Q:  Can I do more work on a muscle group later in the evening, after having worked on it in the morning?  I hear that some people do that. What is the benefit and how should I work out the second time?

A:  Generally, people will tell you that you shouldn’t do it, but there are some pros who have actually done it with good results, and it’s usually to get in shape fast. Levrone used to do it and people would marvel at how rapidly he got into shape. Recovery is important, but sometimes it’s beneficial to work the lactic acid out from a hard and heavy intense workout from earlier in the day, with some lighter, higher rep work.  This isn’t something to make a habit of, however, because you need to give your muscles a good workout and then leave them alone to repair and recover. But it really depends on what you’re trying to accomplish.  You can also do it where you hit some exercises in the morning and if you didn’t finish, you can go hit some more in the evening. Typically, it’s splitting up body parts – chest in the morning and triceps at night, and so on. If it’s just simple boredom, buy a book!
