The upper/lower split is the standard next step once a beginner’s full body routine stops producing new gains, and it’s the most common structure serious intermediate lifters use for muscle gain. Instead of training your whole body in one session, you split the week into two upper body days and two lower body days, which frees up enough session time to add real per-muscle-group volume without any single workout running past an hour.
This plan uses an A/B rotation for both upper and lower days so that each muscle group is trained through two slightly different rep ranges and exercise variations across the week. Day 1 (Upper A) and Day 3 (Upper B) both hit chest, back, shoulders, and arms, but Day 1 leans into heavier 6 to 8 rep work on the main lifts while Day 3 shifts to higher rep, higher fatigue work and adds pull-ups as the primary vertical pulling movement. The same pattern repeats for lower body: Day 2 emphasizes the squat as the heavy compound lift, while Day 4 puts the deadlift first when you’re freshest for that movement, then follows with lighter squat work.
Progressive overload here works on a two-week rotation rather than session to session, since each lift only appears at its heaviest rep range once a week. Track your top set weight for the main lift on each day (bench press on Day 1, squat on Day 2, overhead press on Day 3, deadlift on Day 4) and aim to add weight or a rep every one to two weeks. Because upper/lower splits ask for higher total volume per session than full body training, expect more accumulated fatigue; if a lift stalls for two consecutive weeks, hold the weight steady rather than pushing through, and make sure your total calorie intake supports muscle building, since a genuine calorie surplus matters more here than any single set or rep adjustment.
A Monday, Tuesday, Thursday, Friday schedule (Upper, Lower, Upper, Lower with Wednesday off) works well and gives each muscle group roughly 72 hours of recovery before its next session. Some lifters prefer Monday, Tuesday off, Wednesday, Thursday off, Friday off, weekend free; either works as long as you don’t train the same body part twice within 48 hours.
Sleep and protein intake become more important at this stage than they were as a beginner, since the added training volume creates more total recovery demand. Aim for roughly 0.8 to 1 gram of protein per pound of bodyweight and 7 to 9 hours of sleep. If you eventually find that four sessions a week isn’t producing new muscle gains despite consistent progressive overload and adequate recovery, a 5 or 6 day push/pull/legs split is the typical next step, since it allows even more per-muscle-group volume by further narrowing what each session trains.

How to Progress This Plan
- Weeks 1-2: learn the movements: Use a weight where the last 1-2 reps of each set feel hard but controlled. Focus on consistent form across all 4 sessions per week before chasing heavier loads.
- Weeks 3-4: add load or reps: Once every set in a session hits the top of its rep range with good form, add weight (or reps for bodyweight movements) the next time you train that session.
- Ongoing: track and adjust: Log your sets and reps every session. If a lift stalls for two sessions in a row, hold the load steady for one more week before pushing again.
- If you miss a session: Don't try to make it up by doubling a workout. Pick the plan back up at the next scheduled day; consistency over weeks matters more than any single missed session.

Frequently Asked Questions
- Why is upper/lower better than full body for muscle gain?
- At the intermediate stage, an upper/lower split lets you fit more total sets per muscle group into each session without the workout running too long, since you're only training half your body per day instead of all of it. That extra per-session volume is what drives continued muscle growth once full body sessions stop producing new gains.
- How much weekly volume does this plan provide per muscle group?
- Most muscle groups get 12 to 16 hard sets per week across the two upper or two lower sessions, which sits in the range shown to maximize hypertrophy for intermediate lifters without exceeding recoverable volume.
- Can I do this plan with only dumbbells?
- Yes, with adjustments; see the 4 day dumbbell only muscle gain plan for the equivalent structure built specifically around dumbbells instead of barbells and machines.
