Steady, low impact, high return.
These workouts are all about Low Intensity Steady State cardio (LISS) done in Zone 2, the sweet spot where your heart rate stays moderate and your body becomes a fat-burning, endurance-building machine. Think incline walking, slow jogging, cycling, or rowing at a pace where you can still carry on a conversation.
Why it matters
Zone 2 training builds your aerobic base, improves cardiovascular health, helps your body recover better, and burns fat efficiently. It’s a critical foundation that makes your harder workouts even more effective.
How often
Aim for 3 to 4 sessions per week, 30 to 45 minutes each.
How to calculate your Zone 2 heart rate
Use this simple formula to find your estimated Zone 2 range:
(220 - your age) x 0.6 = bottom of Zone 2
(220 - your age) x 0.7 = top of Zone 2
For example, if you’re 40 years old:
(220 - 40) x 0.6 = 108 bpm
(220 - 40) x 0.7 = 126 bpm
So for a 40-year-old, Zone 2 would be roughly 108 to 126 beats per minute.
