Math so simple you don't even need a calculator!

Knowing your max heart rate is important for determining which heart rate zone you are in while exercising.

💚 Zones 1 & 2: 50%-70% of max heart rate
💛 Zone 3: 70%-80% of max heart rate
🧡 Zone 4: 80%-90% of max heart rate
❤️ Zone 5: 90%-100% of max heart rate

Assuming you should spend the whole workout in the red? Think again.

You should transition through all zones during a workout, with most of your time in Zones 2-3 to burn calories and build endurance without burnout.

Tracking your heart rate during a workout tells you whether you're actually pushing hard enough, or pushing too hard to recover properly. This is the science of heart rate training.

This month, we're breaking down why heart rate training is so important. Stay tuned for more!

Working out for an hour doesn't cancel out sitting for eight.

Harsh? Maybe. True? The research says yes.

Small breaks add up more than most people realize. A two-minute walk. Standing during a call. Taking the stairs.

Consistency beats complexity every time.
