Stop counting reps and start watching the bar slow down

Bar velocity tells a thrower whether today's session is doing what it was written to do, and a rep scheme written in January cannot.

Five sets of three at eighty five percent. Written six weeks ago by a coach who had no idea whether the athlete would sleep badly on Thursday, fly on Friday, or arrive with a head cold. The plan is a guess with authority.

A cheap linear encoder on the bar changes the argument, and it changes it in a way I think most strength coaches still underuse. Velocity at a given load is a direct readout of what the athlete can express today. If a lifter's second rep at a hundred and forty kilograms comes out fifteen percent slower than his normal, he is not going to do productive work at that load, whatever the sheet says. If it comes out faster, the load is too light for the quality being trained and he should be adding weight rather than grinding out the prescribed number.

For throwers this matters more than for anyone else, because the whole point of the weight room in a throwing programme is rate of force development, and rate of force development is the thing that disappears first when an athlete is fatigued. Total tonnage looks fine. The quality that transfers is gone.

So set a velocity floor and stop the set when the bar drops below it. Not when the rep count says stop. The athlete who was written down for fifteen reps might do nine on Tuesday and eighteen on Saturday, and both of those are correct sessions.

The objection is that some adaptations need accumulated fatigue, and hypertrophy is the obvious one. That is fair. A shot putter trying to add eight kilograms of usable mass in the autumn should absolutely be grinding, and velocity cutoffs would sabotage it. Use the tool where it belongs, which is the conversion and competition phases, and put it away in the general block.

The second objection is cost, and it has largely evaporated. The devices are no longer laboratory equipment. A club can own one.

What actually stops adoption is that autoregulation makes a coach look less decisive. A plan with fixed numbers is a document you can hand to a governing body. A plan that says stop when the bar slows down is a judgment you have to defend every week.

I would rather defend the judgment. The alternative is a season of technically perfect sessions that miss the athlete standing in front of you.
