Michael “Dr. Mike” Israetel was born on May 30, 1984, in Moscow, then part of the Soviet Union. His parents are Alexander and Yelena Israetel, and he was born into a Jewish family. In 1991, at age seven, he emigrated with his family from Russia to the United States. They settled in the Detroit, Michigan area, where Israetel grew up in Metro Detroit.
Raised in a Jewish household, Israetel attended local Jewish schools, including a Jewish Community Center school in Oak Park and later Hillel Day School in the Farmington Hills area of Michigan. During high school in Detroit, he began weight training to improve his wrestling performance. His interest in strength training began during adolescence and became a lifelong focus.
Israetel later enrolled at the University of Michigan, Ann Arbor, for his undergraduate studies. He earned a Master’s degree in Exercise Science from Appalachian State University in North Carolina and later completed a Ph.D. in Sport Physiology at East Tennessee State University in Johnson City, Tennessee. He completed these academic qualifications in exercise and sports science before beginning his later professional career in fitness and strength training.

Dr. Michael “Mike” Israetel, PhD, is a sport physiologist and co-founder of Renaissance Periodization (RP Strength), where he serves as Chief Content Officer. He holds a doctorate in Sport Physiology from East Tennessee State University and has extensive experience applying exercise science in practice. His career has combined academic work, coaching, and consulting, with a focus on helping athletes and recreational lifters optimize their training and nutrition through evidence-based methods.
Sport Physiology Research and Academic Teaching
After earning his PhD in Sport Physiology, Dr. Israetel pursued an academic career in exercise science. He has been a professor of Exercise and Sport Science at Lehman College and Temple University and has also taught at the University of Central Missouri. In these faculty roles, he developed and taught courses on strength training, hypertrophy (muscle growth), and sports nutrition for future coaches and sports scientists.
Earlier in his career, Dr. Israetel worked as a sports nutrition consultant at the U.S. Olympic Training Site in Johnson City, Tennessee, applying scientific nutrition strategies with competitive athletes. He has also been an invited speaker at many scientific and performance conferences, including seminars at the U.S. Olympic Training Center in Lake Placid, where he shared research insights on training and nutrition. During this period, he also coached athletes on optimized training and diet strategies while connecting laboratory research with practical coaching.
Cofounding Renaissance Periodization
In the late 2000s, Dr. Israetel co-founded Renaissance Periodization, also known as RP Strength, with Nick Shaw. Their aim was to turn rigorous exercise science into practical coaching tools. The business grew from a small coaching operation into a multi-million-dollar fitness company known for its science-backed training and nutrition systems.
As co-founder, Dr. Israetel helped establish RP’s philosophy that training and diet should be driven by research. Under his leadership, the company developed programs and products used by athletes worldwide. He also co-hosts the RP Strength podcast with CEO Nick Shaw, discussing the application of scientific principles to strength, bodybuilding, and diet. Together, the co-founders have grown RP Strength into a respected brand among strength coaches and serious lifters.
Building RP Strength’s Evidence-Based Training Systems
Drawing on his academic background, Dr. Israetel led the creation of RP’s flagship training platforms. He is the head designer of the RP Hypertrophy App and the RP Diet Coach App, two adaptive coaching tools built around evidence-based protocols. The Hypertrophy App structures each user’s progressive overload, training volume, and fatigue management according to established muscle-growth science, while the Diet Coach App applies validated nutrition science to individual goals.
Dr. Israetel oversaw the development of these programs to keep them aligned with peer-reviewed research on muscle growth, strength gains, and the effects of nutrition on performance. The programs turn complex exercise science into practical, automated plans designed to help athletes train more effectively rather than rely on guesswork.
