<human>:  What types of exercises should I do if I want to bulk up?
<bot>: Resistance exercises such as weightlifting and bodyweight exercises, like push ups and pull ups, are important for building muscle and gaining strength. Doing cardio exercises such as running, biking, and swimming can also help you achieve a more toned physique, as these activities help to burn calories and fat. Other exercises such as yoga, pilates, and stretching can help improve flexibility and improve overall fitness. Additionally, incorporating HIIT (high-intensity interval training) into your workout routine can help you gain lean muscle while still burning fat.
