David Maus Jr., the internet's premier expert on cold plunging, saunas, and other biohacking tools, makes his return in this episode.

David and I explore the science behind extreme temperature therapy, dive into the mental clarity, recovery, and longevity benefits of cold plunges, saunas, and contrast therapy, and the best ways to fit these practices into your busy life.

We go much deeper than cold plunges and saunas though. We also cover related biohacking topics like red light therapy, acupressure mats, and creatine (the most studied supplement on the planet with lots of benefits that transcend fitness).

If you feel like something's "off," you're ready to take your next step on your fitness journey, or you want to do everything in your power to live as long and strong a life as possible, then listen to this episode.

Here's what David and I discuss in today's show:

• Why contrast therapy is the holy grail for recovery and circulation

• When to choose cold therapy and when to choose hot therapy based on the benefits you're looking to unlock

• How creating an intentional recovery practice is the single most important thing you can do for your overall health and longevity

And more, including these highlights:

• How to boost your mood, energy, and fast track your recovery by doing this simple, yet tough practice (1:15)

• Why you must gradually adapt to colder temperature extremes (5:30)

• Physiological advantages of hot therapy, particularly sauna use, for cardiovascular health and cellular repair (10:20)

• Why contrast therapy is perhaps the single most effective way to recover as quickly as you did in your 20s or 30s (15:45)

• The #1 mistake men make when experimenting with extreme temperature therapy (20:10)

• Are other related biohacking practices like red light therapy, acupressure mats, and creatine supplementation worth it? David explains at… (24:00)

• Why wearing synthetic clothing in a sauna can not only defeat the benefits, but can put your health at risk (38:05)

• How to integrate new wellness therapies into your life (especially if you're busy) (41:30)

About 14 months ago, Dave stepped onto his scale and was shocked:

For the first time in his life, the number on his scale started with a 3. He knew he had to do something different if he wanted to hold and play with his three young grandchildren.

Well, about 14 months later, he's down 100 pounds, or the equivalent of two small grandchildren worth of weight.

But his journey wasn't only filled with impressive milestones. He made his fair share of mistakes (including losing too much weight too quickly, overtraining, and cutting his calories too severely).

Here's what Dave and I discuss in today's show:

• How a combination of weightlifting, walking, nutrition, and Man Flow Yoga led to serious weight loss

• The mistakes Dave made during his weight loss transformation so you don't have to make them yourself

• How community support kept Dave motivated and accountable to his fitness goals

And more, including these highlights:

• The wake-up call Dave experienced after seeing a number that started with a 3 on his scale that resulted in his losing 100 pounds (2:20)

• How losing too much weight too quickly - like losing 60 lbs in 7 months - can delay your fitness goals, drain your energy, and sabotage your metabolism (3:44)

• Why taking weight loss medications without addressing your nutrition, fitness, or habits only results in short-term weight loss, frustrating plateaus, and putting the weight back on (5:42)

• A telltale sign of overtraining that you must listen to or you'll injure yourself (9:07)

• How having a tiny bit of accountability might be all you need stick with an exercise program long enough to slim down, build muscle, and eliminate pain (11:17)

• Why having grandkids is a cheat code for creating a healthier lifestyle (14:18)

• How to avoid developing an "old man's hunch" in your back (17:20)

• This mindset shift helps you prioritize yourself so you can better serve those around you (31:46)

While there's overwhelming evidence between the connection of penis health and cardiovascular health, as we've gotten more data we've learned that penis health is one of the most important health biomarkers. Period.

Nobody has more data than Dr. Elliot Justin, founder of MyFirmTech, which is like an Oura ring (but for down there). His team has analyzed 84,000 erections and have stumbled on some interesting conclusions.

Based on their data, they've realized the importance of nocturnal erections, they've figured out to discover the root cause of ED, and they've uncovered why most doctors' "one size fits all" solutions for problems down there are terribly misinformed.

But perhaps the most impactful thing Dr. Elliot and MyFirmTech is doing is turning a once subjective area of science into objective data. Armed with this objective data, you can regain control over your sexual health or as Dr. Elliot puts it, your "erectile fitness."

And you know what?

The data you get from a FirmTech ring also helps you make smarter decisions in every aspect of your health.

And, of course, it creates more pleasure for yourself and your partner too (which is far more important to your overall quality of life and health than you might think… as you'll see when you listen to this episode).

Here's what Dr. Elliot shares in this episode:

• How your penis health affects your overall health

• The connection between erection strength and cardiovascular health

• How a FirmTech unlocks objective data for your penile health metrics

Other highlights include:

• Why men need to have 3 or 4 nocturnal erections each night (and why having none gives you a 50% chance of heart attack within two years) (2:22)

• The strange way using a FirmTech can show you how diabetes, blood pressure, bad habits, smoking, drinking, and more affect your bedroom performance (and how long you last) (4:02)

• The ONLY way to make data-based decisions to improve your sexual health (4:26)

• The "Nocturnal Erection Test" that can help you figure out the root cause of your ED (6:36)

• Dr. Elliot Justin and his team have analyzed data behind 84,000 erections… here are their biggest takeaways (9:40)

• Why are more cases of ED being reported but we're not seeing a softening of their erections? (10:42)

• How to get harder, last longer, have more confidence, and create more pleasure (for yourself and your partner) with this ring (11:39)

• Why planning for pleasure in your 40s and 50s can improve your sex life, your marriage, and even help prevent divorce (and how to do it) (14:47)

• How an orgasm a day cuts your cortisol levels (the stress hormone) by 25 and 50 percent (19:18)

• How to cut your risk of cardiovascular death (and divorce) in half by having sex twice a week (19:45)

• Why is a FirmTech device better at gauging REM sleep than an Oura ring? (22:46)

• How antidepressants and antihypertensive medications sabotage your penis health metrics (24:51)

Some men are blessed with superior genetics. And other men are at the mercy of their less-than-stellar genetic code.

Today's guest, Man Flow Yoga Member Bob, falls into the latter group with cardiovascular health. His entire family has had some cardiac event that altered the course of their life.

Bob's cardiac event struck when he was 49. While he was out for a run, he started feeling alarming warning signs that made him rush to the ER. Turns out, he had a heart attack.

But you know what?

It's been a quarter of a century since his heart attack - and despite being dealt an unlucky genetic hand, Bob has not let it stop him. In fact, he's used it to up his fitness game… and he's in stellar shape in his mid-70s.

Whether you were also dealt an unlucky genetic hand, you feel the winds of Father Time starting to catch up, or you just need a dose of inspiration from a 74-year-old who's less stiff and achy today than he was five years ago, this episode has you covered.

Here's what Bob shares on this episode:

• Bob's secret to consistency that's helped him stay consistent for decades

• How to outsmart your unique genetic traps with diet and exercise

• Why switching from running to yoga significantly improved Bob's body composition

And more, including these highlights:

• How genetics and stress caused Bob to have a heart attack at only 49 years old - despite consistently jogging for 20 years (and how he upped his fitness game in the 26 years since suffering his heart attack) (2:38)

• A few of the symptoms Bob experienced during his heart attack that may help you recognize the warning signs if it happens to you (3:18)

• How to satisfy your sweet tooth in only 100 calories (11:41)

• Why your body composition can radically change even if you're in your 70s and even if your weight stays relatively stable (17:02)

• The obvious, yet overlooked best way to prevent sarcopenia from setting in as you grow older (20:34)

• How Bob balances yoga, strength training, and regular walks into his weekly fitness regimen (22:34)

• The "extra 10 to 20 percent" secret of having an engaged community attached to your workout routines (27:01)

Despite being the internet's premier expert on cold plunging, saunas, and other biohacking tools… Today's episode with David Maus Jr. took a turn down a far more vulnerable road.

Why?

Because before David was a health and wellness content creator, he had a very different career. He worked in the family car business for 20 years. He was the VP and face of the brand.

But he decided to quit his job a couple of years ago because he felt like something was missing. He was great at selling cars and made great money, but he lacked fulfillment. He didn't want to just tolerate life, he wanted to be passionate about it.

And since more growth is unlocked from vulnerable conversations, that's the route we went down.

Here's what David and I discuss on this episode:

• How David came to the tough decision to quit his job (and how it strained the relationship with his dad)

• Why David's faith kept him grounded and confident during turbulent times

• How to create a life that brings you ultimate joy

And more, including these highlights:

• Why jumping into an ice cold river can completely eliminate your crushing brain fog, fatigue, and even burnout (5:56)

• How to build your own DIY cold plunge in 10 minutes without shelling out $13,000 for one (12:22)

• What led Dave to making a decision to leave his family's car business after 20 years experience to start a YouTube channel (25:00)

• Why faith can make it easier to make a life-changing decision when you don't know whether it's the right move or not (30:41)

• How sharing who you are (instead of what you do) online can almost magically connect you to others who are more like you (42:06)

• Why you can gain a lot from hearing others' religious beliefs (even when you disagree) (51:19)

Most men have to gradually give up their favorite physical activities as they age. Especially when your hobbies are physically demanding - like skiing, hiking, and backpacking.

Today's guest, John, faced this soul-sucking reality a few years ago after getting both of his knees replaced. He had been active his whole life before suffering from orthopedic problems that required surgery.

But you know what?

After his surgeries, which happened when he was 72 years old, John realized that he didn't have to be a victim to his body's stiffness and pain. That's what inspired him to come to the Wellness Weekend in January 2025 (about 18 months after his second knee replacement surgery).

During the Wellness Weekend, he improved his technique in yoga poses. Then, after the Wellness Weekend, he became more consistent with yoga than he had been in the previous 6 years.

The result?

He hiked a mountain that ascended and descended 800 feet. He realized that not only could he ski again, but his balance improved so much that he actually became a better skier. And he recently drove 500 miles (or about 10 hours) in a single trip without getting stiff afterwards.

And he's 74 years old!

John's chockfull of wisdom for being consistent, building your body back up after major surgeries, and keeping your favorite physical activities well into your 70s.

Here's what John and I discuss in today's show:

• Why starting small acclimates your body to working out and makes it easier to stay consistent and grow

• A few simple things John does to stay consistent with his fitness in retirement

• How you can eliminate your aches, pains, and stiffness in your 70s (and beyond)

And more, including these highlights:

• How John bounced back from his health problems that derailed his favorite physical activities for 7 years… and what you can do to enjoy your favorite physical activities in your 70s (2:22)

• Why attending an in-person Man Flow Yoga event helped John conquer his orthopedic problems (3:21)

• What John did after having both knees replaced in 2023 to eliminate his post-surgery stiffness (13:03)

• The simple "Exercise Log" secret that can help you stay consistent for decades (13:49)

• Why a dedicated yoga room in your house removes your excuses for avoiding your next yoga session (15:18)

• Does your body get stiff as a board after 10+ hour driving trips? Here's the most effective way to bulletproof your body from stiffness (20:38)

• The biggest threat to your fitness goals that most men completely ignore (30:13)

If you want to be the youngest and healthiest version of yourself possible, then you need a reliable strategy for working out consistently. Even when you don't want to.

Today's guest, ER doctor and anti-aging expert, Dr. Steven Gabriel almost never wants to work out. But being as young and healthy as possible is important for him. And so, he's developed a few ways to trick himself into working out that he shares with you in this show.

There's a specific reason Dr. Gabriel wants to be as young and healthy as possible:

He's spent years working in the ER and has seen first hand how important your lifestyle is for your longevity. He's seen 80-year-olds who had the energy and vigor of a 50 or 60 year old. But he's also seen the reverse: A 60-year-old who feels and acts like he's 80 or 90.

Here's what else Dr. Gabriel and I discuss in today's episode:

• How men can have more fulfilling and connecting conversations by being courageously vulnerable

• Why it doesn't take as long as you think to learn something new

• And he shares a few of his Jedi mindset tricks for forcing himself to work out when he doesn't want to (which is almost every time)

Other highlights from the show include:

• Parents: Listen to this ER doctor's wisdom about safety (8:07)

• How health consequences compound like bad interest as you age and how to at least not accelerate aging (10:59)

• Why making healthy lifestyle changes, as cliche as it can sound, is the secret to living a vibrant life well into your 80s and 90s (14:34)

• The "Lucky" mindset shift that seems silly, but is surprisingly effective for creating good luck (16:07)

• How moving into a more positive "emotional home" keeps you light and happy even when dark and tragic external events happen (20:43)

• The "2,000 degree stone" secret for forcing yourself to workout that works exceptionally well when you don't want to exercise (25:50)

• The weird way giving yourself 10 minutes to decide if you want to quit gets rid of all the mental gunk that stops you from achieving your goals (48:44)

Tired of doing a form of yoga that causes more injuries than it helps prevent? The cold, hard truth is men need yoga specifically designed for them. Well, here's some good news: You can start your 7-day free trial to Man Flow Yoga by visiting https://shrtlnk.co/kP8M7

From a young age, you've learned how to don various masks for different people. The problem with this is these masks aren't the real you.

But somewhere along the way, whether due to societal pressures, parenting, religious upbringing, or any other variable, you learn that it's safer to be someone else instead of you.

This strategy can work for a while. It's how both Dr. Zac from Movember and I have gotten through life. But it always fails in the long-run because stacking up achievements (personal, professional, or fitness) can't give you the unbridled joy you're desperately seeking.

The good news is that there's a solution. But the bad news is that it's difficult and takes a long time.

The solution?

Learning how to stop overthinking and underfeeling. This is particularly hard for men because we've been conditioned to think instead of feel.

But learning to feel is perhaps the single most important skill you can hone.

In this episode, Dr. Zac and I share the messy story of how we're both trying to feel more and think less - and we invite you to join us.

We also discuss:

• How to take off the masks you're wearing that undermine your growth

• The overthinking and underfeeling crisis that's affecting men

• How the term "toxic masculinity" is unhelpful and harmful to men

Other highlights from the show include:

• How men who do both theater or music and sports in high school don a mask that hinders their personal growth later in life (2:19)

• The insidious way fear discusses itself as freedom of choice (and why this wrecks your relationship, including the one with yourself) (7:20)

• The disorienting "generational trauma" trap that nearly every guy falls into (and how to realize these feelings were never even yours) (15:58)

• Why men are so much better at thinking about their emotions rather than feeling about them - including Dr. Zac and myself (22:15)

• The "feeling is the solution" skill that can help you stop overthinking and underfeeling (22:59)

• How unleashing the grief monster gives you catharsis without drowning in your sadness (40:53)

• Why "toxic masculinity" has morphed into a meaningless catch-all term for bad behavior (and how this undermines men across society) (47:25)
