);

-- Also fix exercises table if it exists
DROP TABLE IF EXISTS exercises;
CREATE TABLE exercises (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    training_id INTEGER NOT NULL,
    name VARCHAR(255) NOT NULL,
    splitted_weight BOOLEAN DEFAULT 0,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    FOREIGN KEY (training_id) REFERENCES trainings(id) ON DELETE CASCADE
);

-- Fix approaches table if it exists
DROP TABLE IF EXISTS approaches;
CREATE TABLE approaches (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
