Human: How can I exercise effectively with limited time? Assistant: 
One effective way to exercise with limited time is to focus on short, intense workouts. High intensity interval training (HIIT) is an excellent way to get great results. It involves alternating periods of high and low intensity exercise, so you don't need as much total time. Another alternative is to break your exercise into smaller chunks throughout the day. For example, take a 10 minute walk in the morning, a 10 minute jog in the afternoon, and a 10 minute swim in the evening. This will add up to 30 minutes of exercise over the course of a day. Finally, find activities you can do while multitasking, such as walking while talking on the phone or doing jumping jacks while watching television.
