Derrick Jones Jr. Vertical: A Scenario-Based Jump Training Guide Without the Mistakes I Made

Everything I read about vertical training told me the same thing: more plyometrics, more max-effort reps, more volume. If I actually kept following that advice, I'd probably still be stuck at the same jump—and I'd have more injuries on my conscience. This isn't another Derrick Jones Jr. vertical secrets article. His jumping ability is real. But the program that helps one athlete dunk can make another athlete worse.

There's no one-size-fits-all answer. That sounds like a disclaimer, but after years of coaching athletes, I mean it literally. The right plan depends on your starting strength, injury history, bodyweight, sport, and available time. Anyone who promises you the same program that made Derrick Jones Jr. a high-flyer is selling something.

The Mistake That Changed My Jump Training Approach

In my first year of coaching, 2017, I made the classic mistake. I gave every athlete a dunk package full of depth jumps and max-effort jumping. On paper, the program looked aggressive. In practice, one athlete developed knee pain, another lost two weeks to a calf strain, and the rest plateaued.

Five minutes of verification beats five weeks of correction.

I was so focused on adding inches that I ignored the small problems stealing progress. That's the lesson I keep coming back to now.

Scenario One: You Are Starting From a Low Base (Vertical Under 24 Inches)

This is the scenario I see with beginners. They can't touch the rim, but they want to train like a professional dunker. That order is wrong.

Before you add depth jumps or advanced plyometrics, you need strength and tendon capacity. The fastest way to improve a 20-inch vertical is often to squat, hinge, and do simple single-leg work—not to jump repeatedly.

• Goblet squats or trap-bar deadlifts: 3 sets of 5 to 8 reps, controlled.
• Single-leg glute bridges: 3 sets of 8 reps each side.
• Low-impact pogo hops: 2 sets of 15 to 20 seconds.
• Slow calf lowers on a stair edge: 2 sets of 8 reps each side.

When your vertical is below 24 inches, most of your gains come from building strength and coordination. Depth jumps in this scenario are usually a mistake. I made that mistake, and I'm not going to pretend it didn't cost me time.

Scenario Two: You Can Touch the Rim and Want To Dunk

This scenario is different. You already have some athleticism. Your issue is usually converting strength into speed and refining your approach.

This is where I started using a small amount of max-effort work, but I stopped doing it every session. Here's the plan I now use with intermediate athletes:

• Depth jumps from a 12-to-18-inch box, 3 sets of 3 reps, only on a fresh day.
• Contrast sets: trap-bar deadlift or heavy sled drag, followed by a broad jump.
• One-step and two-step takeoff practice with a real basketball rim.
• A short video review after every session.

If you're in this scenario, the problem is rarely effort. It's technique and recovery. The conventional wisdom says grind through a 12-week program with no changes. My experience suggests the opposite: adjust the plan every time your sleep drops, your legs feel heavy, or a sharp pain appears on landing.

Scenario Three: You Are Returning From Injury or Managing Pain

This one matters more than any program. If you have Achilles pain, patellar tendinopathy, or low-back issues, you aren't in a race to add two inches. You're in a race to avoid a setback that erases four months of progress.

Prevention over cure isn't a slogan here. It's the whole plan.

• Don't start plyometrics until you can do slow single-leg calf lowers without pain.
• Build isometric tendon capacity before you add jumping.
• Keep your hard jump days separate from squat days.
• If one leg is noticeably weaker, fix that imbalance before you train the jump.

The best vertical program is the one you can finish without an injury. The fastest athlete I ever worked with didn't make the roster because he tried to train through patellar tendon pain.

How To Know Which Scenario You Are In

I didn't always separate athletes by scenario. When I first started, I went back and forth between more strength and more plyometrics for two years. On paper, max-effort jumping made sense. My gut said strength was missing. The answer wasn't either-or. It was stage-based.

1. Can you squat below parallel without pain? If not, start with scenario one.
2. Can you touch the rim with a two-step approach? If not, your priority is base strength and technique, not a complex program.
3. Do you have pain when landing from a 12-inch box? If yes, follow scenario three even if you have a 30-inch vertical.

If you answered yes to number two and no to number three, scenario two is probably your starting point.

The Checklist I Use Before Every Jump Block

I created this checklist after my third avoidable mistake. It's simple, but it catches problems before they cost months.

• Measure your standing reach at the same time of day.
• Take a video of your approach jump.
• Check your sleep and soreness for the last seven days.
• Warm up for at least 10 minutes.
• Don't do depth jumps on sore legs.
• If pain appears on landing, stop and remove max-effort jumps for that session.
• Test your vertical once every four to six weeks, not every day.

I've caught more than 30 potential problems with this checklist in the last 18 months. Not clever. Just consistent.

The Bottom Line

Derrick Jones Jr. has a vertical that most people will never match. That's not a reason to skip training. It's a reason to train smarter.

Don't copy his workout. Don't follow a program that promises guaranteed inches in 30 days. Start where you are, decide which scenario fits, and use a checklist to avoid repeating my mistakes. Jumping higher is a long game. Prevention isn't boring. It's what lets you keep jumping.
