A good chest and shoulder workout needs exercises you can control, enough effort to challenge your muscles and a plan you can repeat. Mixing rep ranges is one way to put that together. It does not require maximum weights or a race from one exercise to the next.
The routine below uses the original 5–20 idea: five overhead presses, ten dips, fifteen push-ups and twenty triceps extensions. It is an adaptable workout template, not a specially proven muscle-building method.
Do heavy weights or high reps build more muscle?
Both can contribute to muscle growth. A systematic review comparing lower and higher loads found that muscle growth could occur across different loading ranges, while heavier loads generally produced larger improvements in maximum strength. Many of the included protocols involved sets taken to muscular failure; that does not mean every set in your own workout needs to reach failure. Read the review.
Choose a weight or exercise variation that makes the final repetitions challenging without forcing you to change your technique. Aim to finish with roughly two good repetitions still possible.
How to run the workout
This version uses straight sets. Finish your sets of one exercise before moving to the next. That gives you more time to recover before repeating a demanding movement.
| Exercise | Starting sets | Reps per set | Suggested rest |
|---|---|---|---|
| Standing overhead press | 2 | 5 | 2–3 minutes |
| Assisted or bodyweight dips | 2 | 10 | 2 minutes |
| Push-ups | 2 | 15 | 1–2 minutes |
| Cable triceps extensions | 2 | 20 | 1–2 minutes |
These numbers are starting targets. Rest longer when needed, or reduce the repetitions if your form deteriorates. If you are new to lifting, begin with lighter presses for 8–12 controlled repetitions instead of aiming for a heavy five-rep set. Take the rest of your weekly pressing volume into account before adding sets.
Warm up first
Start with a few minutes of easy movement, then practise your presses with an empty bar or light dumbbells. Build up gradually with lighter preparation sets. The warm-up should leave you ready to train rather than tired.
1. Standing overhead press
Stand with your feet comfortably apart and hold the bar at upper-chest height. Brace your trunk and press upward while keeping the bar close to your body. Avoid leaning back to complete the lift. Lower the bar under control.
Use a comfortable grip and a load you can handle without momentum. A seated dumbbell press is an alternative if you prefer it. For more technique detail, see our overhead press guide.
2. Dips
Use purpose-built parallel bars or an assisted dip machine. Start from a stable support position, then lower slowly through a comfortable range before pressing back up. You do not need to force a deep stretch.
If ten controlled repetitions are too demanding, use assistance. If dips cause shoulder discomfort, substitute a machine chest press or incline push-up. Avoid makeshift supports such as chair backs.
3. Push-ups
Place your hands around shoulder width and keep your head, trunk and hips in line. Lower your chest with control, letting your elbows travel at a comfortable angle rather than flaring straight outward. Press back to the starting position.
Raise your hands onto a stable bench if fifteen repetitions are too difficult. Stop the set before your hips sag or you lose control of the lowering phase.
4. Cable triceps extensions
Stand at a cable station with a rope or suitable handle. Keep your upper arms near your sides, extend your elbows and return slowly. Choose a light enough load to complete the repetitions without swinging your shoulders or torso.
This replaces the original heavy-bar-over-the-forehead variation and is easier to adjust as fatigue builds.
Make progress you can measure
Record the weight, repetitions and how the sets felt. When every set is controlled and comfortably within reach, make one small change: add a little weight, reduce assistance or choose a harder push-up variation. Keep the other variables steady so you can judge the difference.
Allow recovery before your next hard pressing session and balance this workout with pulling and lower-body exercises elsewhere in the week. Stop any movement that causes sharp pain. Consistent, repeatable training matters more than making one session exhausting.
