Go Slower, Get Fitter!

…Just Press Play Above!

Zone 2 training is having a major moment right now, and you’ve probably heard the buzz. But, this “new” idea has been around for decades.
​
Back in the early 1980s, we called it “long slow distance.” It’s also been called aerobic base training and endurance training…and now it’s Zone 2 training.
​
Think of your heart rate as a dial with five settings:

Zone 1 is an easy, recovery-level effort.
Zone 2 is a steady, sustainable pace where you can still carry on a conversation (but you might not want to!)
Zone 3 pushes into that aerobic sweet spot, where your endurance builds and your body learns to sustain effort over time.
Zone 4 is where things get uncomfortable. You’re working hard, your speed is climbing, and your body is learning to handle the burn.
Zone 5 is flat-out maximum effort, go for broke!
​
Every zone has a job to do, and your body responds differently to each one. The real question isn’t which zone is best… it’s how much time you should be spending in each?

The Perfect Mix

The research points to an 80/20 split as the sweet spot. Eighty percent of your cardio time in Zone 2, twenty percent in Zone 5. That means aiming for 3 to 4 hours of Zone 2 per week, broken into sessions of 45 to 60 minutes.

For Zone 5, just 1 to 2 sessions per week does the job. A popular method involves 4 minutes of all-out effort followed by 4 minutes of easy recovery, repeated 4 to 6 times.

You don’t have to choose between the two. You need both, in the right proportion.

Why Zone 2 Works

What makes Zone 2 so valuable, especially as we get older, comes down to what’s happening at the cellular level. Zone 2 improves mitochondrial function, metabolic flexibility, and long-term endurance capacity. Your mitochondria are your cells’ power generators, and Zone 2 training makes them more numerous and more efficient. That translates to better fat burning, steadier energy throughout the day, and a body that manages fuel more effectively over the long haul.

Why Zone 5 Matters Too

Your high-intensity intervals build something Zone 2 can’t do alone: peak aerobic capacity, or VO2 max. Research shows that VO2 max is one of the strongest predictors of longevity, strongly correlated with a reduction in all-cause mortality. Those short, hard efforts push your cardiovascular system to its ceiling, and over time, they raise that ceiling considerably. The discomfort is temporary. The adaptation is lasting.

A Blast From the Past

Today’s free zone 2 workout is a blast from the past…. Fat Burning Workout from 1988. It’s the original long and slow workout, a 60-minute classic designed to keep your effort steady, stay in that fat-burning zone, and let your body do the rest. You’ll start with a low-impact warm-up that gradually raises your heart rate, move into cardio that keeps you moving at a comfortable, sustainable pace, then shift into a body shaping segment that targets and tones your abs, glutes, and thighs… click play on the video above!
