What is LionHeart 2.0?

LionHeart 2.0 is the updated version of the LionHeart tracking system. It uses industry-standard, dynamic formulas to provide more personalised heart rate targets and metrics for every member.

Instead of a “one size fits all” approach, LionHeart 2.0 factors in:

• Resting Heart Rate (RHR) – your heart rate at rest

• Max Heart Rate (MHR)

• Heart Rate Reserve (HRR) – the range between your RHR and MHR

This makes the point system more accurate for different fitness levels, ensuring targets are personalised to each user.

How Do Points Work?

LionHeart points are a fun way to measure workout intensity and keep members motivated.

The goal is:

• 45 points in a 45-minute workout

• 60 points in a 60-minute workout

Points are awarded based on how long you keep your heart rate at or above the Target HRR% for that workout type.

If you stay exactly at the target HRR% for the full session → you’ll earn the standard 45 (or 60) points.

Workout Targets in LionHeart 2.0

Each workout has its own Target HRR%; this is based on the average effort members across the network exert for that specific workout to hit a specific zone. 

FAQ

Why can’t I beat someone else’s score?

Points are based on heart rate. The fitter you are, the harder it can be to push your HR high enough to earn points quickly. That’s normal — and actually a sign of improved conditioning. Encourage members to focus on personal progress over time rather than comparing scores with others.

Important Note

LionHeart points and are a guide only. They should never replace medical advice. Members should:

• Listen to their body during training

• Adjust effort if they feel unwell

• Seek advice from a doctor if they have medical conditions or concerns

Resting Heart Rate (RHR) is defined by the Mayo Clinic as the heart rate "when the heart is pumping the lowest amount of blood you need because you're not exercising".

This is typically between 60 to 100 beats per minute, with a lower amount usually indicative of increased efficiency in pumping blood as a result of exercise and healthy lifestyle habits. 

There is no industry standard algorithm for calculating this, however default values can be estimated using age, gender, and athletic ability.

To find your resting heart rate manually (ideally as soon as you wake up):

Place your index and third fingers on your neck to the side of your windpipe. To check your pulse at your wrist, place two fingers between the bone and the tendon over your radial artery — which is located on the thumb side of your wrist.

When you feel your pulse, count the number of beats in 15 seconds. Multiply this number by four to calculate your beats per minute.

Max Heart Rate (Max HR) is the highest number of beats per minute your heart is able to achieve. It is used to help understand what target heart rate zones a person should be aiming for during exercise to achieve specific fitness goals.

The formula used by Lionheart to determine Max Heart Rate is:

HR Max = 208 - (0.7 X Age) *

* this is rounded up if needed

Heart Rate Reserve is, simply, the difference between your Resting Heart Rate (RHR) and your Max Heart Rate (Max HR).  

It is used to be able to determine the Heart Rate zones for an individual and is more accurate than simply using Max Heart Rate since it can be more personalised to a person's specific athletic ability.

Lionheart uses the industry standard Karvonen formula to determine the HRR:

HRR (Heart rate reserve) = Max HR - RHR

Heart Rate Zones are ranges of heart rates (as a percentage of either Max HR or Heart Rate Reserve) of increasing values that correspond to increasing levels of exercise intensity.

Lionheart 2.0 uses the Karvonen method of utilizing Heart Rate Reserve (i.e. taking into account a member's Resting Heart Rate and Max Heart Rate) to determine a person's heart rate zones.

The Heart Rate Zones and their respective formulas for Lionheart 2.0 are as below:

Zone 1 - Blue

Intensity: Very light / Recovery

(60% or less)  X HRR) + Resting HR

Zone 2 - Light Blue

Intensity: Light / Easy

((60 - 70%)  X HRR) + Resting HR

Zone 3 - Green

Intensity: Moderate

((70 - 80%)  X HRR) + Resting HR

Zone 4 - Orange

Intensity: Hard

((80 - 90%)  X HRR) + Resting HR

Zone 5 - Red

Intensity: Maximum

((90% or more)  X HRR) + Resting HR

The colors for each Zone in the F45 Training app and on the F45TVs for Lionheart 2.0 are as below:

Click on your profile picture on the top left of the F45 Training app, then click the ‘gear’ icon on the top right, then tap Lionheart > Heart Rate.

Lionheart bands use an industry-standard algorithm to estimate caloric burn based on this study.

Women:

Caloric Burn = T × (0.4472×H - 0.1263×W + 0.074×A - 20.4022) / 4.184

Men:

Caloric Burn = T × (0.6309×H + 0.1988×W + 0.2017×A - 55.0969) / 4.184

Where:

T – Duration of exercise in minutes;

H – Your average heart rate in beats per minute;

W – Your weight in kilograms; and

A – Your age in years.

All wearables have slightly varied hardware and software approaches to estimating calorie burn, and a range of factors such as body type, skin tone, age and more can have an effect on the accuracy of wearable calorie estimates.

The best way to use calorie burn estimates is to identify trends over time that indicate progressive improvements in efficiency. Typically, a person will reduce calorie burn for the same activity over time as their body adapts to it and becomes more effective at cardiovascular exertion. 

Activity Levels in Lionheart 2.0 are used in conjunction with your age and your sex to help determine the default Heart Rate Zone ranges for you.

The levels are:

Very Light - No exercise, sedentary work

Light - Exercise 1x per week, roughly 10k steps per day

Moderate - Exercise 3x per week, at least 10k steps per day, moderate intensity

Active - Exercise 5x per week with intense effort occasionally, at least 10k steps per day,

Vigorous - Athlete, Exercises 7 times per week and exerts intense effort often.

You might occasionally notice long, vertical bars appearing on your class report graphs. This visual anomaly typically stems from interference caused by other Bluetooth-enabled wearable devices you may have on, such as Apple Watches, Garmin devices, or WHOOP bands.

Why Does This Happen?

Bluetooth-enabled devices communicate using signals that can overlap or interfere with the LionHeart system's signal. When this happens, it disrupts the data being recorded, resulting in the appearance of these long, vertical bars on your graph.

How Can You Resolve This?

To ensure the accuracy of your class report graphs and enhance your LionHeart experience, we recommend either turning off the Bluetooth function on these wearable devices or choosing not to wear them during your LionHeart sessions.

Visual Example of Interference:

We understand how important accurate tracking is to your fitness journey and appreciate your cooperation in helping us provide the most accurate data possible.

If you notice a lower-than-normal heart rate on the heart rate monitor, follow these troubleshooting steps to resolve the issue.

Check 1 - Moisture and Skin Conductivity

Lack of moisture can lower the conductivity between the skin and the monitor, making it harder to detect your heart rate. For those who don’t sweat much, try adding water to the smooth contact pads on the inside of the strap before starting your workout.

Ensure there is no interference from hair, which can disrupt the monitor’s contact with the skin.

Check 2 - Wearable Bluetooth/ANT+ Device Interference

Any Bluetooth wearable device (e.g., Apple Watch) can interfere with the LionHeart signals. It’s best to turn off these devices or leave them aside during your workout to avoid signal disruptions.

Check 3 - Strap Fit and Placement

Make sure the strap is snug and securely against your chest throughout the workout. Some exercises may cause the strap to loosen or fall away from the body, so adjust it if necessary.

Check 4 - Incorrect/Outdated Profile Settings

Check that your profile settings are accurate and up-to-date, as these details are used to calculate your HR zones and calories.

In the F45 Training app:

• Tap your profile icon.
• Go to Update Details > Personal Information.
• Verify your height, weight, and date of birth.

Check 5 - Low Battery

Ensure your LionHeart monitor’s battery is charged or replaced (for v1 devices). Low battery levels can affect signal accuracy.

Check 6 - Try Another Device

If the above steps don’t resolve the issue, let your studio know about the problem. They can assist you in trying another device to determine if the issue is specific to your monitor or account.

Additional Notes

• Hair Interference: Ensure the strap is positioned on a hair-free area of the chest to maintain a solid connection.
• Battery Replacement/Recharge: Always keep the battery charged or replace it when necessary.
• Moisture Enhancement: If the monitor struggles to detect your heart rate, applying a bit of water to the smooth contact pads can improve conductivity.

If your heart rate tile is not showing on the LionHeart TV screen or you see 'guest', please follow these steps to address the issue:

1. Lionheart account setup in F45 Training app.

• Device Setup: Go to Settings -> Lionheart -> Add Device -> Enter your Sensor ID.

• Studio Connection: Go to Settings -> Lionheart -> Tap 3 dots on your device -> Update Sensor ID -> Add a Studio. Ensure your current studio is listed here and there are no error messages. If you see a 'connection failed' error, please complete this form: LionHeart Member form.
• Biometric Data: Go to Settings -> Lionheart -> Heart Rate. Ensure your biometric information is configured correctly.

2. Device Charge/Battery Check:

   - Version 2 (V2) devices: ensure that your device is fully charged. Low battery levels can prevent the device from functioning properly.

   - Version 1 (V1) devices: check if the battery needs replacing. A fresh battery is crucial for the device’s ability to transmit your heart rate data.

3. Proper Attachment of the Monitor: Ensure the heart rate monitor is snapped onto the strap correctly. The 'L' mark on the monitor should be aligned towards the left side of your chest, from your perspective, as shown in the image. This proper orientation is crucial for the monitor to function correctly and communicate with the LionHeart TV screen.

4. Chest Strap Adjustment: Verify that your chest strap is comfortably firm around your chest. The strap must be snug to maintain consistent contact but not so tight as to be uncomfortable.

5. Try Another Strap: If adjusting your current strap doesn't resolve the issue, try using a different strap. This can help determine if the problem is with the strap itself.

6. Moisture Application: Sometimes, dry skin or contact pads can hinder the connection between your chest strap and your skin. Lightly moisten the contact pads on the strap to improve conductivity and ensure a strong signal.

Additional Tips

• Warm-Up: Engaging in a light warm-up before your session can help increase your heart rate, making it easier for your device to detect and transmit your heart rate data.
• Skin Contact: Make sure the contact pads on the chest strap directly touch your skin, with no clothing in between.

The Lionheart Performance Tracker boards are designed to give you detailed post-workout feedback on your performance and recovery when using a Lionheart band or Apple Health. 

There are two boards: 

• Consistency Board - Tracks how often you train and how close each session is to the target. It rewards regular attendance and effort near the daily target.

• Discipline Board - Measures how closely your sessions align with the daily target. It rewards precision, not frequency.

For 45 minute classes, the target is 45 points and for 60 minute classes the target is 60 points. This number represents the optimum training load for a session, where the balance between effort and recovery is most effective.

The daily target is derived from looking at the effort of every single member globally for that specific workout (e.g. Redline, Athletica, Romans etc) and using the HRR% that represents the median. 

During the target calculation we also wash data for significant outliers and use studies-backed effort scales to ensure that the right % of the network fall within the target range.

Members who consistently get 45 points are more likely to see fitness and physiological benefits compared to those who regularly exceed the target for the same number of classes. 

The Consistency Board records your daily scores and calculates a weekly total. Additional bonus points are awarded if your daily score is close to the target. The closer you are to 45 points, the more effectively you are training based on your biometrics and the expected effort required for that specific workout. 

• Scores within five points of the target receive a +10 bonus

• Scores within three points receive a +15 bonus. 

This board emphasizes regular participation while rewarding steady performance near the target.

The Discipline Board calculates the percentage by which each workout score aligns with the daily target. A perfect score of 45 (or 60, depending on class length) results in 100%. The further your score is above or below the target, the lower the percentage. 

To have a weekly total appear on this board, you must complete at least three workouts within the week. 

This board highlights accuracy in meeting the intended training load irrespective of the number of days you work out. 

Scoring below the target suggests that your effort during the workout was lower than intended. Physiologically, this means your heart rate remained under the range designed to drive adaptation. 

Over time, repeated under-target scores may result in slower progress and reduced improvements in cardiovascular fitness.

As Lionheart is not a medical device, if you feel like you are unable to push harder yet are still getting low scores and you have confirmed your in-app biometrics are correct, please consult a doctor to understand this further. 

Scoring above the target indicates that your effort during the workout was higher than planned. Overtraining places additional stress on the body and the cardiovascular system and reduces the efficacy of workouts over time. 

Members who consistently get 45 points are more likely to see fitness and physiological benefits compared to those who regularly exceed the target for the same number of classes. 

This can increase fatigue, reduce recovery between sessions, and raise the risk of injury.

Remaining close to the target ensures that you are training at the level intended for that session. 

This promotes the best physiological outcomes, such as improved cardiovascular capacity, endurance, and recovery, without undertraining or overtraining. 

Achieving scores close to 45 points (or 60 depending on class length) should be considered the most effective and sustainable approach.

We have made numerous improvements to the algorithm and the targets to align closer to broadly accepted industry standards. The new algorithm and targets ensure that the awarded scores are objectively more accurate than prior iterations of Lionheart. 

If you feel like your score doesn’t reflect your effort, this is likely as a result of inaccurate biometrics in the F45 Training app. Ensure that your age, activity level, resting heart rate and max heart rate are accurate in the app. We typically find that members with points deviations from perceived effort have incorrect biometrics.

If you have confirmed your biometrics are accurate and your points are still not consistent with your perceived effort, speak to your coaches or a doctor to better understand your personal circumstances. 

Every workout has a different target HRR% to achieve the points target. The below guide will help you understand how you should feel during a workout for each HRR Zone:

Zone 1 (0-60% HRR): Breathing feels relaxed, you can hold a full conversation, and your muscles feel loose or warming up.

Zone 2 (60-70% HRR): Breathing is steady but noticeable, you can still talk in full sentences, and your muscles feel engaged but comfortable.

Zone 3 (70-80% HRR): Breathing is deeper, you can speak only in short phrases, and your muscles feel warm and working consistently.

Zone 4 (80-90% HRR): Breathing is heavy, you can only get out a few words, and your muscles are burning or starting to fatigue.

Zone 5 (90-100% HRR): Breathing is at your limit, talking isn’t possible, and your muscles feel at or near exhaustion.

If you are not on the in-studio Performance Tracker TV Boards, then you will appear in the in-app boards in the F45 Training App. This will be released in the coming weeks in an upcoming update.
