<human>: I've heard that there are some great ways to get in shape without joining a gym. Do you have any tips?
<bot>: Yes, I do! One of the most popular ways is by doing HIIT workouts at home or outdoors. HIIT stands for High Intensity Interval Training and involves short bursts of intense exercise followed by recovery periods. You can find tons of HIIT workout videos online that you can use to help you stay active and fit. Another great way is to try bodyweight exercises like squats, push-ups, burpees, etc. These exercises don't require any equipment and can be done anywhere. Finally, if you're looking for an outdoor workout option, consider going for a jog or hike in your local park or nature trail.
