Stage 01 · Ages 12–15
Foundational years
The athletic operating system gets built here or it does not get built. Movement patterns, training literacy, mental habits, recovery hygiene.
Most athletes never reach the ceiling they were built for
Not because of talent. Because nobody around them runs the full system on the same calendar. Skills, strength, mind, nutrition, recovery, analytics, mentorship. 369 development does. One coach is not enough. The whole system or none of it.
Robert Mazin · The system that turns a plateau into the next contract
300+ athletes developed across 9 federations. Multi-sport mentorship since 2017.
Most young athletes are not prepared like professionals
Pros have a full system around them: skills coach, strength coach, sports psychologist, nutritionist, video analyst, recovery protocol, mindset work. Junior athletes get a season schedule, a club coach, and a hope.
That gap is invisible until the ceiling shows up. By then it is too late to back-fill the years of professional preparation pro athletes already had. Talent is not the bottleneck. The system around the talent is.
369 prepares our athletes like the pros they are trying to become. Dedicated coaches across every discipline. A real support system. Bespoke routines built to the sport, the age, and the stage. The extra mile, every week, on the calendar. Because no one else is going to do it for them.
The four reasons athletes plateau
3-4
different coaches piecing together training plans that contradict each other. No coordination, no shared notes, no compounding.
0
structured mental work. Every performance ceiling at the top of every sport is psychological, not physical. Most athletes never touch it.
~70%
of junior athletes operate on guesswork nutrition and recovery, plans copied from adult pros or skipped entirely. The body cannot adapt to a load it cannot recover from.
$0
spent on video and analytics. The athletes who go pro see themselves on tape every week. The ones who plateau guess.
369 development was built so families never have to wonder which gap closed the ceiling.
Who 369 develops
369 works with athletes at multiple stages. By age, by current level, by what is in front of them next. Different stage, same standard.
Stage 02 · Ages 15–17
Performance optimisation
The recruiting window. The combine reels. The S&C peaks. Every variable matters because every scout is watching.
Stage 03 · Ages 17–21+
Pro readiness and transition
NCAA. Junior leagues. Pro contracts. The work shifts from building to maintaining under far more pressure than the athlete has ever felt.
What every 369 development includes
Four rooms, one calendar, one principal. The work below is included at every level of the 369 management engagement. The depth scales with the engagement scope.
01
Mentorship & mindset
Direct mentor sessions with Robert Mazin. Sports psychology and mindset coaching. Identity, motivation, and pre-camp work. The mental layer underneath every contract decision.
02
Skills, S&C & video
Skills coach and strength coach coordination across the season. Professional video coaching and technique breakdown. Coach calls and notes that build the same plan, not three competing ones.
03
Analytics & review
Full season analytics. Mid-season progress reports and path correction. Game tape and pattern review on a cadence. Plateaus do not survive a measurement system.
04
Nutrition, recovery & lifestyle
Sport- and age-appropriate nutrition. Recovery and return-to-play protocols. Sleep, travel, and academic monitoring. The unglamorous variables that decide whether an athlete adapts or breaks.
Development runs as one engagement with representation. Depth of coordination scales with the engagement scope, discussed on the call with Robert. 369 does not bill development as an add-on.
What is also included when working with 369
Representation and visibility are not add-ons. They are written into the same engagement, run by the same office, on the same calendar as development itself.

The questions families ask before committing to a development engagement
What does 369 development actually include?+
Mentorship sessions with Robert Mazin. Skills and strength coach coordination. Professional video coaching and technique breakdown. Sports psychology and mindset work. Nutrition, recovery, and return-to-play protocols. Full season analytics and review. Mid-season progress reports and path correction. Lifestyle and academic monitoring. The whole system runs on one calendar from one office.
Why do I need this if I already have a coach?+
Most athletes plateau because the work is fragmented across three or four people who never speak to each other. Skills coach in one gym, strength coach in another, mental sessions a tab open on a phone, nutrition figured out on Reddit. 369 development sits over the top of all of that. Your existing coaches stay; we coordinate them so the work compounds instead of cancelling itself out.
Does 369 run the physical training in-house?+
We coordinate with the skills, strength, and conditioning coaches your athlete already works with, and bring in our network where you do not have one. The 369 mentor is the constant. The specialists are best-in-class for the sport, position, and stage. We do not pretend to be every coach. We run the room they all report into.
How much time does mentorship with Robert involve?+
Direct mentor sessions are scheduled around key moments in the athlete’s calendar: pre-camp, mid-season, off-season planning, contract windows. Cadence is monthly at minimum for active management families, with on-call access when something real is on the table. Robert is not a generic life coach. The sessions are about the specific decisions in front of the athlete that week.
What ages does development cover?+
From ages 12 through professional contracts. The work shifts by stage: foundational pattern-building from 12 to 15, performance optimisation and recruiting prep from 15 to 17, pro readiness and transition from 17 onward. The system is the same; the load and the focus change.
Is mental work optional?+
No. Every active 369 athlete has a mindset and sports psychology component built into their development engagement. Performance ceilings at the top of every sport are mental, not physical. The athletes who go pro have done this work. We make sure ours have done it earlier.
How does development connect with representation?+
They are the same engagement. Representation gets the athlete into the right room. Development is what keeps them in it. Both run from the same office, the same principal, the same calendar. Families do not pay for them separately.
How do I start?+
Submit the application form. Robert reads every application personally. If 369 is the right fit, you will hear back within five business days. If we are not the right fit, we will say so directly and recommend who is.
