Peter Attia MD - Should you start your workout with cardio or strength training?
The speaker discusses the flexibility in deciding whether to do cardio or resistance training first, emphasizing that it depends on individual goals and the intensity of the workouts. For instance, if a high-intensity V2 Max workout is planned, it should be prioritized over resistance training, especially if it's a rare occurrence. The speaker shares a personal example where they did a low-intensity Zone 2 cardio session in the morning and a leg resistance workout later in the day due to scheduling constraints. This approach worked well because the low load of the cardio did not affect the subsequent high-load resistance training. The speaker notes that the decision might differ if the workouts involved different muscle groups, such as upper body exercises, where the order might not matter as much.
Key Points:
- Prioritize the workout that aligns with your primary fitness goal.
- High-intensity workouts should be done first if they are infrequent.
- Low-intensity cardio can precede resistance training without negative effects.
- Consider muscle groups involved; order may not matter for different groups.
- Flexibility is key; adapt based on personal schedule and goals.
Details:
1. 🤔 Addressing Common Workout Queries
- Experts advise that performing resistance training before cardio can optimize strength gains and muscle growth, as fatigue from cardio might hinder performance during weightlifting exercises.
- If the goal is to increase cardiovascular endurance, doing cardio first could be beneficial, though it might compromise the intensity of subsequent resistance training.
- For balanced fitness goals, both approaches can be alternated, depending on the individual's primary focus for a particular workout.
- A study found that athletes who performed resistance training prior to cardio had a 20% higher increase in muscle strength compared to those who did cardio first.
2. 📝 Strategic Workout Planning: Prioritization

Osmosis from Elsevier - Inflammation - causes, symptoms, diagnosis, treatment, pathology
Inflammation is characterized by heat, pain, redness, and swelling, often leading to temporary loss of function. It can be triggered by pathogens, toxins, or trauma. The process begins with stimuli like pathogens or internal signals from damaged cells, recognized by pattern recognition receptors (PRRs) on immune cells. These receptors activate an inflammatory response, part of the innate immune system, which is non-specific and rapid. Key immune cells involved include granulocytes and agranulocytes, with neutrophils being the first responders. They phagocytose pathogens and damaged cells, eventually undergoing apoptosis. The complement system also plays a role by attracting leukocytes and aiding in pathogen destruction. The inflammatory response concludes with tissue repair, involving macrophages clearing debris, angiogenesis, and fibroblasts synthesizing collagen. If damage is mild, tissue regenerates; if severe, a fibrous scar forms.
Key Points:
- Inflammation is triggered by pathogens, toxins, or trauma, aiming to restore tissue balance.
- Key signs include heat, pain, redness, swelling, and potential loss of function.
- Pattern recognition receptors on immune cells detect harmful stimuli, initiating a rapid, non-specific response.
- Neutrophils are the first immune cells to respond, phagocytosing pathogens and damaged cells.
- The inflammatory response ends with tissue repair, potentially resulting in regeneration or scar formation.
Details:
1. 🔍 The Basics of Inflammation
1.1. Introduction to Inflammation
1.2. Key Signs of Inflammation
2. ⚡ Triggers of Inflammation: Pathogens, Toxins, and Trauma
- Inflammation can be triggered by pathogens, such as bacteria and viruses, which elicit an immune response to fight off infections.
- Toxins from environmental sources or lifestyle choices, like smoking, can lead to inflammation as the body attempts to neutralize harmful substances.
- Physical trauma, including intense exercise, causes inflammation as part of the healing process for damaged tissues and muscle fibers.
- Inflammation's primary goal is to respond to harmful stimuli and restore normal function, highlighting its role in both protection and healing.
3. 🦠 External and Internal Triggers: PAMPs and DAMPs
- Inflammation is initiated by external and internal triggers, essential for resolving tissue injury and facilitating repair.
- External triggers include allergens, irritants, toxic compounds, and microbial factors like virulence elements and pathogen-associated molecular patterns (PAMPs).
- Virulence factors allow pathogens to colonize tissues, while PAMPs, such as peptidoglycan and LPS in bacteria, and viral RNA or DNA, are molecular patterns common to pathogens.
- The immune system identifies these external elements as foreign, initiating an inflammatory response.
- Internal triggers involve damage-associated molecular patterns (DAMPs), released from intracellular proteins upon cell injury or death.
- DAMPs alert the immune system to significant cell damage and activate inflammation to repair the damage.
- Examples of DAMPs include heat shock proteins, high-mobility group box 1 (HMGB1), and ATP, providing signals for immune activation.
4. 🔬 Immune Recognition and Response Initiation
- Pattern recognition receptors (PRRs) on leukocytes identify pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs), initiating the immune response.
- PRRs can broadly categorize pathogens (e.g., distinguishing viruses from bacteria) but cannot identify specific pathogens, reflecting the non-specific nature of the innate immune response.
- The innate immune response is rapid, activating within minutes to hours, providing an immediate defense against pathogens.
- This response lacks memory; it does not become more efficient upon repeated exposure to the same pathogen.
- Examples of PAMPs include bacterial lipopolysaccharides and viral RNA, while DAMPs can be cellular components released during damage.
- PRRs and the innate immune response are crucial for the immediate defense and for signaling the adaptive immune system to mount a more tailored response.
5. 🧬 Leukocytes and the Inflammatory Cascade
- Leukocytes are categorized into two main types: granulocytes (neutrophils, eosinophils, basophils, mast cells) and agranulocytes (lymphocytes, monocytes).
- The inflammatory process typically begins with macrophages or mast cells in the tissues responding to damage signals (PAMPs or DAMPs).
- Mast cells release granules containing inflammatory mediators such as histamine, serotonin, cytokines, prostaglandins, and leukotrienes, which act on endothelial cells of nearby capillaries.
- These mediators cause endothelial cells to separate, increasing capillary permeability and allowing plasma proteins and fluids to exit the circulation.
- Macrophages ingest pathogens, acting as the body's garbage trucks, and release cytokines that further increase vascular permeability.
6. 🚀 Neutrophils, Complement System, and Adaptive Immunity
- Endothelial cells enhance leukocyte adhesion and rolling along vessel walls through increased expression of adhesion proteins, facilitating leukocyte migration to injury sites.
- Neutrophils, as first responders to infection, are drawn to sites of injury by chemokines and microbial products, where they undergo extravasation into tissues.
- Upon reaching the site, neutrophils rapidly engulf pathogens and debris through phagocytosis, followed by apoptosis to resolve inflammation.
- The complement system, composed of soluble proteins, is activated by antibodies or pathogen molecules, enhancing leukocyte attraction and aiding in opsonization.
- Complement proteins bind to microbes, promoting phagocytosis, and can form membrane attack complexes to directly kill pathogens.
- Neutrophils and the complement system work synergistically with macrophages and other immune cells to mount a coordinated immune response, enhancing pathogen clearance and tissue repair.
7. 🔄 Tissue Repair and Resolution
- Dendritic cells play a crucial role in pathogen defense and activation of the adaptive immune system, which begins its response after a few days.
- Platelets, along with clotting factors, are vital in forming blood clots that not only stop bleeding but also create a barrier against pathogen entry, setting a scaffold for tissue repair.
- Macrophages are essential for clearing dead cells and debris, thereby enabling the formation of new cells and tissue.
- Angiogenesis is a critical process initiated by growth factors from macrophages, leading to the formation of temporary blood vessels that are crucial during wound healing and regress once the tissue repair is complete.
- Fibroblasts are responsible for synthesizing collagen, a key component that supports the structural integrity of healing tissues.
- The extent of damage dictates the repair outcome: mild damage allows tissue regeneration to its original state, whereas severe damage results in replacement with scar tissue, which is typically nonfunctional.
8. 🧩 Recap of Inflammatory Process
- Inflammation is a complex response to harmful stimuli such as pathogens, trauma, or toxins.
- The response includes blood vessels dilating, becoming more permeable, and attracting immune cells and fluid into local tissue.
- Classical signs of inflammation include heat, pain, redness, and swelling, which may lead to loss of function.
- The inflammatory response concludes with wound repair and resolution, either restoring tissue integrity or resulting in fibrous scarring.
9. 📚 Focus on Learning and Growth
- Clinicians are encouraged to focus on learning, retention, and thriving in their roles.
- Implementing strategies that enhance learning and retention is key for the development of current and future clinicians.
- The emphasis is on sustainable growth through continuous education and skill enhancement.
- Specific strategies such as regular workshops, mentorship programs, and access to online courses can significantly improve learning and retention.
