How to Dunk a Basketball Like Ja Morant
Ja Morant is only about six foot three, yet he throws down some of the most explosive dunks in the NBA. The secret is not just raw height, it is a trainable mix of speed into the jump, single leg power, and perfect timing. This guide breaks down how to build that kind of bounce and get your own first dunk, step by step.
What Makes Ja Morant's Dunks So Explosive?
Watch Ja closely and you will notice he almost never gathers from a dead stop. He builds speed on the approach and converts that horizontal momentum into vertical lift off one foot. That one foot takeoff is the same move a long jumper or high jumper uses, and it lets a shorter player rise fast before the defense can react. His power comes from strong hips, springy ankles, and a violent arm swing that pulls his body upward.
Here is the good news for you. Every one of those pieces can be trained. You do not need to be born with hops. You need to get stronger through the hips and calves, teach your body to plant and explode in a fraction of a second, and practice the timing of your last two steps until it feels automatic. Master those and the rim starts to feel a lot closer, whether you are chasing your first clean dunk or trying to throw it down with authority.
Pay special attention to the second to last step, often called the penultimate step. Great jumpers lower their hips slightly on that step to load like a spring, then attack the final plant. If you sprint in tall and try to jump off stiff legs, you leak all your momentum into the floor. Learn to gather low and long on the approach and you will feel the difference on your very first session.
How High Do You Need to Jump to Dunk?
Your standing reach matters just as much as your height. A player who can touch high on the backboard needs far less vertical to finish at the rim, which is set at ten feet. Use the chart below to find your rough target. Remember you need to clear the rim by a few inches to control the ball, so add about six inches of margin.
| Your Height | Typical Standing Reach | Vertical Needed to Dunk |
|---|---|---|
| 5 ft 8 in | 7 ft 6 in | About 30 in |
| 5 ft 10 in | 7 ft 8 in | About 28 in |
| 6 ft 0 in | 7 ft 10 in | About 26 in |
| 6 ft 2 in | 8 ft 0 in | About 24 in |
| 6 ft 4 in | 8 ft 3 in | About 21 in |
If those numbers feel far away, do not worry. A focused athlete can add eight to twelve inches to a vertical over a training block with the right jumping and strength work.
What Gear Builds Real Hops?
Bodyweight jumping gets you started, but adding resistance to the exact movement of a vertical jump is how you build serious explosive power. Training bands that run from your waist to your heels load the jump on the way up and force your hips, quads, and calves to fire harder on every rep, so game day feels light and springy.
The beauty of banded jump training is that it targets the exact pattern you use to dunk instead of a random gym machine. You are teaching your body to produce force fast in a real jumping position, which is what carries over to the court. Pair a few sets of banded jumps with your bodyweight work and you build both the strength and the speed side of your vertical at the same time.

Waist to heel bands add resistance to every jump so your hips and calves build the explosive power a Ja Morant style takeoff demands.
What Drills Help You Dunk?
Run this simple progression three days a week with a day of rest between sessions. Quality beats quantity, so rest fully between reps and jump with maximum effort every time.
Dunking questions players ask
How long does it take to dunk?
With consistent jump training and strength work, many athletes add the inches they need in one to three months. Your starting reach and age play a big role.
Should I jump off one foot or two?
Off a run, one foot like Ja is usually higher and faster. From a standstill under the rim, two feet is more stable. Train both.
Do resistance bands really help my vertical?
Yes. Loading the jump pattern with bands builds the explosive hip and calf power that bodyweight jumps alone cannot, as long as you train with full effort.
Is dunking bad for my knees?
Not when you build strength first and land softly. Depth drops and controlled landings protect your joints while your power grows.
