Gasping for Air: Why Your Cardiovascular Fitness Hit a Brick Wall
You used to ride 30-minute motos without breaking a sweat. Now you're sucking wind after the first few laps. Here's what's happening to your cardiovascular system and how to get your wind back.
The Cardiovascular Reality Check
Motocross might look like a strength sport to outsiders, but every serious rider knows the truth: it's one of the most cardiovascularly demanding activities on the planet. Your heart rate stays elevated at 85-95% of maximum throughout entire motos, with brief spikes to 100% during starts, jumps, and intense battle sections.
The problem? After 35, your cardiovascular system starts betraying you just when you need it most.
The Science of Cardiovascular Decline
Your Maximum Heart Rate Drops
The old formula of 220 minus your age isn't perfect, but it illustrates the reality: your maximum heart rate decreases by about 1 beat per minute per year. At 35, you've already lost 10-15 beats per minute compared to your early twenties. This means your cardiovascular ceiling is literally getting lower every year.
VO2 Max Takes a Nosedive
VO2 max – your body's ability to consume and utilize oxygen – declines by approximately 10% per decade after age 30. But here's the brutal part: it declines faster if you're not consistently training. Some sedentary adults see drops of 15-20% per decade.
For motocross riders, this translates directly to feeling out of breath sooner, recovering slower between motos, and fading dramatically in the second half of long practices.
Cardiac Output Decreases
Your heart becomes less efficient at pumping blood with age. Stroke volume (amount of blood pumped per heartbeat) decreases, and your heart rate response becomes sluggish. The result? Less oxygen-rich blood reaching your working muscles when you need it most.
Arterial Stiffness Increases
Your blood vessels become less elastic over time, creating more resistance to blood flow. This means your heart has to work harder to deliver the same amount of oxygen to your muscles. It's like trying to drink a thick milkshake through a narrow straw.
The Real-World Impact on Your Riding
The Dreaded Fade
You know the feeling: you start strong, hit your lines perfectly for the first 10 minutes, then gradually feel like you're riding underwater. Your lap times slow, your technique deteriorates, and simple mistakes multiply as oxygen debt accumulates.
Recovery Between Motos Becomes Impossible
Remember when 15-20 minutes between motos was plenty time to catch your breath? Now you're still gasping while the gate drops for the next race. Your heart rate stays elevated longer, and you never fully recover between sessions.
Mental Fog and Poor Decision Making
When your brain isn't getting enough oxygen, cognitive function suffers. You make poor line choices, miss braking points, and react slower to changing track conditions. What feels like "losing your edge" is often just inadequate cardiovascular fitness.
The Vicious Cycle of Fatigue
Poor cardiovascular fitness leads to early fatigue, which leads to poor riding technique, which leads to working harder to maintain the same pace, which leads to even more fatigue. It's a downward spiral that many riders never escape.
Why Traditional Cardio Training Fails Motocross Riders
The Intensity Problem
Most cardio training happens at moderate intensities (60-75% heart rate max). Motocross happens at high intensities (85-95% heart rate max). Training at moderate intensities won't prepare you for the demands of racing.
The Duration Mismatch
Long, steady-state cardio sessions don't prepare you for the intermittent high-intensity demands of motocross. You need to train your body to maintain high intensities for 30-40 minutes, not cruise at moderate intensities for hours.
The Specificity Gap
Running, cycling, and other traditional cardio activities don't recruit the same muscle groups or movement patterns as motocross. You can be a decent runner and still get smoked on the bike because the cardiovascular demands are completely different.
The Twin Halos Cardiovascular Revolution
1. Motocross-Specific Heart Rate Training
Train in the zones that matter for motocross:
Zone 4 (85-95% max heart rate): This is your bread and butter. Most of your riding happens here.
6-8 minute intervals at this intensity
2-3 minute recovery between intervals
3-4 intervals per session, 2x per week
Zone 5 (95-100% max heart rate): For starts, passing, and those oh-shit moments.
30-90 second intervals at max effort
2-3 minute recovery between intervals
6-8 intervals per session, 1x per week
2. The Polarized Training Approach
80% of your cardiovascular training should be easy (Zone 1-2), 20% should be very hard (Zone 4-5). This maximizes adaptation while allowing proper recovery.
Easy Days (Zone 1-2):
30-60 minutes at conversational pace
Should feel almost too easy
Builds aerobic base and enhances recovery
Hard Days (Zone 4-5):
High-intensity intervals as described above
Should feel extremely challenging
Builds the specific fitness you need for racing
3. Sport-Specific Training Methods
Bike Trainer Sessions: Use a mountain bike or stationary bike to mimic the position and muscle recruitment patterns of motocross:
30-40 minute sessions alternating between standing and sitting
Include 2-3 minute high-intensity efforts every 5-6 minutes
Focus on maintaining upper body tension while pedaling
Battle Rope Intervals: Incredible for building the specific cardiovascular fitness needed for motocross:
30 seconds all-out effort, 90 seconds rest
Repeat 8-12 times
Mimics the intermittent high-intensity demands of riding
Burpee Ladder Workouts: Build full-body cardiovascular fitness:
Minute 1: 1 burpee, rest remainder of minute
Minute 2: 2 burpees, rest remainder of minute
Continue up to 10-15 burpees, then work back down
4. Recovery and Adaptation Strategies
Active Recovery:
Easy 20-30 minute walks or bike rides
Promotes blood flow and waste removal
Enhances adaptation without adding stress
Heart Rate Variability Monitoring: Track your nervous system recovery:
Use HRV apps to monitor readiness to train
Adjust training intensity based on HRV scores
Avoid high-intensity work when HRV is suppressed
5. Breathing Pattern Training
Efficient breathing can dramatically improve cardiovascular performance:
Diaphragmatic Breathing:
10 minutes daily of deep belly breathing
Improves oxygen efficiency and reduces anxiety
Practice during easy riding to groove the pattern
Box Breathing for Race Prep:
4 counts in, 4 counts hold, 4 counts out, 4 counts hold
Calms the nervous system before motos
Helps maintain composure during intense racing
The Mental Component of Cardiovascular Fitness
Confidence in your fitness allows you to ride more aggressively early in motos when track conditions are best. Knowing you won't fade gives you a massive mental advantage over competitors who are already worried about running out of gas.
Visualization training can help improve cardiovascular efficiency. Spend time visualizing yourself riding strong throughout entire motos, maintaining perfect technique even when fatigued.
Common Cardiovascular Training Mistakes
Mistake #1: Only Training in the "Gray Zone"
Most riders train too hard on easy days and too easy on hard days. This leads to chronic fatigue without proper adaptation.
Mistake #2: Ignoring Recovery Between Sessions
Cardiovascular adaptations happen during recovery, not during training. Pushing too hard too often leads to overtraining and diminished performance.
Mistake #3: Thinking More is Always Better
Quality trumps quantity for motocross-specific fitness. Smart, targeted training beats high-volume junk miles every time.
Mistake #4: Neglecting Nutrition for Performance
Your cardiovascular system needs proper fuel to adapt and perform. Inadequate carbohydrate intake severely limits high-intensity training capacity.

The Cardiovascular Truth
Your cardiovascular system will never be as naturally gifted as it was at 25. But here's what most riders miss: with smart training, you can actually develop better race-specific fitness than you had in your youth.
The key is training smarter, not just harder. Focus on the intensities and durations that matter for motocross, allow adequate recovery, and be patient with the adaptation process.
The riders who figure this out are the ones still pulling holeshots and leading motos well into their 40s and beyond. They're not trying to turn back the clock – they're maximizing what they have right now.
Ready to get your wind back? Twin Halos' cardiovascular programs are designed specifically for the unique demands of motocross and the realities of training over 35. Because running out of gas is a choice, not an inevitability.
Stop making excuses for poor fitness. Your competition isn't waiting for you to get in shape – they're already there.
