We do love a protocol in the fitness world, don’t we? Norwegian 4x4 intervals. Zone 2. Sprint intervals. Tempo runs. Threshold work. Every few months there’s another method promising to build a bigger engine, improve VO2 max and slow your resting heart rate to a crawl.

Though variety is indeed the spice of life, the truth is that most genuinely effective conditioning methods share just a handful of common traits: consistency, progressive overload and just enough discomfort to force adaptation without killing you off for the rest of the week.

One of the simplest (but most brutally effective) examples of this is ‘Mikko’s Triangle’.

Popularised by Finnish CrossFit legend Mikko Salo, the workout has become something of a benchmark test of aerobic fitness inside the functional fitness world. Salo, who won the 2009 CrossFit Games, built a reputation for brutally simple training sessions executed with frightening consistency and pacing discipline. Mikko’s Triangle is very much cut from that cloth.

The protocol itself is straightforward:

40-Minute EMOM (Every Minute on the Minute)

Repeat for 10 rounds

What to read next

Minute 1: Row

Minute 2: Bike

Minute 3: SkiErg

Minute 4: Rest

The trick is choosing a calorie target for each movements and holding it consistently for the entire workout. Strong athletes might aim for 18-20+ calories per minute across all three machines. Mere mortals should start considerably lower.

And take it from me – lower is wiser for your first outing.

The first few rounds (should) feel more than manageable. Then somewhere around the halfway point your lungs start to struggle, your transitions start to become sluggish and the SkiErg feels like it has a personal vendetta against you.

That’s the beauty of the protocol. Because the workload rotates between different movement patterns – upper-body dominant skiing, cyclical rowing and leg-heavy biking – you can sustain a much higher overall cardiovascular output than you could on a single machine alone. The heart and lungs become the limiting factor, not just local muscular fatigue.

If you’re tackling Mikko’s Triangle for the first time, we'd suggest you leave your ego in the changing room. Spend your opening session establishing sustainable numbers rather than trying to impress the gym.

Your goal should be finishing every working minute with roughly 5-10 seconds left to transition and recover.

As your fitness improves, gradually increase calories while ensuring you can still maintain consistency across all rounds. The magic here isn’t found in smashing a few epic rounds, it’s in not falling apart in rounds eight, nine and ten.

All told, Mikko's Triangle is simple, brutal, and effective. The trifecta for conditioning work that's actually worth doing.
