When to pick Caliber

When to pick NotchFit

What Caliber doesn't do

Caliber is intentionally narrow in two ways: it's strength-led (less variety across cardio, mobility, recovery) and human-paced (changes happen when your coach has time). NotchFit is broader and faster, but you give up the human accountability piece — that's a real tradeoff to weigh.
