What does the research say about training frequency?
The 2018 meta-analysis covered 12 studies and 74 treatment groups. Without matching volume, the effect sizes rose with frequency: 0.74, 0.82, 0.93 and 1.08 for training one, two, three and four or more times per week. When volume was equated, the difference between lower and higher frequency was close to zero (effect size 0.03, not significant). The authors concluded that the existing data does not show a strong link between higher weekly frequency and strength gain.
In plain terms, more days tend to go with more sets, and the extra sets seem to explain most of the difference.
How many days should beginners train?
The ACSM position stand from 2009 suggests that novices train the whole body about two to three days per week. That gives each muscle several hits a week with time to recover between sessions.
What about intermediate and advanced lifters?
The same stand suggests more days as experience grows, up to four or five days for advanced lifters. At those levels, splitting the week into upper and lower or push, pull and legs mostly lets you fit more sets without making each session too long.
Does it matter how you spread your sets?
If your total weekly sets are the same, the research suggests strength results will be similar whether you spread them over fewer or more days. Choose the schedule you can keep up for months.
How should you schedule your days?
- Avoid training the same muscles hard on consecutive days.
- Leave a rest day between full-body sessions.
- Pick days that fit your week, and keep them as stable as you can.
Roarer lets you build or edit a plan, schedule your training days with optional reminders, and log every set, so you can see how many sessions and sets you really do each week.
