WattCycling vs Spinning: What's the Difference?
Both are great indoor cycling workouts. But they're built around different purposes, and knowing the difference helps you choose what's right for your goals.
If you've ever wondered whether WattCycling and spinning are the same thing, you're not alone. They both involve a stationary bike and a lot of sweating. But they're built around different ideas of what a bike session is actually for.
Spinning: Training on the Bike
In a spinning class, the bike is the vehicle. The goal is a great workout — high energy, music, and a coach driving the room through effort. The instructor tells you to turn up the resistance, sprint, climb, recover. It's accessible, social, and genuinely fun.
Spinning doesn't require you to know anything about power, zones, or cycling mechanics. You show up, follow the cues, and leave having worked hard. That's a completely legitimate reason to train.
WattCycling: Training the Bike
WattCycling flips the frame. The bike becomes the subject, not the vehicle. Sessions are built around watts — actual power output measured in real time — and each rider has their own personal zones calculated from a short test.
"Spinning tells you to push harder. WattCycling shows you how hard you're actually pushing."
That difference matters if your goal is to improve specific physiological qualities — aerobic capacity, threshold power, recovery between efforts. Because everyone's zones are individual, a room full of riders at very different fitness levels can train together and each one is working at exactly the right intensity for them.
Different Purposes, Both Valid
Neither format is better. They answer different questions.
Spinning answers: How hard can I push today?
WattCycling answers: How am I improving over time?
If you want an energetic group session that leaves you feeling worked, spinning delivers that well. If you want structured progression — to see your zone 2 power go up over six weeks, to build a specific aerobic base, or to complement a sport like HYROX with low-impact conditioning — WattCycling gives you the data to do that.
Some people do both. There's no reason not to.
Who Trains with WattCycling
The people who get the most out of WattCycling sessions at Lead Out tend to fall into a few groups.
Cyclists and triathletes are our first and main audience. If cycling performance is something you're actively trying to improve — whether for races, sportives, or just getting stronger on the bike — training with power zones is the most direct way to do it. You can target specific weaknesses, build threshold capacity, and track real progress over a season.
Anyone building endurance and leg power from scratch or wanting to take it further. The watt-based structure makes it easy to progress deliberately rather than just grinding out sessions and hoping for improvement.
Hybrid athletes — especially those training for HYROX or other sports that mix running and strength — often use WattCycling specifically because it builds aerobic capacity and leg power without adding more running load to already heavy legs. It's high-output, low-impact, and easy to slot in alongside other training.
At Lead Out
Our WattCycling sessions are structured around your personal zones from day one. If you've never done it before, the first step is a short test to establish your baseline. From there, every session has a clear purpose.
Come in for a taster session if you're curious. It won't feel like a sales pitch — you'll understand the difference from the first interval.
