which cardio to do?

[corvettedudeman]

walk on treadmill incline 15 at 3.6-4mph

intervals on treadmill sprint for 4 minutes walk 1.5

or combo of both 10-15 minutes walking inclne 15 3.5-5mph then intervals until 35 minutes?

I do the treadmill at a 3 degree incline @ 4mph, 30 minutes.

neither.

cardio burns muscle. why would you wanna lose muscle?

If you have fat to burn it doesn't burn muscle, does it?

I found that when I gained 27 lbs while bulking and not doing any cardio, I was like an old man. I got out of breath quickly if I exerted myself at all.

cardio will burn muscle regardless of higher or lower bodyfat.

but then again, if you're over 30% bodyfat and are looking for quick results, then cardio IS for you. you will lose muscle in the process.

I like using the fat burner program on the X-trainer.

ERRRRR....

Satch i do not totally agree with that!!! What happens if you take in enough carbohydrates to burn off during exercise??? The smart bodybuilders use cardio...besides every program should have cardio as the base since that's really our most important muscle. Bro you need to figure out how many cals you are taking in - how many you are expending + how much you will need to grow then from this add carbs for fuel to burn during cardio!!! The lazy man's excuse for not being discliplined enough to stick to the right diet is when they cut cardio out...I.M.O

Cardio oxidizes little in the way of protein. Carbohydrate and fat are the primary fuel substrates used...although there is always at least SOME from each source.

The best way to increase the fat:carbohydrate ratio is to work at a respiratory exchange ratio closer to .7 than 1.0 (range is .707-1.15). At .707 you are burning 100% fat, at 1.0 you are burning 100% carbs, although you can't get to these values in reality.

So the best to burn the most fat is to find out how to work at an RER as close to .7 as you can. You can do this by having an exercise physiologist measure your oxygen consumption and carbon dioxide production during exercise. There are also ways to estimate it, which i may be able to find for you if you want to e-mail me or something.

allright then NINJA...

the first 15-20 minutes, the body will use glucose as the primary source of energy. key word.. PRIMARY.. not necessarily the ONLY source. meaning that it will also use very little fat and muscle. again, only very little.

now after 15-20 minutes what happens?

it starts using fat/protein.

that's no magic.. its science.

not gonna try to go any further as this has been discussed and proven many times before and again.

The evidence backing this is by no means conclusive. There are ways to spare carbohydrate (glycogen) for use later in the activity.

Corvette...look into RER's and how to manipulate them...that's the key to fuel utilization. I'll do some looking for you too...I'm sure I can find something in the next couple of days when i have some free time...school is amother fucker right now
