How You Can Manage Working Out Twice a Day

One of my favorite things to do is to work out in the morning and afternoon or evening. I find often due to my schedule that a tough workout needs to be split into two different workouts in the same day.

Here is the question: 

"I would like to know if when I work out in the morning at home, on the days I work out, could I do some more workout routines at the office? By doing more exercises at the office after my initial workout, does this hamper the rebuilding of the torn muscle fibers that occur from the first workout? Do my muscles need all the time they can get to recover from each workout? Any info would be greatly appreciated!"

I have found over the years, this type of split routine works well to burn additional calories in the day and help speed up the metabolism in the evening when it naturally tends to slow down. There are some rules to the two-a-day workout, however:

1. Recovery is important

You have to be creative if you do a two-a-day routine. You either should split your cardio exercise from your weights or PT exercises, or do a combination of cardio/stretching and PT in the morning and weights in the evening. If you do exercises like push-ups and bench presses in the same day, either do them together in the same workout or be careful not to do morning push-ups and evening bench presses for too many weeks in succession.

Once a week, it is OK to push your body this way and basically do two chest workouts in the same day, but take at least two days off from repeating those exercises again. And do your pushups in the morning and bench in the evening since bench-press weights will be more stressful on your muscle fibers if lifting heavy weights. You are right; you need to recover.

2. Leg PT is different

I would do leg workouts only once a day, though I would not count a run or bike not as a leg workout but as a cardio workout. So on leg days, I like to do the PT or weights first, then work out the lactic acid produced by a jog, bike or elliptical glide later in the day if you must split the workouts in two.

3. Morning workout meal

If you are doing cardio in the morning, it is important to drink water before exercise. If you are lifting weights, doing challenging PT or pushing the speed of your run and doing intervals or speed workouts, you may want to have fruit or a sport drink before running, just to boost your glycogen levels. In high-intensity workouts, you may feel dizzy, nauseated or weak when you run low on your immediate energy source -- glycogen. After your morning workout, replenish your glycogen levels with fruits like bananas, strawberries, apples, etc. Also protein should be consumed in the post-workout meal to help rebuild the muscles and speed recovery.

Here are a few examples of workouts that can be split during the day:
