Whether you’re a seasoned cyclist looking to sharpen your power output or a complete beginner trying to boost cardio fitness, bike erg workouts offer a low-impact, high-reward solution. And trust me, they’re anything but boring if you know how to structure them.
What Is a Bike Erg, and Why Should You Care?
If you’ve seen those sleek machines in the corner of your gym or watched CrossFit athletes sweating buckets on them, you’ve already met the bike erg. Technically called a Concept2 BikeErg, this machine mimics the resistance and feel of cycling while giving you full control over intensity.
But why choose a bike erg over a traditional spin bike or treadmill?
- It’s easier on your joints, making it perfect for runners recovering from injury.
- You can dial in precise intervals using built-in metrics like wattage, cadence, and heart rate.
- It’s weather-proof. Rain, hail, or 40-degree heat? Doesn’t matter. The bike erg is ready when you are.
I once used a bike erg exclusively during a six-week metatarsal injury recovery. Not only did it keep my cardio base intact, but my FTP (Functional Threshold Power) actually improved!
How Does the Bike Erg Improve Your Performance?
Let’s break this down. The bike erg helps you develop:
- Aerobic Capacity: Long, steady efforts improve your body’s ability to use oxygen efficiently.
- Anaerobic Power: Short, sharp intervals train your body to handle lactic acid buildup.
- Leg Strength & Endurance: Cranking out high-resistance sets makes every pedal stroke stronger.
What’s unique about the bike erg is the accurate feedback. You’re not guessing your effort—you can see it right there on the screen in real time.
Question for You: When’s the last time you finished a workout knowing exactly how many watts you averaged and how that compared to your last session?
5 Bike Erg Workouts to Supercharge Your Fitness
1. The Classic 30-30 Intervals (Anaerobic Power)
This one’s a burner but that’s why it works.
- Warm-up: 10 minutes easy spin
- Main Set: 8 rounds of 30 seconds max effort, 30 seconds easy spin
- Cool-down: 5–10 minutes easy
This workout trains your body to recover quickly between high-intensity efforts. Perfect if you’re preparing for criteriums or short, punchy rides.
Short on time but still want a highly effective workout? Check out these Cycling Tabata Intervals they’re a fast-track to building power and boosting speed in just a few minutes.
2. Pyramid Intervals (VO2 Max Booster)
Warm-up: 10 minutes easy spin
Main Set:
- 1 min hard, 1 min easy
- 2 min hard, 2 min easy
- 3 min hard, 3 min easy
- 2 min hard, 2 min easy
- 1 min hard, 1 min easy
- Cool-down: 5–10 minutes easy
This is great for building VO2 max. Your body’s maximum oxygen consumption rate. It also keeps your mind engaged because you’re always switching it up.
3. Steady-State Endurance (Aerobic Base Building)
- Warm-up: 10 minutes
- Main Set: 45–60 minutes at 60–70% max heart rate or conversational pace
- Cool-down: 5–10 minutes
Boring? Not if you combine it with a good playlist or podcast. This is essential for improving your endurance and burning fat efficiently.
Looking to push beyond your current limits? A structured program like the Cycling Threshold Training Plan can help you steadily improve your power output and endurance over time.
4. Sprint Ladder (High Power Output)
- Warm-up: 10 minutes
Main Set:
- 10-second sprint / 50 seconds rest
- 20-second sprint / 40 seconds rest
- 30-second sprint / 30 seconds rest
- Repeat ladder 2–3 times
- Cool-down: 5–10 minutes
If you want to work on explosive power and sharpen that top-end speed, this one’s for you.
5. FTP Test Simulation (Benchmarking Progress)
Ever wonder how you’re actually progressing? Try this:
- Warm-up: 15 minutes, include 3 x 1-minute hard efforts
- Main Set: 20-minute all-out effort (aim to hold the highest average wattage you can sustain)
- Cool-down: 10–15 minutes
Use your 20-minute average power to estimate your Functional Threshold Power (FTP):
FTP ≈ 20-minute average watts x 0.95
This number is your personal benchmark and helps set training zones for future workouts.
Adding some variety to your bike erg sessions keeps things interesting and challenges new muscle groups. Try incorporating workouts from our cycling intervals for hill climbing guide to simulate those tough uphill efforts, even while indoors.
How to Structure Your Week with Bike Erg Workouts
| Day | Workout Type | Focus | Session Goal | Example Workout |
|---|---|---|---|---|
| Monday | Recovery Ride or Rest | Active Recovery | Flush out soreness and promote recovery | 30 mins at 50–60% Max HR, light effort |
| Tuesday | Interval Training | Speed & Power | Boost anaerobic capacity and explosive power | 8 x 30 sec max effort / 90 sec easy spin |
| Wednesday | Steady-State Ride | Aerobic Endurance | Develop endurance and improve fat metabolism | 60 mins at 60–70% Max HR, steady pace |
| Thursday | Sprint Intervals | VO2 Max & Power | Increase top-end power and improve oxygen uptake | Sprint Ladder: 10s/50s, 20s/40s, 30s/30s, repeat 3x |
| Friday | Rest or Easy Spin | Recovery | Low effort to keep legs loose without fatigue | 30–45 mins at 50–60% Max HR, relaxed pace |
| Saturday | Long Endurance Ride | Fat Utilization & Base Fitness | Build endurance and train aerobic capacity | 90 mins at 65–70% Max HR, include 4 x 5 min tempo efforts |
| Sunday | FTP Test or Tempo Ride | Threshold Training | Assess progress or build sustained power | FTP Test: 20 min max effort OR 3 x 10 min tempo @ 85% Max HR |
If you’re also running or lifting, adjust accordingly.
You can also stack your harder workouts on days you’re already doing strength training. This keeps recovery days truly restful.

How to Calculate and Use Your FTP on the Bike Erg
If you’re serious about making progress with your bike erg workouts, knowing your Functional Threshold Power (FTP) is a game-changer. Think of FTP as the maximum power you can sustain for one hour. This number helps you train smarter, not harder, by setting precise intensity zones for every workout.
Most riders perform a 20-minute all-out test to estimate FTP. It’s toughbut incredibly effective. After the test, multiply your 20-minute average wattage by 0.95 to estimate your true FTP.
Example:
- 20-minute average power = 210 watts
- Estimated FTP = 210 x 0.95 = 199.5 watts (round to 200 watts)
Once you have your FTP, use it to structure your workouts like a pro.
If you’re unsure how to convert your new FTP number into real-world pacing, try using this handy cycling pacing calculator. It takes the guesswork out of structuring your workouts and ensures you’re always training in the correct zone.
| Zone | % of FTP | Training Purpose |
|---|---|---|
| Zone 1 | Less than 55% | Active Recovery – Easy spins to promote recovery |
| Zone 2 | 56–75% | Endurance – Build aerobic base and fat metabolism |
| Zone 3 | 76–90% | Tempo – Improve muscular endurance and stamina |
| Zone 4 | 91–105% | Threshold – Boost sustainable race pace and FTP |
| Zone 5 | 106–120% | VO2 Max – Improve high-intensity capacity |
| Zone 6 | 121%+ | Anaerobic – Short sprints and explosive power |
Using these zones ensures every workout has a clear purpose. You’ll avoid wasting time in that “gray zone” where you’re working hard but not making specific improvements.
Re-test your FTP every 6–8 weeks to measure progress and adjust your training zones. Trust me, few things feel better than seeing those numbers climb!
