It's best to take caution and always observe the proper warm up routine before proceeding with your normal bodybuilding exercises. Be sure you execute warm ups properly. It would be best to do two parts of warm up where the first part should be all about cardio exercises. Five minutes in the treadmill could get your blood circulating on all corners of your body but the actual length of warm up varies on the person's age and physical condition. Also, you'd know when you're ready for lifting exercises. Of course, you'd know your condition if you're all pumped up for the heavy weight lifting activities ahead.

The second part of your warm up should consist of psychological convincing. Your body should agree with your mind's goal which means that your workout for today should be better and satisfactory compared to your last performance. Bodybuilding wouldn't be effective anyway if you don't increase the level of what you could achieve for every new bodybuilding session. When you're body is busy warming up the blood for circulation, you can mentally set your goal in mind at the same time.

Doing both parts of your warm up properly and regularly could immensely decrease the risk of getting your muscles torn, leading you to a great bodybuilding experience.
