What specialists say about Cardio Workout

Types of Cardio Exercises

There are various ways to get your cardio workout in. Below are some of the most popular forms:

• Low-Intensity Steady State (LISS):
  These activities are performed at a moderate pace for an extended period. Examples include brisk walking, cycling, swimming, and hiking. LISS is great for all fitness levels and promotes fat burning, improved endurance, and cardiovascular health.

• High-Intensity Interval Training (HIIT):
  This involves alternating between short bursts of intense exercise and recovery periods. HIIT is efficient and effective for improving cardiovascular health, burning fat, and building endurance in a shorter amount of time.

• Moderate-Intensity Continuous Training (MICT):
  These are steady-paced exercises performed at a moderate intensity for a longer duration, such as jogging, brisk walking, and swimming. MICT is excellent for building stamina and improving overall cardiovascular fitness.

Mental and Emotional Well-being

Cardio workouts are not only great for your physical health but also offer significant mental and emotional benefits. When you engage in cardiovascular exercise, your body releases endorphins, often referred to as the “feel-good” hormones.

These endorphins are natural mood boosters that help alleviate stress, reduce anxiety, and even combat symptoms of depression. The rhythmic nature of many cardio activities, like running or cycling, also provides a mental escape, helping to clear your mind and improve your overall sense of well-being.

Regular cardio can lead to better emotional resilience, helping you handle daily stress more effectively and improving your overall mental health.

 

Impact on Mental and Physical Health

Physically, muscle growth boosts metabolism, as muscles burn more calories than fat, aiding weight management and metabolic efficiency. Strong muscles improve posture, movement, and bone density, reducing injury risk and supporting longevity. Muscle quality, not just size, is a key predictor of aging outcomes, with abilities like jumping or standing quickly reflecting neuromuscular health. Intense exercise that produces lactate (felt as a “burn”) acts as a hormonal signal, enhancing heart, liver, and brain function, contributing to systemic health (Source: Huberman Lab Podcast).

Mentally, muscle growth indirectly enhances cognitive function. Lactate from intense workouts signals astrocytes in the brain, clearing debris and strengthening neural connections, potentially improving focus and memory. Regular resistance training at consistent times leverages biological clocks to enhance cognitive focus during non-training periods, aiding tasks like writing or problem-solving. Additionally, the discipline of structured training can foster mental resilience and clarity (Source: Huberman Lab Podcast, Galpin Interview).

How to Improve Behavior

1. Engage in Resistance Training 2-4 Times Weekly: Target major muscle groups with weights at 30-80% of your one-rep maximum, performing 6-12 reps near failure to stimulate hypertrophy. Use full range of motion for optimal results (Source: Huberman Lab Podcast, Galpin Interview).

2. Incorporate 10% Intense Efforts: Dedicate 10% of workouts to high-intensity efforts inducing a muscle “burn” to leverage lactate’s benefits for brain and organ health (Source: Huberman Lab Podcast).

3. Monitor Recovery with CO2 Tolerance Test: Assess recovery daily by inhaling deeply four times through the nose, exhaling through the mouth, then timing a slow exhale after a fifth deep inhale; aim for 30-120 seconds to ensure training readiness (Source: Huberman Lab Podcast, Galpin Interview).

4. Use Progressive Overload: Gradually increase weight, reps, or exercise complexity to challenge muscles and drive growth, avoiding plateaus (Source: Galpin Interview).

5. Avoid Anti-Inflammatories Post-Workout: Refrain from NSAIDs or antihistamines within four hours post-training to preserve inflammation needed for muscle adaptation (Source: Huberman Lab Podcast).

Foods, Additives, and Fluids

1. High-Quality Protein (Leucine-Rich): Consume 700-3000 mg of leucine per meal (e.g., eggs, chicken, fish) to support muscle repair and growth. Vegans may supplement leucine but should consult a doctor (Source: Huberman Lab Podcast).

2. Creatine Monohydrate (3-15 g Daily): Take 3-5 g for those under 180 lbs, up to 15 g for heavier individuals, to enhance power output, hydration, and cognitive function. May cause hair loss in some men; consult a physician (Source: Huberman Lab Podcast, Galpin Interview, Examine.com).

3. Beta-Alanine (2-5 g Daily): Supports muscular endurance by buffering acid buildup, ideal for 60-240 second efforts. Consult a doctor for safety (Source: Galpin Interview).

4. Sodium Bicarbonate (0.5 tsp in 10 oz Water): Drink 20-60 minutes before high-intensity training to delay fatigue by regulating pH. Start low to avoid gastric distress (Source: Galpin Interview).

5. Electrolytes (Salt, Potassium, Magnesium): Maintain hydration with electrolyte-rich fluids or foods like bananas to support nerve-to-muscle communication. Monitor intake if on diuretics (Source: Huberman Lab Podcast).

Summary

Muscle growth, or hypertrophy, enhances strength, metabolism, and mental clarity through resistance training. It boosts metabolism, improves posture, and counters age-related decline, while lactate from intense workouts supports brain and organ health. Train 2-4 times weekly with moderate weights, use progressive overload, and monitor recovery with the CO2 tolerance test. Avoid post-workout anti-inflammatories to preserve gains. Consume leucine-rich proteins, creatine, beta-alanine, sodium bicarbonate, and electrolytes to support muscle repair and performance. Consult professionals before supplementing. These evidence-based strategies improve strength, health, and cognitive focus, aligning with holistic wellness (Source: Huberman Lab Podcast, Galpin Interview, Examine.com).
