When William Kraemer first entered the field, strength and conditioning was, as he puts it, “primordial.” There were few standards, limited research, and little shared understanding. As one of the most influential figures in strength and conditioning, Kraemer recounts how the profession grew from humble beginnings into a science-driven discipline. That history still holds weight for coaches today. He explains why coaches are often drawn to new ideas, but progress comes from building on proven principles. Workout logs are central to his approach, and he notes how analyzing training over time can improve decision-making. He also emphasizes alignment across the performance ladder to support innovation and athlete development. As the Senior Advisor for Sports Performance and Sports Science at The Ohio State University, he shares his perspective on where the field is headed next. Apply his wisdom to stay grounded in solid principles, evaluate training with greater precision, and better serve your athletes.

Osteoporosis and low bone mineral density (BMD) are conditions that affect millions of people, and the amount of people afflicted is on the rise.
