The 4-in-1 method: a complete high-performance tennis system
Four pillars to build the athlete, four areas of expertise to build the career. One coach, one player, one family, one staff — and everyone sees the same picture.
Four pillars to build the athlete.
Measured, not guessed. Each pillar has its own tests, tools and indicators — and they all feed one individual plan.
Tennis movement & biomechanics
Real data, real results. Understanding how an athlete moves, balances and generates force — with Kinvent force plates, injury-prevention screening and our own Single-Leg Reactive Split-Step (SL-RSS) test.
Explore biomechanics →High-performance training
Strategic decisions, optimised time. Every session tracked with Baseline Vision — more than 30 performance indicators — combined with video analysis to guide technical and tactical choices.
Explore training →Physical & mental training
Physical resilience, mental strength. The 30-15 IFT test for repeated high-intensity efforts, training load monitored with 4 key indicators, and decision-making under pressure on and off court.
Explore conditioning →Invisible training
24/7 performance. Recovery, sleep and wellbeing — compression boots, cryotherapy sleeves, sleep and heart-rate variability tracking — plus Blazepod reaction work and the habits of a professional.
Explore invisible training →Four areas of expertise to build the career.
Everyone sees the same picture.
Goals, training programme, load, wellbeing, tournaments and match reports — centralised in the J2Pro Circuit app for the player, the family, the staff and the agent.
The 4-in-1 method — questions
What is the JuniorToPro 4-in-1 method?
A high-performance tennis system with two layers: four pillars to build the athlete (biomechanics, high-performance training, physical and mental training, invisible training) and four areas of expertise to build the career (coaching, performance management, data and match strategy, travelling coach).
Which tools do you use?
Kinvent force plates and sensors, Baseline Vision shot tracking, video analysis, the 30-15 IFT test, Blazepod reaction training, recovery tools such as compression boots and cryotherapy sleeves, and the J2Pro Circuit app for load and wellbeing monitoring.
Is the method only for professional players?
No. It is designed for the whole pathway, from Tennis Europe juniors to the ITF World Tennis Tour and the WTA. The tests and training loads are adapted to the age and level of each player.
