Fat Free Mass Index Explained: A Better Body Comp Metric for Athletes with Dr. Andrew Jagim, Doug Larson, Travis Mash & Dr. Mike Lane #837

In this episode, Doug Larson, Dr. Mike Lane, and Coach Travis Mash sit down with Dr. Andrew Jagim, Director of Sports Medicine Research for the Mayo Clinic Health System, to talk about what actually works for building stronger, more resilient young athletes. Andrew shares how his applied research feeds directly back into real-world coaching, especially for under-resourced D3 athletes, and why the best youth training is simple, fast, and consistent. The group also trades notes on training their own kids: short sessions, minimal setup, and keeping things engaging so the habit sticks for life. They break down practical youth strength programming: unilateral work for stability (step-ups, lunges), basic patterns (kettlebell deadlifts, goblet squats, push-ups), and building hips/glutes to protect knees, especially for tall, fast-growing athletes where coordination and lever changes force constant "auto-regulation." A major theme is injury prevention without turning training into a grind: 15–25 minute workouts, circuits/supersets, park workouts with med balls and kettlebells, and even sneaky "commercial break" core work to keep kids moving while still letting them be kids. The conversation shifts into sports nutrition, body composition, and a more athlete-friendly way to talk about physique, Fat-Free Mass Index (FFMI). Andrew explains how FFMI is calculated, what typical ranges look like for male and female athletes, and why it can be a more positive metric than body fat percentage, especially for female athletes where messaging can backfire. They close with a nuanced look at weight cutting in wrestling and combat sports: why massive cuts are physiologically brutal, how rules differ inside vs. outside the U.S., and why frequent dehydration (like in-season scholastic wrestling) is a completely different risk profile than occasional cuts with longer recovery windows.
