Systematic Review
Con
Kordi R et al. · 2015Asian Journal of Sports MedicineSystematic review of studies examining localized fat loss through targeted exercise. Across all reviewed studies, no consistent evidence supported the concept of spot reduction. The reviewers concluded that subcutaneous fat is reduced in a generalized pattern determined by genetics and hormonal factors, not by which muscles are exercised.

Vispute SS et al. · 2011Journal of Strength and Conditioning ResearchSix-week RCT where participants performed 7 abdominal exercises (2 sets of 10 reps each) five days per week. There was no significant difference in abdominal subcutaneous fat, body fat percentage, waist circumference, or skinfold measurements between the exercise and control groups. Abdominal exercise alone did not reduce abdominal fat.

Ramírez-Campillo R et al. · 2013Journal of Strength and Conditioning Research12-week study where participants trained only one leg using leg press exercises. Fat loss occurred across the entire body, with the upper body and non-trained leg losing as much or more fat than the trained leg. This directly contradicts the concept of spot reduction and supports the systemic model of fat mobilization.
