Summary

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.

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.
