Benefits of Indoor Cycling HIIT Workouts

High-intensity-interval training (HIIT) is a training method that alternates short bursts of near-maximum effort with rest periods. Applying this method to cycling helps increase your endurance and power on the bike.

Plus, it's a good option if you're looking to avoid the high impact that often comes with other HIIT workouts. "When you take HIIT to a bike, you reap the same benefits without the added stress of impact on your body's joints, making HIIT cycling workouts well suited for a person of any age," says Lauren "Lolo" Wilson, senior master instructor for CycleBar.

Other benefits include improved oxygen consumption and aerobic capacity, increased calorie burn in a short amount of time and an increase in the effect of EPOC or excess post-exercise oxygen consumption, which helps to burn calories even after you're done working out.

Tips for Your Best Indoor Cycling HIIT Workout

Before you get in the saddle, there are some basic guidelines that apply to all fitness levels. These tips will also help you stay motivated as your cycling workouts take off.

Go Easy in the Beginning. Whether you're new to exercise or you're coming back from a fitness hiatus, the best thing you can do is ease into exercise. HIIT workouts are very demanding, so it's important to start out slowly, says Booth.

Think Quality Over Quantity. "Ideally, you should start with one or two HIIT cycling workouts per week that are 30 to 45 minutes in length," Wilson says. When you feel ready to add more, the next step is to strive for consistency. After three to four weeks, Wilson recommends increasing your sessions to two to four times a week for 45 to 60 minutes each.

Don't Skip the Warm-Up. As tempting as it may be to jump right in with the intense work intervals, allowing enough time to warm up will make a difference in the quality of your workout. Aim for a thorough warm-up of about 10 before you build into the intensity of the intervals, Booth says.

Focus on Intensity. To gain the benefits of a HIIT cycling workout, it's crucial to perform the intervals at a very high intensity, Booth says. Which also means it's essential to allow for full recovery between sessions and never perform workouts on consecutive days.

2 Indoor HIIT Cycling Workouts to Try

Clipping in and pedaling is the easy part. Knowing what to do once you break a sweat is where it can become challenging. That's why having a plan before getting in the saddle is so important. Below, Booth shares a calorie-torching indoor cycling HIIT workout.

25-Minute Indoor Cycling HIIT Workout for Beginners

For this workout, you'll be increasing both speed and resistance, so you may need to experiment with both until you find what you can sustain for one minute that's challenging but doable.

Exactly how much you increase the resistance and leg speed (RPM) depends on your fitness level. To begin with, consider increasing the resistance anywhere from two to five levels. Your leg speed can jump up by 10 to 20 RPM, but on average, your RPM will range from 60 to 90, depending on the resistance and interval.

  1. Warm up with easy pedaling, gradually increasing your heart rate for five minutes. You should be able to talk, but also begin to feel the intensity increase and your body heat up.
  2. After the warm-up, increase both resistance and speed (RPM) and push as hard as possible for one minute.
  3. Recover for two minutes.
  4. Repeat five times total.
  5. Cool down with five minutes of easy pedaling.

25-Minute Speedy HIIT Workout on the Bike

This workout focuses on speed. For these 30-second sprint intervals, you may want to take the RPM over 100. That said, 110 to 120 is often the upper limit for RPM, so if you find yourself approaching that, dial up the resistance a bit. Exact resistance levels and RPM will vary based on the bike you're riding.

  1. Warm up with easy pedaling, gradually increasing your heart rate for 10 minutes. You should be able to talk, but also begin to feel the intensity increase and your body heat up.
  2. After the warm-up, increase resistance slightly and go for all-out effort on RPM for 30 seconds.
  3. Take off some resistance and pedal easy for 30 seconds.
  4. Repeat this interval 10 times.
  5. Cool down with five minutes of easy pedaling.
