SATURDAY PSA: No, leg day is NOT the same as doing cardio.
Want to increase your life expectancy?
Skip trendy “fixes” like:
- NO sugar
- NO gluten
- NO GMOs
- NO diet soda
Instead, pay more attention to (increasing) your cardiorespiratory fitness (CRF) or lack thereof.
I am horrified at the lack of cardio being performed among otherwise “fit” people or those claiming to want to improve their health & body composition.
Cardio is not a dirty word & will NOT magically ‘steal your gains.’
Benefits of cardio: Cardio helps increase the strength of your heart and lungs. With regular aerobic exercise, your heart will eventually be able to pump more blood and thus deliver more oxygen with greater efficiency.
Moreover, your muscles will develop a greater capacity to use this oxygen. Because your heart is stronger, it can pump more blood per beat, and as a result your heart rate, both at rest and during exertions will decrease. Your heart will also acquire the ability to recover from the stress of exercise more quickly.
“You can be normal weight or “in-shape”, be strong as an oak, eat healthy, or even have a six pack, but you still have a higher risk of mortality or heart disease compared to a person who is normal weight and has a higher CRF than you.” (from link below)
So be proactive with your health, get moving, stop making excuses and repeating stupid stuff you hear the ‘cool’ kids saying.
FYI: It’s not “cardio” if you’re not working at 50% of your HRM for at least 15 mins. More is even better. See chart in comments for age & HRM.
