<human>:  I want to start exercising, but I don't know where to begin. What type of exercises should I do and how often?
<bot>: You should start with exercises that are tailored to your fitness level to ensure you don't overdo it and cause an injury. A good place to start is with basic cardio such as walking or jogging for a minimum of 30 minutes 3-4 times a week. Additionally, you can incorporate weight and strength training 2-3 times a week, focusing on major muscle groups. Lastly, flexibility exercises such as yoga or Pilates, should be done once or twice a week. Doing this combination of exercises will help you see results quickly and stay motivated to continue.
