Adherence
Supervised resistance training produces greater site-specific muscle hypertrophy and strength gains compared to unsupervised training in resistance-trained individuals.
If you are already experienced with resistance training, working with a coach or trainer who provides real-time feedback and encouragement will likely lead to better muscle growth and strength gains than training alone. The supervision helps you push closer to failure with better technique, which drives adaptation.
Results showed the SUP group achieved superior increases in muscle thickness for the triceps brachii, all sites of the rectus femoris, and the proximal region of the vastus lateralis. Squat 1RM was greater for SUP; bench press 1RM was similar between conditions.
Why this rating
Randomized controlled trial with pre-registration, blinding of outcome assessors, and site-specific ultrasound measurements, though limited to young, recreationally trained individuals.
