In the private sector, you are always auditioning. Joe Neal, owner of 2SP Sports Performance based near Detroit, MI, shares a blueprint for serving athletes from youth to the professional ranks. Those foundational principles support off-season training for National Hockey League (NHL) and Major League Baseball (MLB) players.

Along the way, his coaching was guided by self-experimentation, creative training techniques, and relentless learning. He explains what makes a strong private-sector program: coaches should be prepared, moving, and communicating, not buried in screens or programming. Neal also breaks down how he uses technology to individualize training, track progress, and support better decisions without losing supervision. He emphasizes long-term development, where overlooked athletes can keep growing, stay healthier, and outperform early expectations.
