110s can be a great workout. Most coaches who watch this make two mistakes which ruins the workout: 1. You aren't Alabama. They're fitness is more homogenized. They can kind of get away with generic time targets. Any HS team can't. Group people by ability, not positions. Put them in smaller groups, gave them a target that aligns with the adaptation your after. And instead of seeing a failure to hit that target as some lack of effort, see it as information. There endurance wasn't able to hold up to the task demands. Adjust the targets, and build up in the future. OR adjust their rest periods to keep them going (i.e., sit out after 10, etc.) 2. Stop with the if everyone doesn't make it, the whole team runs again nonsense. If that's your mindset you are NOT training for an adaptation. You are NOT 'conditioning' them. You are punishing folks who are correctly riding that line, and potentially overtraining people who did the workout right, just because someone else ran slower. It's dumb. Don't do it. Football conditioning is a copycat game. HS coaches are going to see this and copy it. Stop. Pause. And ask: 1. What's the point, what adaptation am I after? 2. How do I manipulate the variables (speed, recovery, groupings, reps, sets) to get the productive adaptations I want.
