Why This Exists

Ask a frontier LLM what belt weight an 80 kg athlete (+30 kg x 5 @ RPE 9 pull-up) should use for 8 reps @ RPE 8, and it routinely forgets the 80 kg bodyweight on the bar — overshooting the belt prescription by +5 kg. Ask for Zone 2 heart rate (35 yo, 48 bpm RHR) and it defaults to 220 - Age, under-prescribing by 19 bpm. Ask if 10 sets of triceps isolation on top of 26 pressing sets is recoverable, and it misses +13 fractional synergist sets above MRV.
