To achieve a targeted and defined muscle area (such as the abdominals or arms), it is sufficient to perform a specific exercise dedicated to that area.

The idea of targeting a muscle group to develop it is scientifically valid. A meta-analysis by Schoenfeld et al. (2017) confirms that localized resistance training effectively stimulates growth and strengthening in the worked muscle. However, if the message implies that these exercises allow for fat burning specifically in that area (the 'spot reduction' myth), science shows a different reality. A clinical study (RCT) by Ramirez-Campillo et al. (2013) demonstrated that training a specific limb does not lead to localized fat loss on that limb. The exercise presented is therefore excellent for sculpting muscle, but the final visual appearance depends on overall fat mass loss, which is strongly linked to nutrition.

What the graded evidence says

Evidence: A-

Effect: localized fat change in trained vs untrained/contralateral limb (spot reduction) — pooled Hedges' g = -0.03 (95% CI -0.10 to 0.05), 13 studies, n=1158: no spot reduction
Measured on: healthy adults, both sexes, ages 14-71

Targeted 'fat-burning' exercises for a specific area are a myth; the evidence consistently shows fat loss is systemic, not local.
