Professional basketball is a rigorous, physical and extremely competitive business.
Professional basketball players are progressively becoming more and more athletic, stronger and talented.
Each year, the NBA and international leagues become more and more challenging and exciting.
Therefore, it is of the utmost importance that players continuously prepare themselves both physically and mentally. A player’s offseason is critical to his success in the league they compete in. SIG works to make sure that our clients have access to the top basketball and physical trainers, in the best possible facilities.

SIG puts together position-specific camps and training sessions, run by some of the best coaches and trainers in the business. During these training sessions, whether they are individual or with a small group, SIG clients will benefit from hands-on coaching and evaluation, and will be pushed hard to improve their games. They will find themselves turning their weaknesses into strengths, and they will be ready to come to training camp with improved knowledge, skill and work ethic. SIG clients pride themselves on always being ready – be it for a workout, combine, NBA Summer League or the NBA regular season and playoffs.
Training is a vital part of a professional athlete, and SIG’s clients train with the very best.

“Being a part of the SIG sports agency is like being a part of another family. They make you feel like a family member versus a client with the true personal attention and the amount of time and effort they put into helping develop your career.”

“SIG is not just an agency, it’s a family. From day one everyone in the agency has accepted me, not only as a client, but into the bond that they all share. I know I’m not supposed to be anywhere else or with anyone else. With this agency is where I belong. They’ve worked extremely hard and have been very professional in representing me. They are a major part of my success. #SIGFam”
