Rowing Machine vs Exercise Bike: Which is Better?

I've owned both. Currently I use a Concept2 rower 3x weekly. Previously I had a spin bike I used maybe twice a month.

The rower works for me because I actually enjoy it. The bike felt like a chore. That difference matters more than any spec comparison.

Here's how to figure out which suits you.

## Quick Comparison

## The Muscle Question

This is the biggest difference.

Rowing: Full-body workout. Legs drive (60%), back pulls (20%), arms finish (20%). Core stabilises throughout. You're building muscle while doing cardio.

Bike: Lower body only. Quads, hamstrings, glutes, calves. Core does almost nothing unless you stand.

If you're already strength training, this might not matter—you're getting muscle work elsewhere. If cardio is your main exercise, rowing gives you more bang per minute.

## Calories and Fat Loss

At moderate effort for 30 minutes: - Rowing: 250-350 calories - Cycling: 200-300 calories

The difference sounds significant but isn't really. Work harder on either and you burn more. The machine you use 5x weekly beats the "better" one you use twice.

My view: Don't choose based on calorie burn. Choose based on which you'll actually do.

## Space Reality

### Rowing Machine

In use: 2-2.5m length. You need clearance behind you on the pull.

Stored: Depends on model: - Concept2 RowErg: Folds upright, ~0.6m x 1.3m footprint - Dripex Magnetic: Folds to ~0.5m x 0.3m standing

### Exercise Bike

Footprint: ~1.2m x 0.5m. Doesn't fold, but smaller overall. Transport wheels let you roll it against a wall.

Winner: Bikes for tight spaces. But foldable rowers work if you have somewhere to store them.

## Noise: Flat Compatibility

If you have neighbours below: magnetic everything. Air rowers and chain-driven bikes are too loud for early mornings.

## The Technique Question

Bikes: Zero learning curve. Everyone knows how to pedal. Sit down, start spinning.

Rowing: Proper technique takes practice. Bad form leads to back strain.

The sequence matters: legs push, back opens, arms pull. Not: yank with your arms while your legs flail. Watch a YouTube tutorial before your first session.

Is this a dealbreaker? No. Technique takes maybe 20 minutes to learn properly. But it's a real consideration if you want instant gratification.

## Joint Considerations

Both are low-impact compared to running.

Rowing: Zero impact. You're seated, sliding on a rail. Good for people with ankle, knee, or hip issues.

Biking: Near-zero impact. Can aggravate knee problems if seat height is wrong. Adjust properly.

For injury recovery or joint problems: Both are gentler options. Neither is clearly better.

## The Decision Framework

### Choose a Rower If:

- Full-body workout matters - You want strength and cardio together - You're willing to learn technique - You have 2m+ clear space (or storage for folded) - You find cycling boring (many do)

### Choose a Bike If:

- You want zero-learning, sit-and-go cardio - Space is limited - You have lower back issues (upright position is easier) - You'll use Zwift, Peloton, or similar apps - Cycling feels natural to you

## Top Picks

### Rowers

The Concept2 is the gold standard—used in every CrossFit box and rowing club. The Dripex is 75% of the experience for 25% of the price.

### Bikes

Both JLL bikes are quiet, compact, and reliable. The IC300 has heavier flywheel for smoother feel.

## The Honest Answer

The best cardio equipment is the one you'll use.

I've seen expensive Concept2s become clothes hangers. I've seen cheap bikes used daily for years.

If you can, try both at a gym before buying. Many people have strong preferences they didn't expect. A £250 Dripex you row 4x weekly beats a £1,000 Concept2 gathering dust.
