Habits and Hustle

You can sleep eight hours, follow all the usual tips, and still feel foggy and sore. If recovery isn’t improving, the problem usually is the environment you’re ignoring at bedtime.

In this episode of Habits & Hustle, I sit down with certified sleep coach Jack Dell’Accio to break down why “cooling” mattresses backfire, what actually drives REM and deep sleep, and how toxins and EMFs keep the nervous system stuck in survival mode.

Jack Dell’Accio is a Certified Sleep Coach with over 20 years of experience studying restorative rest and sleep environments. He is the Founder and CEO of Essentia, a company focused on non toxic, organically made mattresses designed to support neurological and physical restoration.

What’s Discussed


(01:12) Why mattresses are overlooked despite being the biggest sleep exposure


(07:28) REM and deep sleep as drivers of brain detox and physical recovery


(08:44) How EMFs alter blood behavior and keep the brain in defense mode


(15:51) Why mattress toxins stimulate the nervous system and reduce deep sleep


(21:39) How sleep tracking increases pressure and backfires on performance


(24:08) Why most organic mattresses still rely on coils and fall short


(29:22) How “cooling” mattresses fragment sleep through constant repositioning


(42:51) Sleep hygiene versus sleep environment and why people confuse the two

Lifting heavier, training to exhaustion, and pushing through pain are often labeled as discipline, yet they are some of the fastest ways to stall progress and get injured. The real problem is misunderstanding how intensity and reps actually drive results over time.

In this Fitness Friday episode we get into why pushing past your limits is not discipline, what rep ranges actually drive results, and how fitness is increasingly shaping behavior, consistency, and social connection.

Liron Kayvan founded BFLA in 2019. He’s a NASM Certified Group Fitness Instructor, Personal Trainer, and Transformative Life Coach. Liron has competed in Amateur MMA, Brazilian Jiu Jitsu, and Rugby and has been a Fitness Coach for over 10 years.

What’s Discussed


(00:52) Why mastering bodyweight movements should come before lifting


(02:56) How machines allow higher intensity and safety without perfect form


(04:36) Why workout intensity matters more than how heavy you lift


(06:02) The rep ranges that actually support strength and muscle growth


(13:40) How group fitness creates consistency through structure and accountability


(15:00) Why fitness spaces are replacing bars as social connection hubs


(17:56) How padel and running clubs blend movement, community, and lifestyle


(22:07) Why pickleball and other “low-impact” sports carry unexpected injury risk

Aging gets sold as this quiet slide into joint pain, low energy, and moving less because “that’s just how it goes.” The truth is far more uncomfortable: loss of strength and muscle, not age, is what actually limits people long before it needs to.

We dive deeper into this in the latest Habits & Hustle episode with Dr. Vonda Wright. We also get into why running doesn’t ruin your knees, why the body’s critical decade sits between mid-thirties and mid-forties, and why muscle isn’t about looking a certain way, it’s about staying capable.

Dr. Vonda Wright is a board-certified orthopedic sports surgeon with more than two decades of clinical experience. She is a published author and international speaker specializing in musculoskeletal health, longevity, and performance. She also works as a biotech consultant and elite sports physician.

What We Discuss:


(14:58) Why joint pain, muscle loss, and slowing down are not inevitable with age


(16:11) When real physical performance decline actually begins


(21:13) Running, joint health, and what actually causes knee breakdown


(22:45) Why weakness and poor mechanics hurt runners more than mileage


(42:36) Why the body’s "Critical Decade" sits between mid-thirties and mid-forties


(43:40) The "minimum effective dose" for training when you are short on time


(01:12:45) Facing the "fear of being bold" and taking action for your health

Every January starts with big fitness intentions, and it usually ends the same way, routines quietly fall apart once motivation wears off. The real issue is well known: building habits around feelings and calendar dates instead of non-negotiable standards.

In this Fitness Friday episode, we break down the New Year fitness cycle with Liron Kayvan and talk about how to approach it in a way that actually sticks. We get into why walking is the most underrated habit in fitness, how non-negotiables put discipline on autopilot, and what truly separates people who stay consistent from those who fall off every January.

Liron Kayvan founded BFLA in 2019. He’s a NASM Certified Group Fitness Instructor, Personal Trainer, and Transformative Life Coach. Liron has competed in Amateur MMA, Brazilian Jiu Jitsu, and Rugby and has been a Fitness Coach for over 10 years.

What We Discuss:


(00:00) Why New Year goals fall apart by mid-January


(02:48) The New Year reset cycle and why starting dates don’t create consistency


(05:52) How too much daily decision-making sabotages long-term habits


(09:18) What it actually means to build non-negotiables


(14:46) Interval walking explained and why it’s trending for 2026


(20:02) Recovery as a top fitness trend and what’s driving the surge


(24:37) Cold plunges, saunas, and why sleep is the most underappreciated recovery tool


(30:51) Training early and why prioritization matters more than motivation

Weight loss has become a race to get smaller, even when the body is clearly breaking down in the process. The surprise is that a lot of people lose weight and end up more fatigued, under muscled, and metabolically worse off than when they started.

We dive deeper into this topic in the latest Habits & Hustle episode with Ashley Koff. We also chat about why GLP-1s make people skinny but not necessarily healthy, why weight often comes back after stopping GLP-1s, and why not eating enough while on these medications is one of the biggest mistakes people make.

Ashley Koff, RD is a registered dietitian, founder of The Better Nutrition Program, and a clinician with over 25 years of experience in personalized nutrition. She is the USA Today bestselling author of Your Best Shot (HarperOne) and founder of The Better Nutrition Program (BNP), and has been recognized as one of CNN’s Top 100 Health Makers.

What We Discuss:

(00:00) Why weight loss has become the wrong goal and how “thinner” replaced healthier(03:12) GLP-1s explained and why they make people skinny without making them healthy(07:08) The real issue with GLP-1s and why misuse creates rebound weight gain(12:41) What actually happens when appetite returns after stopping GLP-1s(17:56) Why not eating enough on GLP-1s leads to muscle loss and metabolic slowdown(22:38) Food noise, hormones, and why appetite is not a willpower problem(34:27) The biggest “just eat less” lie and how it backfires long term(40:03) Fasting, under-fueling, and why trendy restriction worsens outcomes for some people
