Cory Gregory, a 45-year-old father and strength coach, created a four-week workout program targeting the "dad bod" physique that accumulates around the midsection and comes with reduced muscle mass. Gregory built the plan around compound movements and progressive overload, the training principle where you gradually increase weight or reps to force muscle adaptation.
The program combines resistance training with metabolic conditioning. Gregory emphasizes full-body workouts rather than isolated muscle splits, a strategy supported by research showing compound exercises recruit more muscle fibers and burn more calories than single-joint movements. The protocol incorporates movements like squats, deadlifts, and pressing variations that activate multiple muscle groups simultaneously.
The four-week timeline allows beginners to establish consistent training habits while creating enough stimulus for measurable body composition changes. Gregory's approach includes nutrition principles alongside training, recognizing that fat loss requires a caloric deficit. The program accounts for recovery, a factor often overlooked by older trainees whose bodies need more time between hard sessions.
Gregory's method aligns with how strength training combats sarcopenia, the age-related muscle loss that contributes to the dad bod appearance. As men age, testosterone declines and physical activity typically decreases, creating conditions for fat gain and muscle atrophy. Resistance training reverses both trends by stimulating muscle protein synthesis and improving insulin sensitivity.
The program targets functional strength that translates to daily life. A 45-year-old father needs the strength to move heavy loads and maintain energy through a busy day. Gregory's system builds that capacity while improving body composition.
THE BOTTOM LINE: A structured four-week resistance training program with progressive overload can reverse the body composition changes of middle age, provided you combine training with adequate nutrition and recovery.
