The Five Rules for Keeping Fit

Hi, there! I'm Grystal Collins, and I'm very happy to share some time with you. So, you want to keep fit, huh? Well, you surely came to the right place. Together we can keep fit and healthy, and succeed in doing that. It's easy. Everybody can do it, you hear? Just remember the five golden rules.

Number one: Always wear comfortable clothes when you are exercising. You need to feel comfortable and relaxed(放松).

Number two: You should always do some warming-up exercise first to get your body ready for the real thing.

Number three: Never try to do too much exercise too soon. Take it nice and easy now, you hear? There's no rush about this.

Number four: Don't forget to relax for about five minutes when you've finished your exercise. You need to rest a little bit after you've been exercising.
