Exercise does more than shape muscles—it shapes your future health. Across Michigan, fitness professionals see every day how movement helps people feel stronger, sleep better, and think clearly.

Her clinical work focuses on how lifestyle behaviors—including exercise, nutrition, and stress management—affect long-term health. Sudnermann’s studies and public education efforts reinforce what health experts worldwide now agree on: consistent physical activity plays a central role in preventing and managing chronic disease.

Her research explores how exercise influences the body at every level. When people move regularly, their muscles release signaling proteins known as myokines that help reduce inflammation, regulate blood sugar, and strengthen immune defenses. Physical activity increases circulation and oxygen delivery to tissues, supporting their repair and regeneration. These physiological changes work together to maintain hormone balance, stabilize metabolism, and
