In “Supertraining,” Mel Siff makes a case for “imperfect training”: occasionally varying the balance of loads, stances, speed and others to better prepare an athlete for sport. Older coaches will remember Paul Chek’s “balance” training for the “core” in the early 2000s. For years, parents visiting my gym would cite the value of “training the little muscles in the core” while talking about their kids. Heck, “core” is STILL a buzzword in training circles of lower educational average. Obviously, the nature of sport is unpredictable. But can the training room best prepare an athlete for that unpredictability? Is the scope of unpredictability different for each sport, and therefore trainable only on the field or rink? “Imperfect training,” in my mind, can be spread across a broad spectrum: – inherently unsafe, with little value (risk > reward) – inherently unsafe, with moderate-to-high value (risk = reward) – inherently safe, with moderate-to-high value (reward > risk) – inherently safe, with little value (risk + reward = 0.) It’s irrelevant to our purposes to discuss activities which create no reward. But all training carries an element of risk. Small “injuries” – including muscle tearing, elevated blood pressure, glycogen depletion and exhaustion – are necessary to spur super compensation. In that light, where is the line between “small injuries created on purpose” and “small injuries that are a side effect”? What about small injuries that cause no real limitation or long-term damage, like blisters? “Imperfect” training raises the risk associated in training. BOSU balls were popular toys (but not with Siff, nor with me) for years. The unstable surface of a BOSU ball was argued to create more stability around the ankle and knee joints. Higher risk for a reward or arguable value. Where do box jumps fit into the risk/reward picture? Low-rep box jumps done from on high? High-rep box jumps done from a medium height? Where is the “safe” line in either scenario? ...

This is an excerpt from Two-Brain Business 2.0.  Early in 2015, I was at a seminar for coaches. One attendee bragged up his box, his coaching and his programming: “I have everything,” he said. “All the toys. We can do anything that pops up at Regionals or the Games. I reinvest every dollar of profit into equipment. We’re the only box in the state with The Pig, I think.”   His programming went like this:   “I wrote down a list of every exercise in the L1 handbook, and I make sure we do every one at least once per month. That way I’m following the true ‘constantly-varied’ model.”   Many coaches believe the same.   But that’s not true. A real training model focuses on benefits, not features. Here’s the difference:   Benefits-based programming for a cop, ski racer and world-class BJJ competitor: “Our goal today is to spend 4-7 minutes in an anaerobic state. This will benefit you, Greg, because after you chase down the bad guy you’ll need enough energy to fight him. It will help you, Eva, by preparing you for all-out effort on a Super-G. And it will help you, Mike, by keeping you in a high-lactate state for the same duration as your typical match. We’ll put you into this anaerobic state with burpee box jumps: you’ll hold your breath for a half-second on each jump, spiking your heart rate and requiring a complex motor tasks while in severe oxygen debt.”   Features-based programming for the same trio: “We’re going to use the new monkey bars today, and then pull the sleds. We haven’t done that in awhile! And then it’s time for a Fran retest! This is gonna be spicy…let’s go!”   The latter sounds like a LOT of fun. And it’s an exaggeration: I could make the case for including monkey bars, sleds and Fran for cops, ski racers and BJJ athletes. But ...
