One of the most frustrating experiences for surfers is running out of gas mid-sessionâarms burning, lungs screaming, watching perfect waves roll by because you can't paddle back out. If you want to surf longer and catch more waves, you need the right cardio for surfing.
But here's the problem: most surfers approach surf endurance training completely wrong. They either rely entirely on surfing itself for conditioning, or they waste time on generic cardio that doesn't translate to paddle performance.
This guide will show you exactly how to build paddle endurance that actually improves your surfing, including:
- Why traditional cardio fails surfers
- The energy systems that matter for surfing
- Proven surfing cardio workouts that build real paddle power
- How to structure your surf endurance training
- Common mistakes that sabotage progress
Why Most Cardio for Surfing Doesn't Work
Many surfers assume that any cardio is good cardioâlong slow runs, boring bike rides, hours on the ellipticalâhoping it will improve their paddle endurance. It doesn't.
Here's why traditional cardio falls short as cardio for surfing:
- Wrong movement patterns: Running and cycling don't train the pulling muscles used in paddling
- Wrong energy systems: Surfing requires repeated bursts of high-intensity effort, not steady-state endurance
- Missing power component: Paddling into waves requires explosive power, not just aerobic capacity
- No shoulder stability: Generic cardio does nothing for the shoulder health that's critical for long surf sessions
The best cardio for surfing must match the actual demands of surfing: repeated high-intensity paddling bursts with incomplete recovery between sets.
The Energy Systems That Matter for Surf Endurance Training
To design effective surf endurance training, you need to understand how surfing actually uses energy.
Surfing is NOT Steady-State Cardio
Research shows a typical surf session breaks down like this:
- 50-60% paddling (mixture of moderate and high-intensity efforts)
- 28-30% waiting (low intensity but not full rest)
- 5-8% wave riding (near-maximal intensity)
- 3-5% duck diving (very high intensity bursts)
Notice the pattern? Surfing is dominated by repeated intervals of moderate to high-intensity paddling with incomplete recovery.
The Three Training Zones for Surfing
Understanding training zones and the anaerobic threshold is critical for building effective surf endurance training. Here's how they apply to surfing:
1. Aerobic Zone (Below Aerobic Threshold)
- Fuels extended paddling and recovery between waves
- Uses primarily fat for fuel, can be sustained for long durations
- Think: paddling back out after a wave at comfortable pace
2. Threshold Zone (At or Near Lactate/Anaerobic Threshold)
- The most important zone for surfing performance
- The maximum sustainable intensity before lactate accumulates rapidly
- Allows repeated hard paddling efforts without excessive fatigue
- Think: catching multiple waves in a set, paddling through impact zone
3. Anaerobic Zone (Above Anaerobic Threshold)
- Very high intensity, can only sustain for short bursts (seconds to minutes)
- Critical for explosive paddling into steep waves
- Lactate accumulates faster than it can be cleared
- Think: that final explosive burst to catch a critical wave
The best cardio for surfing trains all three zones strategically, with emphasis on threshold zone development where most surfing happens.
The Best Cardio for Surfing: 4 Proven Methods
These surfing cardio workouts are specifically designed to build paddle endurance and match the actual demands of surfing.
1. Interval Swimming: The Gold Standard for Paddle Endurance
Swimming is the most surf-specific cardio for surfing because it:
- Uses the exact same pulling muscles as paddling
- Forces horizontal body position
- Builds shoulder stability and endurance
- Can be precisely structured for different energy systems
High-Intensity Paddle Endurance Workout:
- 100m hard freestyle
- 60 seconds rest
- Repeat for 8-12 rounds
Purpose: Builds lactate threshold for repeated hard paddling efforts
Moderate Aerobic Base Workout:
- Swim continuously for 20-30 minutes at conversational pace
- Focus on technique and breathing rhythm
- Use pull buoy to emphasize upper body
Purpose: Develops aerobic base that supports recovery between hard efforts
Sprint Power Workout:
- 25m maximum effort freestyle
- Full recovery (90-120 seconds)
- Repeat for 6-10 rounds
Purpose: Builds explosive paddling power for catching steep waves
2. Rowing Intervals: Land-Based Paddle Power
Don't have access to a pool? The rowing machine (erg) is the next best option for surf endurance training.
Rowing trains:
- Pulling pattern similar to paddling
- High-intensity repeated efforts
- Full-body conditioning
- Minimal joint stress
Standard Surf Rowing Workout:
- Row 500 meters at hard effort (around 90% max)
- Rest 90 seconds
- Repeat for 6-8 rounds
Purpose: Mimics the repeated hard paddle-outs between wave sets
Long Paddle Endurance Workout:
- Row continuously for 20 minutes at moderate intensity
- Maintain consistent pace (around 70-75% max effort)
Purpose: Builds aerobic base and mental toughness for long sessions
3. Assault Bike or Airdyne: Brutal Surf Conditioning
The assault bike (where arms and legs work together) is underrated cardio for surfing because it:
- Trains full-body conditioning
- Allows infinite resistance scaling
- Creates massive conditioning stimulus
- Can be done anywhere with minimal space
Paddle Out Simulation Workout:
- 30 seconds maximum effort
- 60 seconds easy pace (don't stop moving)
- Repeat for 10-15 rounds
Purpose: Simulates paddling hard through sets with active recovery
Threshold Builder:
- 5 minutes hard effort (sustainable but uncomfortable)
- 2 minutes easy recovery
- Repeat for 4-6 rounds
Purpose: Extends your lactate threshold for longer sustained paddling
4. Paddle-Specific Circuit Training
Don't have access to any cardio equipment? You can build serious paddle endurance with bodyweight circuits that combine pulling movements with conditioning.
Surf Conditioning Circuit (repeat 5-8 rounds):
- 20 Band Straight-Arm Pulldowns (paddle simulation)
- 15 Push-ups
- 15 Burpees
- 20 Mountain Climbers
- Rest 60 seconds between rounds
Purpose: Builds pulling endurance with full-body conditioning
The key is keeping rest periods short and effort highâjust like paddling in the ocean.
How to Structure Your Surf Endurance Training Program
Having the best surfing cardio workouts means nothing if you program them wrong. Here's how to structure your surf endurance training for maximum results.
Training Frequency
If you're surfing 3-4+ times per week:
- Add 1-2 dedicated cardio sessions
- Focus on high-intensity intervals (lactate threshold work)
- Keep volume moderate to avoid overtraining
If you're surfing 1-2 times per week:
- Add 2-3 dedicated cardio sessions
- Include one longer aerobic session for base building
- Add 1-2 high-intensity interval sessions
If you're not currently surfing (injured or no waves):
- 3-4 cardio sessions per week
- Mix of long aerobic work and high-intensity intervals
- Maintain paddle-specific strength training
Weekly Surf Endurance Training Template
Week 1-4: Build Aerobic Base
- 2x longer aerobic sessions (20-30 minutes moderate intensity)
- 1x interval session (longer intervals with more rest)
Week 5-8: Threshold Development
- 1x aerobic session (maintenance)
- 2x lactate threshold intervals (sustained hard efforts)
Week 9-12: Power and Peak
- 1x aerobic session
- 1x threshold session
- 1x sprint power session (short, explosive intervals)
Recovery Guidelines
Cardio for surfing should enhance your water time, not destroy it:
- Schedule hard cardio sessions on non-surf days when possible
- If you surf and do cardio same day, keep intensity moderate
- Take at least one complete rest day per week
- Back off if shoulders feel chronically fatigued
Common Surf Endurance Training Mistakes
Avoid these mistakes that sabotage paddle endurance:
Mistake #1: Only Using Steady-State Cardio
Long, slow cardio builds general aerobic fitness but doesn't match surfing's repeated high-intensity efforts. You'll have great endurance at a pace that's too slow to be useful in the surf.
Fix: Emphasize interval training that mimics surf-specific intensities.
Mistake #2: Neglecting the Aerobic Base
The opposite mistake: only doing hard intervals without building aerobic base first. You'll burn out quickly and accumulate fatigue.
Fix: Build aerobic base in early phases before focusing on high-intensity work.
Mistake #3: Using Non-Paddle-Specific Cardio
Running has its place, but it doesn't train the pulling muscles or shoulder endurance you need for paddling. Your legs will be in great shape, but your paddle power won't improve.
Fix: Prioritize swimming, rowing, or pulling-based conditioning circuits.
Mistake #4: Training Too Hard, Too Often
More is not always better. Excessive cardio volume without adequate recovery leads to overtraining, decreased performance, and injury risk.
Fix: Focus on quality over quantity. 2-3 well-structured sessions beat 6 junk sessions.
Mistake #5: Ignoring Paddle-Specific Strength
Cardio for surfing builds endurance, but you also need strength. Endurance without strength means you can paddle foreverâjust really slowly.
Fix: Combine surf endurance training with pulling strength work (rows, pull-ups, band work).
Results Timeline: When Will Your Surfing Cardio Workout Pay Off?
Following a structured surf endurance training program, here's what to expect:
- 2-3 weeks: Reduced shoulder and lat fatigue during sessions
- 4-6 weeks: Noticeably improved paddle endurance and faster recovery between waves
- 8-12 weeks: Significantly longer surf sessions, catching more waves per set, maintaining power throughout session
- 3+ months: Elite-level paddle conditioning, never missing waves due to fatigue
The most common feedback from surfers who prioritize cardio for surfing is simple: "I can finally surf as long as I want."

Beyond Cardio: The Complete Approach to Paddle Endurance
While cardio for surfing is critical, paddle endurance requires a complete approach:
1. Pulling Strength Training
- Build the raw strength that powers each paddle stroke
- Focus on rows, pull-ups, lat pulldowns
- See our surf training program for specific pulling exercises and programming
2. Shoulder Health and Mobility
- Maintain shoulder range of motion and stability
- Include rotator cuff work and scapular exercises
3. Core Stability
- Your core connects upper and lower body during paddling
- Strong core = more efficient force transfer
4. Recovery and Nutrition
- Adequate sleep and nutrition support training adaptations
- Stay hydrated before, during, and after sessions
5. Progressive Overload
- Gradually increase volume, intensity, or complexity
- Track your workouts and make deliberate progress
