3-day workout split for women: a full plan

Three days a week is the sweet spot for most people who lift. It's enough to train every muscle twice or more, few enough to survive a busy month, and it leaves room for running. This 3 day workout split for women gives you two complete layouts, the weekly set math behind them, a 12-week progression, and sample weeks with runs already slotted in.

If you'd rather not schedule it yourself, an AI coach for running and lifting will build and adjust it each week. If you would, here's everything.

Which 3-day split should you run?

There are two good options, and one popular one that's worse than it looks.

Our default is full body A/B/C. It's the backbone of a lifting plan for women built around running, and the same routine sits at the center of the women's gym workout guide. If you're brand new, start one step earlier with the beginner fitness program for women, which builds up to three days over eight weeks.

Nothing here is a women-only design. The principles that work for anyone work for women, and the same training produces similar relative gains in muscle size and lower-body strength between sexes (Roberts et al., 2020). The pillar guide on the best strength training apps for women covers the research behind that.

Why the split matters less than the sets

A 2024 meta-analysis found split routines and full-body routines produced similar strength gains and muscle growth when weekly volume was matched, and concluded people can choose based on preference (Ramos-Campo et al., 2024). A frequency meta-analysis found the same for muscle growth: with volume equal, training a muscle one, two or three-plus times a week made no meaningful difference (Schoenfeld et al., 2019).

So pick the layout you'll complete. For the bigger comparison of full body, upper/lower and push pull legs, workout splits explained has sample weeks for each.

Option 1: the full-body 3 day split women's workout

Train on three non-consecutive days, such as Monday, Wednesday and Friday. Each day hits the whole body, but the heavy lower-body lift rotates so you're never squatting heavy three times a week.

Day A: squat focus

Day B: hinge focus

Day C: single-leg and volume

RPE 8 means about two reps left in the tank. Pick weights that let you hit the bottom of the rep range at that effort, then build reps from there.

Option 2: lower / upper / full

If you prefer longer, more focused sessions, or you want a dedicated leg day, this layout works well. It puts most of the leg fatigue on one day, which some runners like.

The catch: legs get one big day and one moderate day, upper body gets one big day and one moderate day. That's fine for most goals. Full body A/B/C spreads things more evenly and survives missed sessions better.

Sets per muscle: does this add up?

Counting direct hard sets, the full-body version gives roughly:

That sits in a sensible range for beginners and early intermediates, who generally do well on 6 to 10 weekly hard sets per muscle. As you progress, add a set to the lifts for the muscles you care most about rather than adding new exercises. For what to add for each body part, workouts for women explained lists the exercises that matter.

How to progress a 3 day split workout for women

Use double progression on every lift:

1. ›Start each lift at a weight you can do for the bottom of its rep range at about RPE 7–8.
2. ›Add reps each session, until you hit the top of the range on every set.
3. ›Add a small amount of weight and drop back to the bottom.

Take a lighter week every four to six weeks: same lifts, fewer sets, a bit less weight. A 12-week block looks like this:

After 12 weeks, keep going if you're still progressing. If you have the time and recovery for a fourth day, the natural next step is a 4 day workout split for women, usually as an upper/lower layout.

Where your runs go

Running and lifting fit together if you schedule them sensibly. A 2022 meta-analysis found adding aerobic training to strength training didn't compromise maximal strength or muscle growth, though explosive strength gains were lower, especially when both were done in the same session (Schumann et al., 2022).

The rules: no heavy legs the day before a hard run or your long run; when a hard run and a lift share a day, run first and leave a few hours between them; and let easy runs fill the gaps.

Full body A/B/C + 3 runs

Day C lands the day before the long run, so keep its leg work moderate: stop the split squats and leg curls with two or three reps in the tank. If your long run is a key session, move Day C to Thursday.

Lower / upper / full + 3 runs

Upper-body days pair happily with hard runs. Heavy leg days get space. Zoom out to a month and you have a women's weight lifting schedule, explained in one line: these weeks, repeated, with a lighter one every four to six weeks.

Common mistakes with a women's 3 day split workout

Turning it into three leg days. Glutes and legs are a fine priority, but a plan with no pulling and pressing is a plan with gaps. Keep the rows and presses.

Too many exercises. Five exercises per session, done hard, beats nine done half-heartedly.

Changing the plan every two weeks. Progress comes from adding weight or reps to the same lifts. Run the split for at least one 12-week block before judging it.

Chasing soreness. Soreness isn't a measure of a good session. The logbook is.

Ignoring the running. If you run three times a week, your legs are already busy. Keep leg volume moderate and the hard sessions apart.

Full body or upper/lower at three days?

At three days, full body is the default for most people because each muscle gets trained three times and a missed session doesn't erase a muscle group for the week. Lower/upper/full is a good alternative if you like focused sessions. The longer comparison lives in our guide to upper/lower vs full body, but the short answer is: either works, so choose the one you'll show up for.

How exrsz handles a 3-day split

exrsz builds your three lifting days and your running into one periodized plan, based on your goal, schedule, level and equipment. It keeps heavy leg days away from hard runs, adapts each week to how you actually trained, and reshuffles missed sessions instead of stacking them onto the next day.

FAQ

Is a 3 day workout split good for women?

Yes. Three full-body sessions a week train every muscle several times, leave room for recovery and running, and match the research showing split and full-body routines produce similar results when volume is matched (Ramos-Campo et al., 2024).

What is the best 3 day split for women?

For most women, full body A/B/C with a rotating lower-body focus. Lower/upper/full is a good alternative if you prefer more focused sessions.

How many exercises should a 3 day split workout have?

Four to six per session is plenty: one main lift, two or three secondary lifts, and one or two accessories.

Can I run on a 3 day split?

Yes. Avoid heavy legs the day before a hard run or your long run, put a hard run and a lift on the same day (run first) when they have to share, and let easy runs fill the gaps.

How long should I follow a 3 day workout split for women?

Run it for at least one 12-week block, with a lighter week every four to six weeks. Keep going as long as your lifts are still improving.
