Brady Holmer has a Master's degree in Human Performance, writes the incredibly popular Physiologically Speaking newsletter, and has recently run a 2:24 marathon.

He also trains unconventionally: gone are the 100-mile weeks and in place of them are moderate mileage weeks (60-80) with 10+ hours of cycling.

In this episode, we rank the core 3 performance metrics of VO2 Max, Lactate Threshold, and Running Economy and discuss how they interact with physiological resiliency, how they can be improved, and which one is the most important.

"My ankle and knee pain was completely gone in a week. Amazing!" - Kim

"I thought I was on the verge of having to give up running due to severe hip pain and luckily discovered Previnex - complete game changer for me!" - Anna

"I am so grateful for Joint Health Plus! As a certified fitness professional and still an extremely active, competitive amateur athlete, I was getting discouraged with an increase in pain simply kneeling down, or bending down to the floor and getting back up while assisting clients, or in my own training! Once deciding to give this product a try, I was floored when I finally noticed I was not bracing in anticipation of pain when I had to kneel down; not whincing in discomfort upon standing! Thank you, Prevenix!" - Jessica

Joint Health Plus is so powerful because the main active ingredient is clinically proven to reduce joint pain, reduce joint stiffness, and improve joint flexibility in just 7-10 days. It's also clinically proven, not just tested, but actually proven in double-blinded, placebo- controlled studies to protect joint cartilage from breaking down during exercise.

Thank you Lever!

Lever is back as a sponsor and I couldn't be more excited. They make a treadmill attachment that reduces your body weight, letting you run more mileage than you typically could with less injury risk.

They're also trusted by physical therapists, where they're commonly used during injury recovery so you can keep running with less load and impact. They're a "secret weapon" during rehab of many pro runners.

Lever attaches to any treadmill and you hook into it like a harness. It effectively makes you lighter, allowing you to do more running with less risk. So maybe you want to build more mileage, or run hard workouts but you're hesitant because of injury concerns. The pro's have been using Lever for years, letting them get the advantage of more training with fewer injuries.

I had the chance to go for a run using Lever and it was deceptively easy to set up and use. All of a sudden, I was running 7min mile pace with the heart rate of 8:30 pace. You can see it in action on our YouTube channel.
