A 3-day workout split for beginners

ACSM defines novice as untrained individuals with no resistance training experience or who have not trained for several years, intermediate as approximately 6 months of consistent training, and advanced as years of training (ACSM position stand, Progression Models in Resistance Training for Healthy Adults, Medicine & Science in Sports & Exercise, March 2009). The NSCA uses the same three levels and says the primary factor in setting training frequency is the client's training status and overall level of fitness, since lesser-trained clients usually require more rest between workouts (NSCA, Determination of Resistance Training Frequency, excerpted from NSCA's Essentials of Personal Training, 2nd edition).

If you have trained for less than about six months, or not at all for several years, every recommendation on this page for novices is the one that applies to you.

The federal floor is two. Adults should do muscle-strengthening activities of moderate or greater intensity that involve all major muscle groups on 2 or more days a week (HHS, Physical Activity Guidelines for Americans, 2nd edition, 2018). ACSM's recommendation is 2 to 3 days a week for novice training, 3 to 4 for intermediate, and 4 to 5 for advanced (ACSM, 2009). ACSM's 2026 update keeps the floor, with author Stuart Phillips saying that training all major muscle groups at least twice a week matters far more than chasing a perfect or complex plan (ACSM, announced March 17, 2026).

The NSCA spells out what a beginner's week looks like. The recommendation for the novice is to use frequencies of two or three days per week when training the entire body, on nonconsecutive days such as Monday and Thursday; Tuesday, Thursday, and Saturday; or Monday, Wednesday, and Friday (NSCA). For a client who reaches intermediate status, it recommends increasing to three or four days a week, which means training two or more days in a row, and names split routines, where a session trains only one part of the body, certain muscle areas, or push or pull movements, as a common strategy (NSCA).

So for a beginner, a 3-day split is a full-body session done three times a week with a day off between sessions.

A 2016 meta-analysis found higher training frequency associated with a greater hypertrophy effect size than lower frequency, 0.49 against 0.30, found that twice a week promoted superior hypertrophy to once a week on a volume-equated basis, and concluded that the major muscle groups should be trained at least twice a week to maximize growth. It left open whether three times a week beats twice (Schoenfeld, Ogborn and Krieger, Sports Medicine, November 2016).

A larger 2019 meta-analysis of 25 studies found no significant difference between higher and lower frequency when weekly volume was equated, and concluded that for a given volume people can choose a weekly frequency per muscle group based on personal preference (Schoenfeld, Grgic and Krieger, Journal of Sports Sciences, June 2019). For strength, a 2018 meta-analysis of 22 studies found effect sizes rising from 0.74 at once a week to 0.82, 0.93, and 1.08 at two, three, and four or more times a week, with no significant effect once volume was equated (Grgic et al., Sports Medicine, May 2018). Its authors read that as frequency mattering mainly as a way to fit in more volume, and note that most of the studies used untrained participants (Grgic 2018).

What that means for a three-day week is that the third day is extra room for sets. The second day is where the published gain against once a week sits.

ACSM recommends that novice loads correspond to a repetition range of an 8 to 12 repetition maximum (ACSM, 2009). The NIA says one set of eight to 12 repetitions of each exercise is effective, two or three sets may be more effective, and a beginner can try exercises without weights or bands until comfortable with the movements (NIA, content reviewed January 14, 2025).

On volume, a 2017 meta-analysis of 15 studies found a graded dose-response, with each additional weekly set associated with a 0.37% increase in muscle gain (Schoenfeld, Ogborn and Krieger, Journal of Sports Sciences, June 2017). ACSM's 2026 update gives about 10 sets per muscle group per week for hypertrophy and heavier loads of 80% of one-repetition maximum for 2 to 3 sets per exercise for strength (ACSM, 2026).

The NIA and ACSM's 2026 update disagree about effort, so each is printed with its owner. The NIA says to perform the exercises to the point at which it would be difficult to do another repetition (NIA, 2025). ACSM's 2026 update reports that training to fatigue or momentary muscle failure did not consistently impact outcomes for the average healthy adult (ACSM, 2026).

This week is built only from the rules above, with the owner of each rule on its line. It is a layout to fill with exercises from your plan, and it sets no loads.

• Days: Monday, Wednesday, Friday, each a full-body session, with at least one day off between (NSCA; NIA says avoid working the same muscle group on any two days in a row)
• Muscle groups each session: legs, hips, chest, back, abdomen, shoulders, and arms, which is the NIA's list of major muscle groups (NIA, 2025)
• Order within a session: large before small muscle groups, and multiple-joint before single-joint exercises (ACSM, 2009)
• Sets and repetitions: one set of 8 to 12 is effective and two or three may be more effective (NIA, 2025), at a load you can lift 8 to 12 times (ACSM, 2009)
• Warm-up: lighter weight on the same exercises first (HHS, 2018; NIA, 2025)
• Rest between sets: 1 to 2 minutes at the 6 to 12 repetition range (ACSM, 2009)
• Tuesday, Thursday, and the weekend: aerobic activity toward 150 minutes a week, or rest (HHS, 2018)
• Adding weight: 2 to 10% when you can do one or two repetitions over the target (ACSM, 2009)

One trial ran almost this exact shape. Resistance-trained men did 3 total-body workouts a week of 3 sets of 8 to 12 repetitions on 7 exercises for 8 weeks (Schoenfeld et al., Journal of Strength and Conditioning Research, July 2016). Those were experienced lifters, so their set count is higher than the NIA's starting point.

A warm-up for muscle-strengthening activity commonly involves doing exercises with lighter weight (HHS, 2018). The NIA says to warm up for muscle-strengthening activity by doing exercises with less weight, and for aerobic activity to do a little light activity, such as easy walking, before and after (NIA, 2025). The CDC's answer to a fear of injury is to learn how to warm up and cool down (CDC, Overcoming Barriers to Physical Activity, last reviewed February 5, 2025).

The injury evidence is thinner than the advice. A systematic review of five high-quality randomized trials found three where warming up significantly reduced injury risk and two where it did not, concluded there is insufficient evidence to endorse or discontinue routine warm-up, and said the weight of evidence favours a decreased risk (Fradkin, Gabbe and Cameron, Journal of Science and Medicine in Sport, June 2006).

ACSM gives rest by goal. For hypertrophy it gives 1 to 2 minutes between sets in the 6 to 12 repetition zone, and for heavy loads of 1 to 6 repetitions it gives 3 to 5 minutes (ACSM, 2009). A systematic review of six studies found that both short rests of 60 seconds or less and longer rests may be useful for hypertrophy, with newer findings in trained people suggesting a possible advantage for longer rests (Grgic et al., European Journal of Sport Science, September 2017). One trial in resistance-trained men found 3-minute rests produced greater strength and thigh muscle growth than 1-minute rests over 8 weeks (Schoenfeld et al., 2016).

Between sessions, the NSCA says novice clients should have 1 to 3 days between resistance training sessions, but never more than 3, to facilitate recovery (NSCA). The NIA says to avoid working the same muscle group on any two days in a row to allow for muscle recovery between sessions (NIA, 2025).

ACSM's progression rule is specific. When training at a given repetition-maximum load, apply a 2 to 10% increase in load once you can perform the current workload for one to two repetitions over the desired number (ACSM, 2009). The NIA names the other levers: gradual increases in the amount of weight, the number of sets or repetitions, or the number of days a week will result in stronger muscles (NIA, 2025).

The federal guidelines start slower for someone coming from nothing, saying muscle-strengthening can start at just 1 day a week at a light or moderate level of effort, build to 2 days, and then possibly more, with intensity increased slightly each week until it becomes moderate or greater (HHS, 2018). ACSM's 2026 update also reports that complex periodization did not consistently impact outcomes for the average healthy adult (ACSM, 2026).

You pick a three-day plan from the library, send me the one your trainer wrote, or we build one with the workout plan tool, and I text you that day's session on Monday, Wednesday, and Friday or whichever days you chose. You text back what you lifted in whatever shorthand you use, and I log every set. When you hit one or two repetitions over the target, I tell you the plan's rule says to add weight, which is ACSM's 2 to 10% (ACSM, 2009), and I keep the number you actually lifted. When a session slips, we move it so there is still a day between sessions and never more than three, which is the NSCA's spacing.

I never set your loads, never diagnose an ache, and never clear you for exercise. When what you tell me matches the symptoms in the line above, I say so and tell you to call.
