[speaker001:] I think Yoga might be suitable for me.
[speaker002:] Why?
[speaker001:] Because it doesn't require a lot of energy and thus easy to keep up.
[speaker002:] But I see people sweat a lot doing Yoga too.
[speaker001:] I don't know. I just need to try it once. I'm in urgent need of some exercise to lose some weight.
[speaker002:] You should try swimming then. It helps you to keep fit.
