Q&A's about heart rate

1. Q: What's the importance of heart rate in a CrossFit workout?

A: There are a couple important principles around heart rate in CrossFit.

1. Intensity: Workouts are designed to have varying degrees of intensity. Therefore, your heart rate should match the anticipated intensity of the stimulus of the workout. Sprint workouts are meant to bring the heart rate up near max, Zone 5, while other workouts might keep your heart rate lower in Zone 2 or 3. Understand the stimulus, or goal, of the workout and you'll be in the right zone!
2. Keep it Low: In most CrossFit workouts, as a rule of thumb, you want to keep your heart rate down so you can perform better. It doesn't serve you to be maxed out, breathing out of control while you back squat or deadlift. Similarly, if your heartrate is too high in a metcon, requiring you to rest, you'll be missing out on some of the benefits of that workout. So, a higher heart rate doesn't always serve you well.
3. Learn Your Body: Heart rate calculators on your smart watch are useful guides, but should not be relied on to be predictive of your effort. Meaning, you shouldn't use the heart rate guide on your watch to determine if you should speed up or slow down. Ideally, you are in tune with your perceived effort/output and base your intensity around your psychological readiness to train versus the heart rate metric on your watch.

2. Q: Why should I spike my heart rate before a workout?

A: Spiking your heart rate before a hard workout is beneficial for several reasons:

1. Preparation: Increasing your heart rate before a hard workout signals to your cardiovascular system that it needs to deliver more oxygen-rich blood to your muscles, priming them for activity.
2. Improved Performance: When your heart rate is already elevated, your muscles receive better blood flow, oxygen, and nutrients, which can improve endurance, strength, and overall workout performance.
3. Mental Readiness: Rapidly increasing your heart rate can also help you get mentally prepared for the intensity of the upcoming workout. It can sharpen focus, increase alertness, and mentally transition you into a state conducive to pushing yourself during the workout.
4. Injury Prevention: Gradually spiking your heart rate with a warm-up routine helps prepare your muscles, tendons, and ligaments for the demands of the workout, reducing the risk of injury. A proper warm-up increases tissue elasticity, range of motion, and muscle activation, making your body more resilient to the stresses of exercise.
5. Enhanced Energy Systems Activation: Elevating your heart rate before a hard workout activates your body's energy systems, such as the aerobic and anaerobic pathways, more efficiently. This allows for a smoother transition into higher-intensity exercise and optimizes energy production during the workout.

3. Q: How can I build a better cardio base?

A: Here are some steps to help you build better cardiorespiratory endurance:

1. Start Slowly: If you're new to cardio training or returning after a break, start slowly and gradually increase the intensity and duration of your workouts. This allows your body to adapt to the demands of exercise and reduces the risk of injury.
2. Consistency is Key: Aim for regular workouts, ideally at least three to five times per week. Consistency is crucial for building a cardio base as it allows your body to adapt and improve over time.
3. Gradually Increase Intensity: As your fitness improves, gradually increase the intensity of your workouts. Challenge yourself, but listen to your body and avoid overtraining.
4. Include Variety: Incorporate a variety of activities and training modalities into your routine. CrossFit is known for variety, so keep showing up with consistency!
5. Prioritize Recovery: Research and learn how to recover from your workouts well, including things like focused breathwork
6. Measure Progress: Keep track of your workouts, including duration, intensity, and how you feel during and after each session. This can help you identify trends, celebrate achievements, and adjust your training plan as needed to continue progressing.
7. Zone 2: Incorporate 40 min+ training sessions where your heart rate is in Zone 2. Zone 2 builds a strong foundation, allowing you to use Zones 3-5 more effectively!
