Ever feel like you’re working hard at the gym, but your results don’t quite reflect the effort? You’re not alone — and often, the missing link isn’t motivation, but structure. Enter the 4-day upper/lower split — a balanced, strength-building routine that targets your body in a logical, effective way.
Unlike random workouts that leave you guessing what to train next, this plan brings purpose to your gym time. It allows for focused effort on both upper and lower body, ensures ample recovery, and offers a scalable structure whether you’re lifting to get stronger, leaner, or simply more confident.
In this post, we’ll explore how the upper/lower split works, why it’s one of the most effective strategies for women seeking strength and definition, and how to put it into practice in a way that aligns with your schedule and goals.
Let’s ditch the guesswork — and build a plan that works with your body, not against it.
A 4-day upper/lower training plan divides your workouts by body region:
This format gives each muscle group two training sessions per week, with sufficient rest in between — one of the best frequencies for building strength and muscle efficiently.
This structure keeps your workouts focused and your progress steady. It also gives you Wednesday, Saturday, and Sunday for recovery or light movement, which is essential for muscle growth and overall recovery.
Let’s face it — many women prioritise leg and glute training, often leaving upper-body strength behind. But a strong upper body is more than just aesthetics. It supports better posture, reduces injury risk, and gives you more power in compound lifts.
An upper/lower split helps you:
Plus, training each region twice a week is optimal for progress — studies show it’s better than once-weekly splits for both strength and hypertrophy gains.
Doing full-body sessions too frequently can wear you down, especially if you’re pushing intensity. This split offers a smart balance — you work hard, then rest the trained muscles while hitting a different region.
And if you’re someone who’s navigating hormonal shifts, like perimenopause or menstrual phase fatigue, this kind of schedule lets you flex intensity and rest more naturally, as explained in our guide on how to adjust your plan menstrual cycle phases.
With fewer muscle groups per session, you can devote more energy and attention to each lift. This leads to:
Each workout should include a mix of:
Let’s break this down further.
On these days, your goal is to hit all the major muscle groups in the upper body. Here’s how a typical session might look:
You can rotate exercises weekly or stick with the same movements for 4–6 weeks to track progress clearly.
Lower body days are where you build the foundation — strength, stability, and definition. Here’s what a balanced session could look like:
Each session targets glutes, hamstrings, quads, and calves, while also challenging your core and cardiovascular system.
Looking to target your lower body further? You might enjoy exploring the best glute-building exercises with weights to complement this plan.
Don’t chase exhaustion or muscle burn alone. Aim to progressively overload by increasing weights, reps, or control over time.
Avoid back-to-back lower body sessions. Use rest days for light walking, stretching, or yoga to boost recovery.
Use a logbook or app to note your reps and weights each week. Tracking is one of the most effective tools for staying consistent and motivated.
It’s better to do 8 perfect reps with moderate weight than 15 sloppy ones with momentum. Your joints and muscles will thank you in the long run.

“I love this split. Four workouts a week are easy to stick to, and I’ve gotten noticeably stronger in my deadlifts and shoulder press. My clothes fit better, and I feel more confident walking into the gym knowing exactly what I’m doing.”
Maya, 44 – Yoga Instructor & Mum of Three:
“I used to think lifting was just for my legs. This routine helped me realise how powerful upper-body strength can be. Carrying groceries, kids, even doing handstands — everything has improved.”

It may not be ideal if:
Ultimately, the best programme is the one you can follow consistently and with intention.
The 4-day upper/lower training split is about more than just muscle — it’s about creating a stronger, more capable version of yourself. With the right structure, you’ll train smarter, progress faster, and feel more connected to your body’s abilities.
This routine gives you space to grow. It respects your recovery, challenges your strength, and builds a balanced physique without burning you out.
So grab your training log, map out your week, and commit to showing up. With four focused sessions, you’re building more than muscle — you’re building strength with purpose.
