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.
Store scaled accuracy minus unscaled accuracy on the test part (both with n_neighbors=5), rounded to 3 decimals, in result. Scaling usually helps KNN, but not always: when the column with the biggest numbers is also the most useful one, scaling can hurt. Always check instead of assuming.
