I am often tired after my big strength training workouts, and it's ok. Make sure you are eating properly (including pre and post workout meals) and getting enough sleep.

Nutrition is one of the biggest factors that effects how you feel during and after a workout. Pre-work out meals and post-workout meals are extremely important and vary depending on the type of workout you are doing. If you are working with a trainer of any worth, they should be able to advise you as to what would be considered an appropriate pre/post workout meal.

There are some thoughts that come to mind, and one is with your nutrition. I had a peek at your Nutrition Tracker, but you don't seem to use it often - do you record elsewhere? Ensure that you are eating enough to sustain your exercise at the gym. Remember, too few calories can cause this. Below is a link that may give you ideas for that:

Are you getting a good mix of nutrition, as in plenty of lean protein, lots of fruit/veges, and in a variety of colour, and complex carbs (in the form of wholegrains, etc.)

How much sleep do you get over-all? .... AND is it quality sleep?

Do you have any health conditions - i.e. Diabetes etc., that could contribute to this problem?

Are you on any medications?

Apart from the work-outs, are you doing anything different on those days, than you do on the other days?

I experience similar when lifting weights. I'll feel nice and warm after a workout, but later that night and often the next day will be worn down.

I've recently found a good nights sleep helps with workout soreness. I began sleeping on a grounded bed sheet a month ago. As a result I discovered I'm sleeping better, and not nearly as muscle fatigued after lifting. The tiredness situation though hasn't improved.

Are you eating enough through the day ? Do you eat a post workout or even a pre workout snack ? What are you eating ? Are you getting the mid afternoon slump ?

When someone tells me they feel tired after working out in the morning, one thing I ask them is what they have been eating. food = energy and no food = no energy. So, do make sure you're eating enough to support your vigorous workouts. It could be that your body isn't getting enough fuel for the day and as such, you get sleepy.

Also, what are you eating ? If you get a mid afternoon crash, you may be eating a little too much sugar. Do you eat yogurt ? Don't get me wrong, I love yogurt. However, one 6oz cup of yogurt could have as much as 20grams of sugar. that's 5 teaspoons worth of sugar. so, do watch the amount of sugar you eat during the day. eating a little too much sugar could give us an energy rush in the morning followed by a crash in the afternoon.

are you drinking enough water ? you could be dehydrated. that's a possibility. are you under any unusual stress ? Stress can cause us to feel sleepy too.

Are you continuing to hydrate yourself after leaving the gym?

Are you getting 7-8 hours of sleep each night?

I would assume that your body isn't yet used to all the extra exercise yet. It might take a while for your body to adjust, especially if you are really pushing yourself. I know when I first started working out regularly I was tired on the days I would work out too. Now I feel crummier on the days when I don't exercise!

When I go to the gym and work out, I come home energized....for a few hours. After that, I am actually more tired than before I went or, than on days when I DON'T go to the gym.

Why is that!?

I mean, I can seriously take a nap right now, 5 hours after getting back from the gym...

I am sleeping much better since working out and I don't feel the need to nap on days I don't workout.

I've been working out for about 6 weeks now and 4 of those weeks has been with a personal trainer who pushes me more than I push myself.
