Here’s How Long Cardio Exercises Should Last to Help You Lose Weight

When it comes to losing weight, cardio exercises are among the most effective ways to burn calories and shed extra pounds. But how long should you be doing cardio for the best results? Let’s break it down to help you create a workout routine that fits your goals, schedule, and fitness level.

Why Cardio is Key for Weight Loss

Cardio, or aerobic exercise, increases your heart rate, burns calories, and helps you create the calorie deficit needed to lose weight. It also improves heart health, boosts metabolism, and enhances stamina. However, the duration and intensity of your cardio sessions play a significant role in achieving weight loss.

The Optimal Duration for Cardio

The ideal length of a cardio workout depends on factors like your fitness level, weight loss goals, and the intensity of the exercise.

1. For Beginners

  • Duration: 20–30 minutes per session
  • Frequency: 3–4 times per week
  • Why: Helps build endurance without overwhelming the body.

2. For Intermediate Levels

  • Duration: 30–45 minutes per session
  • Frequency: 4–5 times per week
  • Why: Increases calorie burn and strengthens cardiovascular health.

3. For Advanced Levels

  • Duration: 45–60 minutes per session
  • Frequency: 5–6 times per week
  • Why: Maximizes fat burn and endurance while challenging the body.

Types of Cardio and Their Recommended Durations

Different cardio exercises require varying durations to be effective.

Type of CardioDurationWhy It Works
Walking30–60 minutesLow impact and suitable for all fitness levels
Running20–40 minutesHigh calorie burn in a short time
Cycling30–45 minutesBuilds leg strength and burns calories
Swimming20–30 minutesFull-body workout with high calorie burn
High-Intensity Interval Training (HIIT)15–30 minutesCombines short bursts of activity with rest

How Intensity Affects Duration

The harder you work, the shorter your sessions can be without compromising results.

1. Low-Intensity Cardio

  • Longer sessions (45–60 minutes) are needed to burn a substantial number of calories.
  • Example: Walking, light jogging.

2. Moderate-Intensity Cardio

  • 30–45 minutes is sufficient for effective calorie burn.
  • Example: Steady cycling, swimming.

3. High-Intensity Cardio

  • Short bursts of 15–30 minutes can yield the same results as longer sessions.
  • Example: HIIT, sprint intervals.

Factors That Influence Cardio Duration

1. Calorie Goals

  • To lose 1 pound, you need a deficit of 3,500 calories.
  • Cardio duration should align with your weekly calorie burn targets.

2. Body Type

  • Endomorphs may require longer cardio sessions for weight loss compared to ectomorphs or mesomorphs.

3. Diet

  • Combining cardio with a calorie-controlled diet reduces the need for excessively long sessions.
