Who I Work With
Private boxing coaching in Brooklyn is designed for students at all levels.
I work with:
Beginners learning boxing fundamentals
Adults looking to get in shape through boxing
Athletes improving coordination and conditioning
Amateur fighters preparing for competition
Individuals returning to boxing after time away
Many students begin with no prior experience. Private training allows you to learn the fundamentals correctly while building confidence and physical conditioning.
What We Focus On
Each session focuses on developing strong boxing fundamentals while building conditioning and technical awareness.
Training may include:
Proper stance and balance
Footwork and movement
Punching mechanics and combinations
Head movement and defensive awareness
Blocking and parrying techniques
Mitt work and technical drilling
Heavy bag work (when available)
Conditioning and endurance training
My coaching philosophy is defense first. I emphasize footwork, head movement, blocking, and parrying before building offensive combinations. This approach helps students become more technically sound and adaptable over time.

What People Are Saying
“I’ve had the privilege of working with Coach Cosma since August of 2023. Prior to that, I was aimlessly watching boxing tutorials on YouTube hoping to one day be able to compete in the sport of amateur boxing.
Within 4 months, Coach Cosma was able to transform me to be able to compete in my first fight!
What makes his coaching style amazing is that he is patient yet straight to the point when it comes to constructive criticism. This has helped me address various mistakes in my game and solidified my fundamentals to learn new skills day by day.
I could not recommend anyone better if you want to learn to box!”

Classes are well-structured, with each one having a clear purpose. During group classes he always takes the time to give individual corrections to students technique. This personalized attention has helped me identify my bad habits, and prevents me from developing new ones.

One of many things I enjoyed about his coaching style is the more effort you put into his classes the more effort he puts towards you. With that he helped me train and sign up for my first fight which went a lot better than expected and I have his mentorship to thank. Highly recommend him as a coach!”
