Daily vs Weekly Workouts: Which Builds More Muscle?
High-frequency resistance training is not more effective than low-frequency resistance training in increasing muscle mass and strength in well-trained men.

Two groups of strong guys trained for 8 weeks—one trained all muscles every day, the other trained each muscle just once a week. Both did the same total amount of work.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

If you're already experienced with weightlifting, doing full-body workouts every day gives you the same muscle and strength gains as doing different muscle groups on different days, as long as you do the same total amount of work each week.
If you're already strong and lift weights regularly, doing 10–15 hard sets per muscle group each week for 2 months will make you stronger and add a little muscle — whether you train your whole body every day or just once a week.
If you lift the same total amount of weight each week, it doesn’t matter if you spread it out over 5 days or do it all in 1–2 days — you’ll get the same strength and muscle gains.
High-frequency, low-volume daily training can induce significant strength gains in well-trained individuals without inducing overtraining.
