“A resistance-training program consisting only of front squats, Romanian deadlifts, incline bench press, and pull-ups can maintain overall muscle mass (hypertrophy) in healthy adults when performed with adequate training volume and progressive overload.”

A four-lift program like this can likely preserve a large share of muscle mass if effort, volume, and progression are sufficient, but the evidence does not show that it reliably maintains all major muscle groups on its own. The cited research supports compound training and progressive overload in general, not this exact exercise-only template. Muscles such as calves, lateral/rear delts, and some arm regions may need more direct work.

“The Romanian deadlift provides greater benefits for women compared to other exercises.”

No peer-reviewed evidence supports the claim that the Romanian deadlift provides greater benefits for women compared to other exercises. A systematic review and meta-analysis confirms that males and females adapt to resistance training with similar effect sizes, undermining any sex-specific superiority argument. Peer-reviewed studies show other exercises — including the barbell hip thrust and Roman chair back extension — match or exceed the RDL for the very muscles most often cited as reasons it benefits women. The claim relies entirely on non-scientific fitness publications.
