The impact of stress has been one of those things that’s surprising in its effect size. It’s something that most people would consider as the main intervention for longevity.”“Reducing stress is incredibly impactful.” “We know physical activity is impactful but it’s not the same effect size as things like BMI or stress.” Listen to the SuperAge podcast wherever you get your pods.

Dr. Max Testa discusses nitric oxide, the benefits of exercise, how everyone’s diet and fitness is personal to them, heart rate, and more. “At the end of the day, you have to go back to basics. Your diet has to be mainly based on healthy food.” “If your blood pressure goes down, your heart has to spend less energy to pump the same amount of blood per minute.” “Often we hear the concept of exercise as a medicine or exercise is medicine and there is nothing more true than that. Exercise has some pharmacological-like effect on the body.” “Not everyone responds to the same training.” “I start with what the science shows, for sure, but then I tell my patient, ‘The result is not as good as I was expecting; maybe we should try this other thing.’ Sometimes you have to try more than once to find the right balance.” “Everything about exercise and nutrition is multifactorial. You have to find the key to open your own door.” Listen to the SuperAge podcast wherever you get your pods. Connect with Dr. Max Testa:WebsiteSay hi to the AGEIST team!

Joel joins us to discuss the importance of aerobic conditioning, how to properly recover, the importance of stress, and more. “To me, performance is living a healthy, long life where you’re free of disease and you can do all the things that you love doing.” “Exercise, strength, and conditioning activity, they are tools to make our bodies more resilient to stress.” “Aging is really just the accumulation of stress over the course of our lives and ultimately our bodies lose the ability to adapt to it and then we start the declining process. If we can make our bodies much more resilient and much more stress capable, then we can delay that process significantly.” “You’ve got to get enough sleep. Sleep is the #1 thing. If you’re not getting sleep, you’re severely limited because that’s when your body is the most recovery driven.” “I have a really simple rule for most people. 80-90% of the time when you walk out of the gym, you should feel at least as good as when you walked in, if not better. You should not walk out of the gym feeling exhausted and defeated and destroyed.” “Exercise is the single most powerful tool that we have.” “If you have really bad genetics and you have a shitty lifestyle, it can catch up to you pretty fast.” Listen to the SuperAge podcast wherever you get your pods.

Our DNA is constantly listening to its external environment and then it’s making changes. Are we in a healthy environment? If so, let’s turn on the healing genes. Let’s turn on the stem cells for us to heal. But if it thinks that we are in a stressful environment, it’s going to turn up those inflammatory genes.”“How we live our life is actually medicine. Our biography actually affects our biology.”“If I want to become a better version of myself, what’s stopping me? What’s the thing that keeps stopping me? It’s probably old ways of thinking, feeling, and acting that finds you stuck.” “If we could start to take challenge as an opportunity, do whatever it takes to upgrade ourselves, to overcome that challenge, we’re suddenly a stronger version of ourself; we’re a more resilient version of ourself.”Listen to the SuperAge podcast wherever you get your pods.Connect with Dr. Kien Vuu:WebsiteInstagramFacebookLinkedInThrive State BookSay hi to the AGEIST team!

My friends that are older, when they were turning 50 they were talking about slowing down and I’m adding to. I’m adding to my physical labor, I’m adding to my mentality. It’s a totally different mentality than, say, my parents.” “Financial issues are a major cause for divorce.” “Money can be an emotional discussion and something that people are afraid to talk about with each other because they don’t want to get in a fight.” “A very valuable piece of living longer is removing stress. Take your stress away. And if your stress is about money, or family dynamics, or who's going to inherit what, and those types of things, let somebody help you. It’s so much easier.” Listen to the SuperAge podcast wherever you get your pods.Connect with Fanci:LinkedInEmail: Fanci.Worthington@ceterais.comDisclaimer: Fanci Worthington is a Financial Advisor offering securities and insurance products offered through Cetera Investment Services LLC, member FINRA, SIPC.
