[quote="Riberet19"]
If I do exercise in the morning usually don't get tired, but it also depends on the training and how much energy I spend on it, if I exercise at night I tend to feel much more tired because bedtime is close, but usually I am not one of those who get tired excessively after the training.

I have a couple of friends who prefer to exercise at night because it helps them to get a good sleep after training. So, training at night is a strategy that can help you have a very good sleep. When I was having insomnia,  I began exercising at night in order to sleep well afterwards. So, it is all about when you exercise and why you picked the particular time.
