Rowing Machine vs Stationary Bike

By the Watta Team · Updated 6 September 2026

The rowing machine and stationary bike are both excellent low-impact cardio options, but they differ significantly in muscle engagement, calorie burn, and training effect. This guide compares both machines across every dimension that matters so you can choose the right one — or learn how to use both effectively.

Muscle Engagement

The rowing machine engages approximately 86% of your muscles — legs, core, back, arms, and shoulders all work together in each stroke. The stationary bike primarily works the lower body — quadriceps, hamstrings, glutes, and calves — with minimal upper-body involvement. If full-body conditioning is your goal, rowing is the clear winner. If you want to isolate leg training (perhaps as a supplement to upper-body strength work), the bike is more appropriate.

Calorie Burn

At equivalent effort levels, rowing burns approximately 10-20% more calories per minute than cycling due to the additional upper-body muscle recruitment. A 30-minute moderate rowing session burns 250-400 calories; the same intensity on a bike burns 200-350 calories. However, calorie burn depends more on intensity and duration than the machine itself. A hard bike session will always beat an easy rowing session.

Joint Impact and Accessibility

Both machines are low-impact, making them suitable for people with joint issues. The bike has a slight advantage for those with lower back pain because the seated posture is more supported. Rowing requires more spinal mobility and can aggravate existing back issues if technique is poor. The bike is simpler to learn — correct cycling form is intuitive, while rowing technique takes 2-4 weeks to develop properly.

Which Should You Choose?

Choose the rowing machine if you want a full-body workout, burn more calories per session, or train for rowing-specific events. Choose the stationary bike if you have lower back concerns, want to isolate leg training, or prefer a simpler movement pattern. The best option is to use both — alternate rowing and cycling days to get the benefits of each while avoiding overuse from either.

Tips

+If you own both machines, row on your strength-focused days (full-body benefit) and bike on your recovery days (legs only, less total fatigue).
+Use heart rate to compare effort between machines — your HR zones are the same regardless of the equipment.
+The Concept2 BikeErg uses the same PM5 monitor as the RowErg, making data comparison straightforward.
+Track sessions on both machines in Watta for a unified training log.
+Start with whichever machine you enjoy more. Consistency matters far more than theoretical calorie differences.

Frequently Asked Questions

Is rowing or cycling better for weight loss?

Rowing has a slight edge for weight loss due to higher calorie burn per minute from full-body muscle engagement. However, the best machine for weight loss is whichever one you will use consistently. Both are highly effective when combined with a moderate calorie deficit.

Can I use a bike if I have bad knees?

Yes, both machines are low-impact and generally knee-friendly. The bike may be slightly easier on the knees because it involves no compression of the knee at deep angles. Adjust the seat height so the knee has a slight bend at the bottom of the pedal stroke to minimise stress.

Is the rowing machine harder than a stationary bike?

Rowing feels more demanding at the same heart rate because it engages more muscle groups. However, both machines can be scaled from very easy to extremely hard. Perceived difficulty depends on intensity, not the machine itself.
