I do cardiovascular work for two reasons of equal importance...
- For the betterment of my fitness
- For the post-workout increase in mental energy and well being
I usually do some intervallic type stationary bike work. I feel like if I push myself as hard as I naturally tend to, I'll be very tired afterwards... I feel like that's what you need to do to improve your fitness, but I'm missing out on the mental boost.
My question is how to ensure that I'm staying within a proper range to improve my fitness, and still get the mental boost... Or at least within a range, where my body will eventually adapt and I will start getting the boost again.
I only do an hour of cardio, usually every other day, but would like to eventually start every day like that.
