Why Drill-Based Coaching Can Hinder Growth

Today’s guest is Sam Elsner. Sam is a former NCAA Division III national champion thrower turned motor learning writer and educator. He’s the author of The Play Advantage and creator of the Substack CALIBRATE, where he explores how humans learn movement through play, perception, and environment design. Sam brings a rare blend of elite athletic experience and deep skill-acquisition insight to help coaches and athletes move beyond drills toward true adaptability and creativity in sport. As athletic performance is largely driven by weight-lifting. It digs into maximal strength and force-related outcomes in such excess that all other elements of athleticism are negated. Skill learning and high velocity movement are the wellspring of sporting success. As such, having a balanced understanding of the training equation is critical for the long-term interest of the athlete. On today’s podcast, Sam and I dive into how athletes truly learn to move. Sam traces his journey from WIAC throws circles to Cal Dietz’s weight room, why a rigid “triphasic for everyone” phase backfired with a soccer team, and how ecological dynamics and a constraints-led lens reshaped his coaching. Together we unpack the strength–skill interplay, 1×20 “slow-cook” gains versus block periodization, the value of autonomous, creative training application. We touch on youth development, culture, and team ecology, plus where pros are experimenting with these ideas. This episode is loaded with both philosophy of training and skill learning, along with practical takeaways in program design. Today’s episode is brought to you by Hammer Strength.

Keep speed, power, and reactive work present year-round in some capacity. Avoid assuming what works for one context transfers straight across to another. 17:49 - Vertical integration instead of siloed periodization Train multiple physical qualities year-round with shifting emphasis rather than isolating one block at a time. This prevents athletes from losing speed while developing strength, or vice versa. Small doses across the year keep qualities alive and connected. 24:58 - Skill learning must reflect the chaos of sport Sport is unpredictable, not robotic. Training should reflect that uncertainty. Use varied environments, movement options, and constraints instead of perfect reps. Skill emerges from exploration, not memorization. 35:43 - 1x20 for strength that supports skill 1x20 builds strength while leaving room for sprinting, jumping, and skill work. The last few reps in a 1x20 set still hit high effort without excessive nervous system cost. Use stance and tempo variations to match individual structure. 43:15 - Autonomy inside the weight room Allow athletes to choose stance width, bar position,
