Every AI coach I tried was a generic chatbot agreeing with everything I typed. Powerup Packs installs an expert instead. One sentence, a short onboarding, and Muse becomes a marathon coach, a macro coach, a prayer keeper who actually knows you. Eleven experts, $19 each, yours forever. And they share notes. My training log feeds Macro Chef every morning, so the nutrition expert builds on what the training expert did. Train and Fuel, one system, zero re-explaining.
