I’ve seen every excuse in the book, including “I missed my optimal window for training so I skipped today’s workout.” Don’t let this happen. Unless you’re injured, sick, or overtrained, exercising is better than not exercising. Schedule your workout when you have the best chance of getting it done.

2. When you FEEL the best.

There are times during the day when you will have a slight physiological advantage if you work out during them, but none of those trump the psychological edge you have if you feel like exercising. As simple as this sounds, effort equals results more than any other one factor. This means that if you’re a night owl, work out at night. Morning person? Work out first thing in the morning…you get my drift.

3. When your glycogen stores are full.

Glycogen is mainly recharged by carbohydratesCarbs: A Love Story. Read more ... », and is extinguished very quickly with exercise, brain activity, and most other tasks. This means it fluctuates throughout the day and is always highest immediately after you digest a meal containing carbohydrates. This means—depending on your eating schedule—your body is probably primed for peak exercise in the late morning, afternoon, or early evening.

At night, your body can store glycogen, meaning that it’s possible to wake up and train in the morning before you’ve eaten and still have enough energy3 Day Refresh and Shakeology: Break Bad Habits. See Success.. Read more ... » to get through a workout, but this is a theoretical scenario. Most of us, especially when we’re training hard and not eating a ton, will burn through glycogen recovering from the prior day’s activities. The result is that those early morning workouts can lead to something called “the bonk,” which is what happens when your body runs out of glycogen. Essentially you lose the ability to push your anaerobic realm, and you feel like you’ve hit a wall.

Bonking is not one of those “good pain” times. When your body is out of glycogen, it starts to break down muscle tissue and you quickly begin to offset the fitness gains you’ve made. It’s inevitable that it will happen to you at some point. When it does, don’t try and push through. Instead cut your losses and get on the recovery program by eating, resting, and then reevaluating your eating schedule and/or choice of workout times.

If exercising when your glycogen stores are low is the only time of day available, you can fix the situation nutritionally.

4. In the morning on an empty stomach.

You’re also “burning fat,” which sounds even cooler (although it’s not nearly as effective as “burning glycogen” when it comes to losing body fatHow to Reduce Body Fat Percentage. Read more ... »). While fantastic, in theory, it’s not if you force your body into a situation where you bonk.

You won’t bonk, however, unless you’re training anaerobically (in other words, hard—as in your heart rate is pegged during parts of the workout). This means easy workouts can have added benefits if done in the morning on an empty stomach. This is why during programs like P90X Doubles, the easier workout of the day is scheduled in the morning.

5. At night before bed.

This time of day is last for a reason. Unless it is really the only time you will work out or the only time you feel the best, you should probably avoid it.

Working out directly before bed can affect your sleep. Most people have a hard time getting to sleep after a workout because exercise can throw off your melatonin, the hormone that regulates sleep, among other things. This isn’t ideal because sleep is very important for recovery. It’s when your body naturally produces most of its own performance-enhancing drugs in the form of hormones. Anything that hurts your ability to sleep should be eliminated if possible.

Exercise also utilizes a lot of nutrients3 Day Refresh and Shakeology: Break Bad Habits. See Success.. Read more ... », which are further depleted at night.

If you’re on a low-calorie diet and plan to train hard at night, you should follow your workout with, at least, a nutritional recovery strategy (Results and Recovery Formula or equivalent), if not a small meal before going to sleep.

Couple SleepingI’m not the norm, so I’ll play the counterpoint to my point as I can fall asleep (and often sleep much better) immediately after a very hard workout. If you’re like me, there’s nothing wrong with training at night. Just follow nutritional protocols that don’t leave you depleted and starving when you wake up. I’ve done this and it can be so severe that you wake up in the middle of the night, a common issue with bodybuilders and fitness trainers getting ready for competition. This is not ideal as it means your body is essentially bonking during sleep. And while that’s okay if your goal is to pose in front of a crowd with absurdly low body fat, like a bodybuilder, it’s also a sign of starvation and, if done too long, will cause your body to begin to shut down its metabolic processes.

The bottom line is that everyone’s body responds differently. We all need to exercise and most of us can eat better. In between are a lot of individual variables. When it comes to getting your best possible workout, psychology often trumps physiology. Exercise when you can and pay close attention to your performance. Then choose your preferred workout time based on your results. It’s really that simple.
