How Hard Should Day 20 Feel?

Aim for a moderate effort.

Your breathing and heart rate should increase, but you should still feel in control.

The talk test can help you judge your effort.

If you're able to speak in short sentences but are breathing more heavily than normal, you're generally working at a manageable moderate intensity.

If you cannot speak comfortably, slow down or rest.

Fitness improves through consistent, manageable effort—not through constant exhaustion.
