Quickstart

from client import PersonalAgentZone2CardiorespiratoryFitness

agent = PersonalAgentZone2CardiorespiratoryFitness()
res = agent.calculate_zone2_metabolic_corridor(age=38.0, resting_hr=54.0)
print(f"Zone 2: {res['zone2_corridor_bpm']['lower_bound_60pct_hrr']} - {res['zone2_corridor_bpm']['upper_bound_70pct_hrr']} bpm | VO2max: {res['estimated_vo2_max_ml_kg_min']}")
