The 21-Minute Workout That Rewires Your Muscles, Your Brain, and Your Excuses

Most people don’t fail at fitness because of time — they fail because of how they use it.

In this episode of Hacks and Hobbies, Junaid sits down with PJ Glassey, founder of X Gym and creator of a radically different training methodology that compresses three and a half hours of traditional strength training into just 21 minutes, twice a week. If you’ve ever told yourself “I’m too busy to work out,” this conversation will completely dismantle that belief.

PJ explains why the traditional fitness model was built for 1891 bodybuilders, not for modern high achievers with families, careers, and creative projects. He breaks down time under tension, complete muscle fatigue, and why the way most people lift weights actually builds in tiny “rests” that sabotage results. We also go deep into adaptation, plateaus, fear of failure, and why having a “posse” of support might be the single biggest lever for your long-term health.

By the end, you’ll know exactly how to start — even if you’re deconditioned, overweight, or haven’t seen the inside of a gym in 20 years.
