<human>:  I am looking for a new hobby - what kind of exercise would you recommend for me?
<bot>: I would recommend starting with a low impact exercise such as walking or cycling, as these are great for getting started and help to build up strength and endurance. Swimming and hot yoga are also great options, depending on your preference. Aerobic and HIIT classes are becoming increasingly popular and are a great way to get your heart rate up and get moving. Whatever you choose, make sure to mix it up in order to keep it interesting and challenging.
