How much vertical jump can you gain in a year

There's no centimetre figure that works for everyone. How much you gain in a year depends on where you start, how many years you've been training seriously, how consistent you are and how well you recover. Anyone who promises you an exact number before watching you jump is guessing. That said, you can think seriously about what sets your margin. Let's look at it.

Why nobody can give you an honest number up front

The vertical jump doesn't improve in a straight line, and it doesn't improve the same way for everyone. Two athletes following the exact same programme for twelve months can end up with very different results, because they start from different places: one has never trained strength in his life, the other already has five years in the weight room behind him.

The first one has a lot of easy margin to collect. The second has to work much harder to gain much less. It's the same reason someone who starts running takes minutes off their 5K in a few weeks, while an experienced marathoner fights for a handful of seconds.

That's why you won't find promises like "+X cm in Y weeks" on JHP. Not because the method doesn't work, but because that sentence is a prediction nobody can make honestly about a person who hasn't measured yet.

The variables that actually decide your margin

• Where you start. If you don't jump much and have never trained strength, you have the biggest margin ahead of you. If you already jump well, the gains are smaller and slower, but not zero.
• Your training age. Not how old you are: how many years of structured training you have behind you. It's the variable that weighs the most.
• Consistency. Twelve months of real training is not twelve months on the calendar. If you train for three weeks and skip two, the real year gets a lot shorter.
• Recovery. Sleep, nutrition and match load decide how much of what you do in the gym turns into adaptation. A full season with three technical sessions a week leaves less room than a free summer.
• The quality of the movement. Part of the centimetres you're missing isn't strength: it's take-off technique, arm swing, approach rhythm. That part unlocks faster.

A year isn't all the same: how the gains are spread out

In practice the first stretch is almost always the most generous, and not only thanks to the training. Early on you improve because you learn to jump better: you coordinate your arms, you find the right timing, you stop wasting energy. That's technical and neural adaptation, and it comes fast.

Then the curve flattens. This is where you need strength built over time and quality work on how fast you can express it, and that doesn't show up in a few weeks. Plenty of athletes quit right here, convinced they've hit their ceiling, when all they've done is enter the slow phase.

Then there's the season. If you play in a league, your jump tends to behave differently between pre-season, mid-season and the run-in: match load and accumulated fatigue weigh on the number you measure, no matter how well you're working.

The difference between a good year and a wasted one

Wasted years all look alike. Programmes swapped every six weeks because "I'm not seeing results". Plyometrics every single day until your knees give out. Zero base strength because "I just want to jump, not do gym work". No measuring, so no way of knowing whether anything was working.

Good years have three things: a plan that stays in place long enough to produce adaptations, a load that climbs gradually instead of starting at the top, and a measurement at the start and at regular intervals. It's not complicated. It's just boring, which is why few people do it.

How to tell whether you're actually improving

Without a starting number, come December you won't be able to say whether you improved or whether it only feels that way. And "I feel like I'm getting higher" is unreliable data: it depends on the day, on the warm-up, on how you slept.

The cycle is always the same: measure first, then train, then measure again. With the JHP jump test you upload a 2-second video and get your height in centimetres, calculated from flight time. It's free, the analysis runs in your browser and the video never leaves your device.

Two things to watch when you measure again: always use the same type of jump (standing or with an approach, don't mix them) and measure in similar conditions, ideally at the start of a session and after the same warm-up. Otherwise you're comparing numbers that can't be compared.

The JHP programmes, so you don't waste the next twelve months

• Jump Higher Program — 10 weeks bodyweight, €60. The starting point if you don't have a structure.
• JHP Gym Edition — 16 weeks in the weight room, €60. To build the base strength that holds up everything else.
• JHP Vertical Upgrade — €67. For anyone who has already stalled and needs to get the curve moving again.
• JHP Subscription — €99/year: 13 programmes, WhatsApp support, cancel anytime. Full list on the JHP courses page.

In short

I'm not going to tell you how many centimetres you'll add in a year, because nobody knows before seeing you measure. What can be said is what it depends on: your starting point, the years of training behind you, consistency and recovery. And that the only way to know how the year went is to have a number at the start and one at the end.
