Throw the baby out with bathwater and LSD?

Here we are, it's Friday again and I'm talking about babies doing LSD in the bath? NO. What I am talking about is how quick we are to throw out perfectly good tried and true programs for new shiny ones. Take Long Slow Distance *LSD from here on* vs High Intensity Interval Training *HIIT from here on* for instance. It seems like youngsters nowadays (yep, I'm 90 years old) have completely trashed endurance training for short fast and intense training. Don't get me wrong, I'm a huge fan of HIIT, I utilize it with all my clients, it holds major value without a doubt but so does LSD. What I've experienced personally, and with clients, is that the true golden fitness ticket is a mixture of both LSD and HIIT. For example, when I drop my once a week LSD run I notice body comp & performance changes that are not in the positive. I've noticed this in my clients as well. Moral of the story, well, there's a couple so I'll list them: 1. HIIT is good. 2. LSD or Endurance training is good. 3. Mixing LSD and HIIT is GREEEEEAT! 4. If your training starts to feel easy it's time for a change *that wasn't really part of this story but it's true so listen to me because I said so* GET OUT THERE AND KEEP MOVING!
