Listeners, you know how much I love to talk about sprinting and recommend adding sprinting (truly explosive, all-out, maximum efforts) to your training regimen for all the wonderful health, fitness, and longevity benefits that accrue—which is why it was such an extreme privilege to welcome Lion Martinez to the show. Lion happens to be the fastest human who has ever lived over the age of 45 and he has broken more than a few world records (such as a 10.72 world record in the masters 100 meters championship in 2023). He is dominating the sport right now, and also coaches a group of master sprinters and young, elite sprinters near his base in Stockholm, Sweden. Every person in his group has set personal best in successive years—not a surprise when you learn about his very scientific, methodical approach to sprint training.  The episode with Lion gets a little technical at times as we discussed some of the science of the energy systems and the parameters of training and recovery, but he did a wonderful job explaining this in a way everyone can understand, and all athletes and fitness enthusiasts will get a lot of value out of hearing some of these important principles—especially how to integrate explosive, high intensity workouts into your training regimen, and most especially, how to do them correctly so you don’t pull a hamstring or get injured!   LINKS: Brad Kearns.com Brad’s Shopping page B.rad Whey Protein Isolate Superfuel - The Best Protein on The Planet!
