Hypertrophy Training Guide

Overview

Training for size is less fussy than the internet suggests. A handful of variables matter, and the rest is preference.

Get volume, proximity to failure and progression right and you will grow. Get them wrong and no amount of exercise selection cleverness will rescue it.

Quick Answer

For muscle growth, train each muscle roughly 10 to 20 hard sets per week, split across two or more sessions, using rep ranges between 5 and 30 with most sets taken within one to three reps of failure, and add weight or reps over time.

Key Points

Weekly volume per muscle is the main dial.
Rep range matters much less than effort.
Two sessions per muscle per week beats one at the same volume.
Exercise selection matters most for the muscles you struggle to feel.
A block needs 8 to 12 weeks to show what it can do.

Rep ranges

Rep range	Best for	Cost
5 to 8	Growth plus strength, compound lifts	Higher joint and nervous system fatigue
8 to 15	The bread and butter of hypertrophy	Balanced
15 to 30	Isolation, joint-friendly work	Uncomfortable, high perceived effort

All three build muscle when sets are taken close to failure. Use the heavier ranges on compounds where you can load safely, and the higher ranges on isolation work where heavy loading is awkward.

How close to failure

Most working sets should end with one to three reps left in reserve.

Going to absolute failure on every set costs more recovery than it returns, particularly on compound lifts. Stopping five reps short does not produce enough stimulus. The useful window is narrower than beginners think and wider than perfectionists fear.

A practical rule: take the last set of each exercise closest to failure, and keep earlier sets one or two reps further away.

Structuring a week

Sessions per week	Structure	Sets per muscle per session
3	Full body	3 to 5
4	Upper lower	5 to 8
5 to 6	Push pull legs	4 to 7

Start each muscle at the lower end of 10 to 20 weekly sets and add a set or two every few weeks only if you are recovering well and progress has stalled.

Exercise selection

Two questions decide whether an exercise earns its place:

1. Can you load it progressively and safely?

2. Can you feel the target muscle working through the range?

A stretched position under load is worth prioritising. Romanian deadlifts for hamstrings, incline curls for biceps, overhead extensions for triceps and deep squats for quads all load the muscle where it is lengthened, which appears to be productive.

Muscle	One compound	One stretch-biased isolation
Chest	Bench press	Deep dumbbell fly
Back	Barbell row	Lat pulldown with a full stretch
Quads	Squat	Leg extension
Hamstrings	Romanian deadlift	Seated leg curl
Shoulders	Overhead press	Cable lateral raise
Triceps	Close grip bench	Overhead extension
Biceps	Chin up	Incline dumbbell curl

Running a block

Give a programme 8 to 12 weeks. Weeks 1 and 2 are for learning the lifts and setting starting weights. Weeks 3 to 10 are where progression happens. Take a deload when performance flattens across two consecutive weeks despite good sleep and food.

Change one thing at a time between blocks. Change everything and you learn nothing about what worked.

Common Mistakes

Mistake	Why it causes problems	Better approach
Adding exercises instead of load	Volume rises, stimulus does not	Progress the lifts you have
Only training in the 8 to 12 range	Misses the ends of the spectrum	Vary ranges across the week
Every set to absolute failure	Fatigue outpaces stimulus	1 to 3 reps in reserve on most sets
New programme every month	Nothing gets progressed	Commit to a block
Skipping legs	Half the body untrained	Two lower sessions a week minimum

Frequently Asked Questions

How many exercises per muscle group?

Two to four across a week is plenty for most muscles. More exercises is not more volume; four sets of one exercise and four sets across two exercises are both four sets.

Should I train to failure?

Selectively. Isolation exercises tolerate it well. Heavy compound lifts do not, because the fatigue cost is high and technique degrades.

Is machine work as good as free weights?

For hypertrophy, largely yes. Machines are often better for isolation because they remove balance as a limiting factor. Free weights transfer better to sport and general strength.

How long before I see changes?

Strength changes within weeks. Visible size changes usually take three to four months of consistent training, longer if you are already lean and trained.
