Progress is a number, not a feeling
We measure every athlete at the start, train what the numbers say, and measure again. Here is what that looks like when we show our working.
The pattern worth noticing
Most training is sold on the vertical jump. It is the easiest number to quote and the least useful one on its own.
Look at the single-leg columns instead. In every athlete below, the weaker leg improved more than the two-footed jump did — and in three of the four, the gap between left and right narrowed.
The framework: the gap matters more than the number.
Amplitude built on a lopsided athlete lands crooked. Closing the side-to-side gap is what makes bigger skills safe to bring down. Closing the
side-to-side difference is what makes the quickness safe to repeat.

Countermovement jump is a two-footed jump from standing. Single-leg jump is the same test on one leg at a time, which is where side-to-side differences show up. These are individual athletes, measured on the same protocol before and after. Results vary with age, stage, starting point and how much training actually happens.
The work behind the single-leg numbers
The column that moved most is the one-legged jump. This is the kind of work that moves it.
What earned progress looks like
What we did not do
We did not cherry-pick the best month or change the test between measurements. Same protocol, same equipment, before and after.
And we are not claiming these outcomes are typical. They are four athletes who trained consistently. What we will claim is that we measured them, and that we would rather show you numbers than adjectives.

My daughter was a young gymnast with big goals. We knew that to give her a chance at reaching them, she needed to add a strength and conditioning program to her training. We saw improvements in her strength, quickness and confidence — all so important in gymnastics — and I believe adding a strength program helped keep her healthy. Aaron created a challenging program but kept things fun.
I came to Aaron to increase strength and fitness to help further an elite gymnastics career. What mattered most was a consistent conditioning routine and nutrition education — strength and power building, plus prehab and maintenance to keep my body feeling its best. He was able to modify and focus on what my individual needs were.
When I entered high school I went back to Aaron for more one-on-one training and an approach more unique to me, given the number of injuries I had sustained. He helped me modify exercises to best fit me as a recovering athlete, so I could keep strengthening the surrounding muscles while the injured ones healed. I was able to perform at my previous level of play from before those injuries.
See where your athlete actually stands
Every athlete here started with an assessment. That is the same place your athlete would start.

Are these results typical?
No — they are individual athletes, and we would be misleading you to present four people as an average. Starting point matters enormously: an athlete who has never trained has more room to move than one who has trained for years. What is consistent is the approach, not the percentage.
Why show single-leg numbers at all?
Because gymnastics loads one leg more than it looks — beam is a one-leg sport, turns pivot on one, and uneven landings catch one leg first. A large side-to-side difference is a known risk factor, and a two-footed test hides it completely. A large side-to-side difference is a known risk factor, and a two-footed test hides it completely. The single-leg test is where it shows.
How often do you re-measure?
Enough to see whether the plan is working and to change it if it is not. Re-testing is part of the programme, not an upsell — a plan that never gets checked is a guess with a schedule.
What if my athlete does not improve like this?
Then we say so, and we look at why. The most common reasons are not mysterious: not enough training actually happening, load elsewhere in the schedule, or a starting point that was already strong. You get the honest read either way.
