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.

Surprising Findings
Training each muscle group daily (HFRT) did not produce greater strength or muscle gains than training each once weekly (LFRT), despite higher daily intensity and frequency.
Common fitness dogma claims frequent muscle stimulation (2–3x/week) is optimal for hypertrophy — this study shows even daily stimulation offers no advantage when volume is matched.
Practical Takeaways
If you're a trained lifter, you can choose between daily full-body workouts or a split routine — both work equally well as long as you hit 10–15 weekly sets per muscle group.

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.
