Aerobic means "with oxygen". Your body will break down glycogen to glucose, which reacts with oxygen to produce carbon dioxide, water and releases energy.
Here's how to determine if you are working out within your fat burning/cardio zone:
First you need to figure out your maximum heart rate, or MHR.
(220- your age= max heart rate)
Our fat burning/cardio zone is between 65-85% of your maximum heart rate.
- (220-your age) x 65%= your low cardio zone
- (220-your age) x 85%= your high cardio zone
Here's an example for a 25 year old.
2. (195) x .65= 126.75...so 127
3. (195) x .85= 165.75...166
In this example the client should keep their heart rate within 127-166 in order to be working aerobically.
When I workout I use a Polar Heart Rate Monitor, so I don't have to worry about trying to count my pulse. It shows me my heart rate, along with the calories I've burned. It helps to motivate me and makes me work a little bit harder to ensure that I'm working aerobically.
PLF Daily Tip: Know your own cardio zone and get a heart rate monitor to track your heart rate and the calories you burn!
