Mighty Oak Athletic Podcast S3:E92 - The Dumbest Exercise Your Kid Is Probably Doing - The Dangerous Exercise Taking Over Weight Rooms

Key Takeaways

• Are trap bar jumps safe? Every landing pulls the loaded bar down through the arms and shoulders — that's why coaches cue "land soft and dump the weight." The research behind the trend measured power output, not injuries or shoulder health.

• Does adding weight to a sport movement improve performance? The track record says no: weighted baseballs raised velocity a few percent and injured roughly one in four pitchers versus zero in the control group, and the donut bat makes swings feel faster while measuring slower.

• What builds explosive power instead? Progressive strength in the classic lifts — cleans, jerks, snatches, presses, pull-ups, rows, deadlifts, squats — where the bar finishes racked or overhead and supported. The sport itself supplies jumping at game weight and game speed.

• What should an athlete do about a worrying exercise? Say one sentence: "Coach, can we talk about this exercise?" A coach can only train the athlete they know about, and the response tells families everything.

The Dangerous Exercise Taking Over Weight Rooms

My son came home from college and walked me through his team’s new lifting program. Most of it was solid. Then he got to the trendy one: trap bar jumps.

Picture it. Your kid stands inside a steel frame loaded with weight plates, grabs the handles, and jumps as high as he can. Then he lands. With the weight still in his hands.

Every weight room in America is running some version of this right now. And I think it’s one of the dumbest ideas in sports.

Gravity Always Wins

Here’s the problem — no lab coat required. Gravity doesn’t care that your kid left the ground. On the way down, that loaded bar wants to keep falling, and it’s attached to his arms. Every landing, the weight rips downward through his grip and shoulders while the rest of his body slams into the floor. Coaches even have a survival cue for it: “Land soft and let the weight dump.” When an exercise comes with instructions for surviving the landing, the landing is the problem.

We’ve Seen This Movie Before

Parents of a certain age know how this one ends.

Remember weighted baseballs? Coaches swore that throwing heavier balls would build stronger arms. When researchers finally tested it with high school pitchers, velocity went up a few percent — and one in four kids got hurt. The group throwing regular baseballs? Zero injuries.

Remember the donut bat in the on-deck circle? It makes the game bat feel lighter. Feel being the key word. When somebody actually measured, the donut made the next swings slower, not faster. Hitters have been psyching themselves out for fifty years.

Same trick, new toy. Add weight to a sport movement and you don’t get a stronger version of the skill. You get a slower, distorted version — rehearsed at the exact moment your kid is trying to sharpen the real one. Jumping is a skill. For a volleyball or basketball player, it might be the skill. Hanging a loaded bar off it is the donut bat all over again, with your kid’s shoulders picking up the tab.

And the science behind the trend? The studies measured how much power athletes crank out mid-jump. That’s it. Nobody counted injuries. Nobody checked a single shoulder.

Ten Seconds of Courage

Now here’s the part that actually matters — because my problem that night wasn’t really the exercise.

My son had shoulder surgery a few years ago. Football injury. Months of rehab, the whole ride. And his strength coaches were about to run him through loaded landings without knowing any of it. Not because they’re bad coaches. Because he never told them.

That was the real danger: silence.

So we skipped the rant and practiced a sentence instead: “Coach, I had shoulder surgery a couple of years ago. Can we talk about this exercise?”

Ten seconds of courage. That’s the whole assignment.

And parents, listen: how a coach answers that sentence is the best coaching evaluation you will ever get for free. A good coach leans in, asks questions, and finds another road to the same destination — there is always another road. A coach who rolls his eyes at a surgically repaired shoulder just told you everything.

This is bigger than the weight room. Teach your kid to say the sentence to anybody in charge — coaches, doctors, teachers. Adults can be excellent and still be missing information. Adults can also just be wrong. Your kid is the only person who lives in their body full time, and the only one who can speak up for it in the moment.

What to Do Instead

Get strong at the lifts that were built to build athletes — cleans, jerks, snatches, presses, pull-ups, rows, deadlifts, squats — where the bar finishes racked or overhead, supported, not tearing through your arms in mid-air. Then let your kid’s sport handle the jumping, at game weight and game speed. Strong in the gym. Springy on the court. Never confuse the two rooms.

We’re not training for a season. We’re building bodies — and voices — that hold up for decades.

• Are trap bar jumps safe?

  They're popular and promoted for power, but every landing pulls the loaded bar down through the arms and shoulders — which is why coaches cue athletes to land soft and dump the weight. The research behind the trend measured power output, not injuries or shoulder health. Coach Mike does not program weighted jumps for any athlete.

• Does adding weight to a sport movement improve performance?

  The track record says no. A weighted baseball study raised pitch velocity a few percent but injured roughly one in four pitchers versus zero in the control group, and weighted-bat research shows the donut makes swings feel faster while measuring slower. Adding load distorts the skill instead of sharpening it.

• What builds explosive power instead of weighted jumps?

  Progressive strength in the classic lifts — cleans, jerks, snatches, presses, pull-ups, rows, deadlifts, and squats — where the bar finishes racked or overhead and supported. The sport itself supplies jumping, sprinting, and cutting practice at game weight and game speed.

• What should an athlete do if a team program includes an exercise that worries them?

  Say one sentence to the coach: "I had shoulder surgery a couple of years ago — can we talk about this exercise?" Sharing injury history is not defiance; a coach can only train the athlete they know about, and the coach's response tells families a great deal about the program.
