Designing a Gym Routine

A training split is how you divide your weekly training across muscle groups and sessions. The major options vary in training frequency per muscle group, total weekly volume, and required time commitment.

Split Type	Sessions/Week	Frequency per Muscle	Best For	Key Limitation
Full-body	2–4	2–4× per week	Beginners, time-limited, strength focus	Limited exercise variety; session length
Upper/Lower	4	2× per week	Intermediate lifters, 4-day schedules	Less specialisation per session
Push/Pull/Legs (PPL)	3 (once) or 6 (twice)	1× (3-day) or 2× (6-day)	Intermediate–Advanced, 5–6 day schedules	3-day PPL has low frequency per muscle
Bro split (1 muscle/day)	5–6	1× per week	Bodybuilding isolation focus (advanced)	Very low frequency; suboptimal for most
Conjugate / concurrent	4	Mixed	Powerlifting, athletic development	Complex programming; requires experience

Research consistently shows that training a muscle twice per week produces superior hypertrophy outcomes compared to once per week at the same total volume. The bro split (one muscle group per day) is popular but not well-supported by the evidence for general muscle building — the total weekly frequency per muscle is too low.

Tip: When choosing a split, be honest about how many days you can realistically commit to, including travel, illness, and family obligations. An intermediate split done 80% consistently beats an advanced split done 50% consistently.

The Push/Pull/Legs (PPL) split divides training into three workout types: Push days (chest, shoulders, triceps), Pull days (back, biceps, rear deltoids), and Leg days (quadriceps, hamstrings, glutes, calves). Each session trains muscle groups that work together synergistically.

Day	Muscle Groups	Primary Exercises	Isolation Exercises
Push	Chest, anterior/lateral deltoid, triceps	Bench press, overhead press, incline press	Lateral raise, cable fly, tricep pushdown
Pull	Lats, rhomboids, biceps, rear deltoid, traps	Deadlift / weighted pull-up, barbell row	Face pull, bicep curl, rear fly
Legs	Quads, hamstrings, glutes, calves	Squat, Romanian deadlift, leg press	Leg curl, calf raise, leg extension

3-day PPL (Mon/Wed/Fri): Each muscle group trained once per week. Suitable as an introduction to the split, but muscle frequency is suboptimal for hypertrophy.

6-day PPL (Mon–Sat, Push/Pull/Legs/Push/Pull/Legs): Each muscle group trained twice per week. Optimal frequency, but requires 6 training days — unrealistic for many people.

5-day PPL (Push/Pull/Legs/Push/Pull, then repeat): A practical compromise where muscles are hit 1.5–2× per week on average. Works well for those who can manage 5 gym days per week consistently.

The Upper/Lower split trains the upper body (chest, back, shoulders, arms) on two days and the lower body (quads, hamstrings, glutes, calves) on two days, in a 4-day-per-week schedule. Each muscle group is trained twice per week, providing the optimal frequency for hypertrophy without requiring more than 4 sessions.

This split is widely considered the best balance of frequency, volume, and time for intermediate lifters who can train 4 days per week.

Day	Focus	Exercise Selection	Rep Range
Upper A (Monday)	Strength emphasis	Bench press 4×5, barbell row 4×5, OHP 3×6, pull-up 3×6	3–6 reps (strength)
Lower A (Tuesday)	Strength emphasis	Squat 4×5, Romanian deadlift 3×6, leg press 3×8	3–8 reps
Rest (Wednesday)	Active recovery or rest	Walk, mobility work, yoga	—
Upper B (Thursday)	Hypertrophy emphasis	Incline DB press 3×10, cable row 3×10, lateral raise 4×15, curl 3×12	8–15 reps
Lower B (Friday)	Hypertrophy emphasis	Front squat or hack squat 3×10, leg curl 3×12, Bulgarian split squat 3×10, calf raise 4×15	8–15 reps

The alternating strength and hypertrophy emphasis within each muscle group ensures both neural adaptations (from lower-rep, heavier work) and volumetric hypertrophy (from higher-rep work) are developed simultaneously.

Full-body training works every major muscle group in each session, typically 3 days per week. Despite its simplicity, it is among the most effective approaches for beginners and intermediate lifters and produces excellent results even for advanced athletes during conditioning or maintenance phases.

The primary advantage is frequency: each muscle group is trained 3× per week rather than 1–2×. Research suggests 3× per week may be optimal for hypertrophy given adequate recovery between sessions.

Slot	Exercise	Sets × Reps	Pattern
1	Squat variation (squat / front squat / goblet squat)	3–4 × 5–8	Knee-dominant push
2	Hinge (deadlift / RDL / trap bar deadlift)	3 × 5–8	Hip-dominant hinge
3	Horizontal push (bench press / dumbbell press)	3 × 6–10	Push
4	Horizontal pull (row variation)	3 × 6–10	Pull
5	Vertical push or pull (OHP / pull-up)	3 × 6–10	Push or pull
6	Isolation (optional: 1–2 exercises)	2–3 × 10–15	Target weak links

Rotate the primary exercise selection across days (e.g., back squat Monday, front squat Wednesday, goblet squat Friday) to vary stimulus while training the same pattern. Session length: 50–70 minutes.

Tip: Full-body training requires that each individual session not completely exhaust a muscle group — leave 2–3 reps in reserve on all sets to ensure the muscle can be trained again 48 hours later. Going to complete failure on full-body training extends recovery time and breaks the 3×/week frequency.

The theoretically optimal split is useless if your schedule doesn't support it. The table below maps available training days to the best-fit splits and expected outcomes.

Training Days/Week	Best Split Options	Muscle Frequency	Expected Outcome
2 days	Full-body 2×	2× per week	Good for maintenance; modest gains possible
3 days	Full-body 3×	3× per week	Excellent for beginners and intermediates; strong gains
4 days	Upper/Lower (2+2)	2× per week	Optimal for most intermediate lifters
4 days	Full-body 2× + PPL Upper/Lower hybrid	2–3× per week	High flexibility; good for varied schedules
5 days	PPL + 2 extra (Upper/Lower or Full-body)	2× per week	High volume; intermediate–advanced
6 days	6-day PPL or Upper/Lower/Full/Upper/Lower/Full	2× per week	Maximum volume; advanced athletes

When schedule flexibility varies week to week, full-body training is the most resilient split — missing one session of a full-body programme has less impact than missing one session of a PPL programme where an entire muscle group goes unworked for 2 weeks.

Warning: More training days is not always better. Every additional session adds recovery demand. Unless sleep, nutrition, and stress are all well-managed, adding sessions beyond 4–5/week often produces diminishing returns or regression due to accumulated fatigue.
