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.
A quick player built on a lopsided athlete is a player driving and landing off one leg. 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.

I came to Aaron to increase athleticism and power. He helped develop my functional movements as a professional basketball player — increasing my performance while decreasing my chance of serious injury on the court. He was a big proponent of ankle mobility, which was new for me and something I had not concentrated on before. I only wish I had found him earlier in my career.
My daughter wanted to physically prepare herself to compete at the DI level in basketball. She came away with real knowledge of strength and speed training, which she believed helped with injury prevention. Several people commented that she looked quicker on the court, and I noticed growth in her confidence. She believes her training with Aaron was a turning point in her development as an all-around athlete.
I trained with Aaron the summer before my college basketball season and achieved a personal best across all pre-season fitness tests — the beep test, squat and bench. The increased endurance let me last longer at higher sustained effort in practice and games, and the added strength was evident when going for rebounds. I still do similar training two or three times a week.
See where your athlete actually stands
Every athlete here started with an assessment. That is the same place your athlete would start.
Request an assessmentQuestions parents ask
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 basketball is played on one leg more than it looks — every drive pushes off one, every layup lands on one, every cut plants one. 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.
