Like I said I think there's a balance. I don't always think that the body finds the best technique when it's tired (not that it can't), but I think it can also look for the easiest technique which as I'm sure we can agree easy doesn't always mean better. Also sometimes when I'm tired I overthink things too, sometimes I even develop a progressively worse attitude which results in worse and worse quality in the things I'm practicing. Thanks for your input, I'm sure it's going to sound like I disagree with everything you said, just to be clear I don't. I don't have all the answers and I think there's a lot of grey area, I just like to argue the other side to as a means to explore this idea in greater depth. I think discussions such as this will someday lead to real fact and hopefully a more optimal and efficient way of training/improving, not just in muay thai, but in all things. Thanks again for your input.
