis and temporarily lowering performance. With proper recovery, your body not only returns to baseline but adapts and improves, increasing your stamina and strength over time. Understanding how recovery works and learning how to track it can help you train smarter, dive better, and stay energised for repetitive diving and the adventures ahead. The Role of Sleep in Recovery Sleep is your body’s most powerful recovery tool. During deep sleep, the body releases growth hormones that repair tissues, restore energy, and support immune function. It’s when your system resets physically and mentally. Quality sleep is the foundation of recovery, performance, and overall well-being. By understanding your sleep patterns, you can better gauge your readiness for your next dive or workout and perhaps adjust accordingly.  With Suunto Ocean, tracking your sleep is effortless; just wear your watch to bed, and it does the rest. Each morning, you’ll receive a sleep summary: total sleep time, estimated time awake, and periods of deep sleep. Over time, these nightly snapshots evolve into trends and you will see a bigger picture of how well you're resting and recovering. To view your sleep trend, swipe up from the watch face to open the Sleep widget. You’ll see your most recent sleep at a glance, along with a rolling 7-day graph that helps you recognise patterns whether you're consistently well-rested or starting to fall behind. Tracking your sleep consistency is just as important as tracking duration. Regular sleep and wake times help support your body’s natural rhythm, making recovery more effective and energy levels more stable. For deeper insight track your  HRV during sleep to better help you understand how your body responds to training, stress, and environment, even while you rest. Read more about how to use HRV to optimize recovery. Sleep isn’t just downtime it’s your body’s chance to reset, repair, and prepare. And now, with Suunto, it’s something you can understand better than ever. Using HRV to Optimize Your Training The Suunto Ocean tracks over 95 activity types, including diving, swimming, strength training, and more. Combined with HRV insights, it shows you when it’s time to push forward or pull back, ensuring a sustainable training rhythm that supports long-term performance. HRV measures the tiny fluctuations in time between your heartbeats. It's one of the most reliable indicators of recovery and nervous system balance. A high HRV often signals that you are well rested and ready to perform. HRV isn't just a stat it’s a decision-making tool. By keeping an eye on it daily, you can tailor your training intensity, prevent overtraining, and improve overall resilience. High HRV: Your system is adaptable and recovered. Green light for more intensity. Low HRV: Your body is still under stress. Time to scale back or rest.Suunto Ocean monitors your HRV during sleep and after workouts, offering key insights into how your body is responding to stress and recovery. Balancing Stress and Recovery Peak performance comes from balance. The Suunto Ocean helps you understand your training load versus your recovery status. If your load is high and recovery is low, that’s your cue to rest before fatigue turns into burnout or injury. Technology is powerful, but your body’s signals are just as important. If you're feeling unusually sore, fatigued, or mentally drained, listen to those cues. Use the Suunto Ocean as a guide, but always tune into how you feel after your dive or your workout. Your body knows when it needs rest, and you just need to listen. Conclusion: Rest Smarter, Dive Stronger Recovery isn’t downtime it’s a performance tool. With the Suunto Ocean, you gain access to powerful recovery metrics like HRV, sleep quality, and training load all in one device. Prioritize rest, train with intention, and give your body what it needs to reach new depths. Because the better you recover, the better you dive.

Training intensity plays a crucial role in preparing for scuba diving. It’s not just about hitting the gym or logging endless cardio, but finding the right workout intensity is the key to getting the best results, whether you want to improve your diving fitness, breath hold or boost your endurance. What Are Training Zones? Training zones are intensity levels that help you follow a training plan and reach progress. Each zone targets different physiological systems, helping you build the endurance, power, and control you need for scuba diving. Here’s a breakdown of the most important zones for divers: Zone 1 – Recovery Used for warm-ups and active recovery. It promotes blood flow, aids in muscle repair, and helps ensure you’re not overtraining before a dive. Exercising in zone 1 is relatively easy on your body. When it comes to fitness training, intensity this low is significant mainly in restorative training and improving your basic fitness when you are just beginning to exercise, or after a long break. Every day exercises like walking, climbing stairs, and cycling to work are usually performed within this intensity zone. Zone 2 – Endurance This is your base-building zone. It improves aerobic efficiency and stamina, perfect to prepare you for long dives or extended underwater activity. Exercising at this intensity feels easy, but workouts with a long duration can have a very high training effect. The majority of cardiovascular conditioning training should be performed within this zone. Long duration workouts in this zone consume a lot of energy, especially from your body’s stored fat. Think steady swims or long-distance walking. Zone 3 – Tempo / Steady Effort Exercising in zone 3 begins to be quite energetic and feels pretty hard going. It will improve your ability to move quickly and economically, ideal for when you want to  improve your finning,  buoyancy control, and dive longer dives. This zone boosts moderate-intensity endurance that you rely on for continuous underwater movement. Zone 4 – High Intensity This is where power is built and limits are tested. Training in Zone 4 pushes your anaerobic system, improving your ability to perform in high-stress, physically demanding situations like hauling gear or responding to emergencies underwater. It’s fast, hard, and effective: a zone that rapidly boosts performance and resilience. But it’s not for every day, as too much intensity without recovery can lead to burnout or injury. Use it wisely, and Zone 4 becomes your edge when the pressure’s on. Zone 5 – Maximum Effort This is your redline, the zone of short, explosive bursts where you're pushing at full capacity. Training here targets your VO₂ max and anaerobic threshold, sharpening your body’s ability to respond quickly and powerfully under pressure, giving an edge in critical dive scenarios. Zone 5 efforts are intense and brief, lasting only minutes. They demand full focus and come with a high recovery cost, which is why elite athletes use them sparingly and strategically. For most fitness enthusiasts, this zone is optional as they are not required, but if you are chasing peak performance, include maximum-intensity workouts in your training program. How to Calculate and find your heart rate zones It is important to know your zones to be able to follow a training plan and to keep structure in your training. Use the classic formula (220 – your age) to estimate your max heart rate. You can build your zones off this baseline, but refine it as you get more experience. Once you know your zones, you can focus on gradual progression, tailoring each session to meet your diving goals. The Suunto Ocean makes zone-based training easy. Use its built-in heart rate monitor and analytics to track how your body is responding to each workout.  Start with a basic estimate, then refine as you go with data from your training sessions or tests. Suunto’s tools help you track it all so your training stays intentional, efficient, and aligned with your underwater ambitions.  Why Zone-Based Training Matters for Divers Each zone develops different capabilities from long-haul endurance to explosive power. By mixing the right training intensity with purpose, you’ll condition your body for more efficient movement, better recovery, and improved control underwater.  As Suunto expert Janne Kallio says: “Training doesn’t need to be complicated.”

Here’s the full list of activity types supported by your Suunto watch – plus how to track any new ones you may come up with. At Suunto, we believe in adventure. That’s why our products are built to be versatile, ready for whatever challenge you take on. When tracking different activities, two key terms are important to understand: activity types and sport modes. Activity types define the general nature of movement. Common examples include running and cycling. These serve as the foundation for training summaries in the Suunto app. Sport modes are specific configurations within an activity type, tailored to different workouts or environments. For example, an interval running session requires different data fields than a long endurance run. Sport modes determine what metrics (e.g., heart rate, speed, power, altitude, lap data) are displayed on your watch, what kind of screen layouts are used, and whether external sensors (e.g., heart rate belts, power meters) are connected. Your Suunto watch comes with dozens of ready-made sport modes, but you can also customize your own in the Suunto app. When you start an activity on your Suunto watch, you select a sport mode (e.g., "Interval Running"). Once synced to the Suunto app, the recorded data is categorized under an activity type (e.g., "Running"). You can also edit the activity type in the Suunto app if needed (e.g., changing "Running" to "Trail running"). Update: March 2025 – New activity types added  One of the new activity types is Splitboarding. (Image by Jaakko Posti / Arctic Lines)   We’ve expanded our supported activity types to better match the ways you move. Some of the new ones are: Cross-country skiing: Now split into Skate skiing and Classic skiing, so you can track each discipline separately. Prefer a general category? The existing Cross-country skiing type remains. Also, Biathlon is added as its own activity type. Backcountry skiing & Ski mountaineering: Perfect for adventurers exploring the mountains and backcountry. Splitboarding: Gliding on snow isn’t only for skiers. Snowboarders can now track their human powered endeavors as Splitboarding. Yoga & Pilates: Track your practice with more precision. Wheelchair & Handcycle: Whether you're training or commuting, you can now log your wheelchair or handcycling activities. E-Biking & E-MTB: Separate your electric-assisted rides from traditional cycling sessions. Chores: From mowing the lawn to shoveling snow, track everyday physical activity and get insights into your overall workload. What happens to your statistics when new sports are added? Track running is still running in your Suunto app summary data. (Image by Phil Gale, Soar)   How can you track your overall running or skiing kilometers in the future? If you record cross-country skiing as "skating," the summary tool in the Suunto app will list it separately from "classic skiing." The same applies to different types of running – track running, treadmill running, running, and trail running all appear as separate sport types. However, in the Training Zone in Suunto app, total running load combines all types of running into a single metric. This means you can track new sports both individually and as part of a larger category, giving you flexibility in how you analyze your training.

No problem! You can still track it:  Create a custom sport mode Build a Custom sport mode in the Suunto app to see exactly the metrics you want during the session. Use "Other" as the activity type, or use an existing activity type (e.g., a new sport mode for running). Use tags for better organization After syncing your activity to the Suunto app, go to "Edit" → "Add tag." Tags help categorize activities. For example, you can tag all races with "Race" or specific workouts with "Intervals."
