The Tried-And-Tested Muscle-Building Workout
Pack on upper-body size with this intense but rewarding torso-transforming 28-day plan
Want to make a big change to the way you look with your shirt off? Then you need to make a big effort in the gym – but there’s no point throwing weights around if you’re not training smart. That’s where this four-week training block comes in. It’ll transform your torso in double-quick time by hitting your major upper muscle groups multiple times each week to shock your body into rebuilding the damaged muscle fibres bigger and stronger. The result? In just 28 days, you will have packed on serious size across your upper body – and will be stronger and leaner to boot.
How the plan works
In each of the four weeks of this 28-day plan, you will train your major upper-body muscles twice to stimulate a response that will build them back bigger and stronger.
Don’t worry if working your chest, back, shoulders, biceps and triceps more than once a week sounds like a lot. Firstly, it is a lot, and that’s what it takes to make big changes to your physique fast.
Secondly, you won’t hit these muscles in the same way in consecutive sessions: the workout plan has been carefully designed so these muscles get a fresh stimulus to keep the gains coming without the risk of injury, fatigue or overtraining. The first session of each week hits your chest and back, the second one your biceps and triceps, the third your legs and back, and the fourth your shoulders and chest.
All four weekly workouts have five moves, which you’ll perform as straight sets, so simply work through moves 1 to 5. Do the workouts in order, sticking to the exercises, sets, reps, tempo and rest periods detailed. Try to leave a day between sessions where possible, and ensure you’re consuming lots of protein and getting enough sleep.
Tempo training
To get the full effect from these workouts, you need to stick to the four-digit tempo code for each exercise. The first digit indicates how long in seconds you take to lower the weight, the second how long you pause at the bottom of the move, the third how long you take to lift the weight, and the final digit how long you pause at the top. X means that part of the move should be done explosively. The accumulated time under tension increases your heart rate to burn fat and break down muscle tissue so it’s rebuilt bigger and stronger. Keep each rep smooth and controlled so your muscles – not momentum – do the work.
How to warm up
This workout places a significant amount of stress on your muscles by asking them to work overtime, so as the training plan progresses fatigue will build up. That makes it even more important than usual that you don’t go into your workout cold, because you’re likely to struggle to maintain good form and this can increase your risk of injury.

As the plan below also involves training each part of your upper body twice a week, the chances are you’ll have some residual muscle soreness in the area you’re about to target with your workout. That’s another reason to spend five to ten minutes warming up those muscles so you’re not tight and creaky when you go into your reps proper.
By warming up, we don’t mean five half-hearted minutes on the treadmill or exercise bike. You need to prepare for the movements you’re actually about to do. This warm-up routine starts with seven dynamic stretches that loosen up the body generally, but then moves on to an exercise-specific section. In each of the workouts below you’ll do five different exercises, so it’s worth running through each of them in turn using a light weight, or no weight at all if appropriate – press-ups are a good warm-up for the bench press, for example.
Skipping this part might seem appealing, but you’ll reap instant dividends when you hit your first set hard rather than starting on the back foot.
