Fitness Fusion, a concept that involves blending different types of workouts, can break the monotony of a routine and challenge your body in new ways. This approach not only keeps the workout regimen exciting but also maximizes results by engaging different muscle groups and energy systems.

What is involved in Kelsey's PWR Fusion Program? There are three 30-45 minute strength training workouts each week to target and strengthen different muscle groups across your upper and lower body, plus an optional fourth core workout and weekly cardio sessions.
