Same search as before (odd K from 1 to 25, scaled pipeline, cv=5 on the training part of the usual split). Store the best average cross-validated accuracy, rounded to 3 decimals, in result.
Use the inputs age, weight_kg, resting_heart_rate and weekly_sessions, the answer programme, and train_test_split with test_size=0.25, random_state=42 and stratify on the answer.
