A 30-minute kettlebell workout routine that you can do 4 days a week is a great way to build strength, improve endurance, and increase overall fitness. This is a balanced routine focusing on different muscle groups each day to ensure full-body conditioning. Make sure to use a kettlebell weight that challenges you while allowing you to maintain proper form. Tips: -Form: Focus on maintaining proper form to prevent injuries. -Rest: If needed, take longer rest periods between circuits. -Hydrate: Drink water before, during, and after your workout. -Progression: As you become more comfortable, increase the kettlebell weight or add more rounds.
