no way .
its amazing how much you can do with just your freakin bodyweight.
EX i pull the sled for over a mile with a 45 on it(90lbs)
very good relaxing conditioning
a little off topic: I want to make 40-50 feet rail setup in my yard
to pull super heavy weight on the sled, to mimic the tread sled
at WSB. except this you use your arms and your ars.

You are already gylcogen depleted (especially muscle I would have thought, liver should still be pretty full) and many people end up training at too high an intensity. I know I did before I bought a HR monitor. Measuring HR when your near max is easy as the blood is (obviously) really coursing through your veins, but when I do low intensity cardio, trying to measure my HR while still on the machine (stair climber normally) can be very hard and wildly inaccurate. Once I bought the HR monitor, I found I had to drastically cut the intensity to keep my HR below 65%. Problem is, cardio then feels too easy so without knowing your "real time" HR, it is very easy (and human nature) to increase the intensity until you start to feel like the cardio is working.

There is nothing wrong with hitting the high HR (in fact it is benificial for cardio vascular conditioning), just make sure that you have the pre WO meal/shake and dont try to keep going for too long.
Twenty minutes of moderate/high intensity is long enough to confer both fat burning and cardio vascular conditoning benefits. If you must do cardio for longer (which I doubt many here would feel the need to ), then split it up into 2 sessions (AM and PM). Same benefits without the risk.

Actually Liver glycogen is used primarily to keep blood glucose levels from falling to low to support the brain and nervous system while you sleep. Muscle glycogen can be full to the brim when you wake up in the morning but liver glycogen will always be depleted.Originally Posted by Andrew69
Remember. Muscle glycogen can only be used by the muscle it is stored in during execise. It is not released into the blood stream to bring up blood glucose levels like liver glycogen.

Also, some of the HIIT advocates will tell you that cardio will turn your fast twitch fibers into slow twitch fibers, but they fail to realize this won't happen since we already train with weights. This was at least the claim of one dude at my gym
