Q: i ride my stationary bike for an hour and then do weight training. is that good?

A: Certainly, that's perfectly fine. If you do heavy weight training (12 reps or fewer per set before muscular failure sets in), then all other things being equal I would recommend doing weight training separately from cardio or at least do weights before cardio. However if your schedule doesn't allow that or if you simply prefer to do cardio first, then that's fine too -- you'll still get very good results.

You didn't specify what kind of weight training you do, so in case you'd like some suggestions on weight training, please read my Weight Training article. Similarly, if you'd like some ideas on improving your diets, make sure to check out my Diet article.
