What Is Blood Pressure?

Blood pressure (BP) is the force that circulating blood exerts on the walls of your arteries. It's one of the most important indicators of cardiovascular health.

Your blood pressure is expressed as two numbers:

  • Systolic (top number): Pressure when your heart beats.
  • Diastolic (bottom number): Pressure when your heart rests between beats.
Example: A BP reading of 120/80mmHg means systolic = 120, diastolic = 80.

Why It Matters - Especially in Fitness

High or low blood pressure doesn’t just affect your long-term health, it impacts your daily training and recovery.

In Training:

  • Elevated BP can be a warning sign that your body is under too much stress, whether from overtraining, poor recovery, or lifestyle habits.
  • Low BP might make you feel lightheaded or dizzy during workouts, particularly in heat or after intense cardio.

In Recovery:

  • Chronic high blood pressure can limit oxygen delivery to muscles and organs, affecting how well your body repairs itself.
  • Good BP control supports better circulation, which means nutrients and oxygen are delivered efficiently, key for muscle growth, endurance, and recovery.

For Athletes and Lifters:

  • If you’re lifting heavy or training at high intensity, tracking your BP ensures you’re not risking hypertensive spikes.
  • It’s also a strong indicator of how your nervous system is responding to your training load.

Bottom line: Keeping your blood pressure in check isn’t just about avoiding disease — it’s about performing at your best, avoiding setbacks, and protecting long-term gains.


What’s Considered Normal?

What Affects Blood Pressure?

A wide range of lifestyle and health factors can impact your BP:

  • Diet (especially salt and alcohol)
  • Physical activity levels
  • Stress
  • Sleep quality
  • Caffeine intake
