people go to the gym to do aerobics thinking that they're doing aerobics

when in fact they're doing anaerobic what do these words mean and

how does that impact us aerobic means with air and anaerobic means without air

so when you exercise at a low intensity then you can breathe enough air to

provide the oxygen to support your metabolism once you start exercising

more intensely then you can't breathe in enough air to keep up so you're

exercising sort of without air or anaerobic and what that means is aerobic

as long as you can keep up your body uses primarily fat for fuel it burns fat

and it can keep up but once you start breathing harder once you start

exercising harder then you're trying to suck more air in because you can't keep

up and now the body switches from fat-burning to primarily sugar burning

and now as you're breaking down sugar you can get a little bit of fast energy

but at the cost of lactic acid so as long as you're burning fat you can keep

up you can keep doing it for a long long time when you start using lactic acid

now your muscles start burning and you can only keep it up for so long so the

fat burning you can keep up very long the sugar burning you can't keep up very

long so that's the main difference between aerobic and anaerobic so another

way to approach this is in terms of stress and cholesterol so aerobic

exercise burning fat is a low stress exercise and anaerobic burning sugar is

a high stress exercise and in terms of cortisol the purpose of cortisol is to

provide more blood sugar so when you're falling behind on oxygen so you can't

rely on fat now your body has to rely more on sugar so it releases cortisol

the stress hormone so that you can raise your blood sugar and produce more blood

sugar for that emergency fuel to break down sugar and produce lactic acid so

from that perspective aerobic is a low stress and anaerobic is a high stress so

how can you tell if you're doing aerobic or anaerobic exercise the simplest way

is to notice how you're breathing if you're breathing relaxed if you can

breathe primarily through your nose if you can exercise and maintain a

conversation you are doing aerobic exercise you can breathe normally and

that breathing provides enough oxygen to keep up with your metabolism once you

start panting once you start huffing and puffing once you can't speak a complete

sentence when you're just kind of stuttering simple single words then

you're sucking in you're trying to suck more air in and that's because you're

falling behind so that's a sure sign that you're moving into anaerobic you're

moving into higher stress and you're switching more into burning sugar for

fuel another simple way is to get a heart rate monitor and if you keep your

heart rate below 120 beats per minute in most cases you will be burning aerobic

and if you can get up into the 130 140 range

now you're probably anaerobic and if you go to the gym to do aerobics then most

of those people their heart rates can in the 140 to

160 range so they're doing an aerobic exercise and why does this matter

because you want to do aerobic exercise for a long duration because it's low

stress you can sustain it for a long time without stress in your body or your

nervous system or your adrenal glands or without creating sugar cravings aerobic

you could do for thirty to ninety minutes or even longer if you like those

are things like walking or rollerblading or a leisurely bike ride something you

can do for a long time an aerobic exercise is not a bad thing but don't do

it for a long time anaerobic is for fitness it's for

creating some good stress on the body short-term so those you want to do as

intense as possible so look for future videos on high-intensity interval

training and you want to do them less than 10 minutes as little as five

minutes and you do them only in twenty thirty second intervals so realize when

you go into the gym and you're doing aerobics for 30 40 minutes and your

heart rate is in the anaaerobic range you're actually creating a lot of

stress on your body so that may not be the healthiest thing to do if you want

to get fit then it's not a terrible thing to do if you're young and your

body can take some wear and tear it's not gonna kill you but if you're having

some other stress in your life and you're looking to get healthy then you

do not want to do prolonged anaerobic exercise so if you enjoy this sort of
