Beginner template: 3 sets of 5 reps on each main lift, twice a week. That's it. Six work sets per session, done in under 45 minutes including warm-ups. Simple beats clever for the first six months.
Why 5 reps? It's the sweet spot for beginners. Heavy enough that technique matters (you'll practise good form under real load), light enough that you can do it twice a week without breaking down, and few enough that each rep is a chance to focus. Sets of 10 have their place, but not yet.
Warm-up before each lift: two or three sets with an empty bar and lighter weights, working up to your working set. Never jump straight to your top weight cold, a five-minute warm-up prevents most tweaks and injuries in this population.
Progression: add 5 lb to upper-body lifts (bench, overhead press) and 10 lb to lower-body lifts (squat, deadlift) every session you complete all sets with good form. This is called linear progression, and it works for six to nine months for most people. That's a full year of measurable strength gain every single week, most people never string together three weeks in a row of anything.
When you miss a rep, don't add weight next session, repeat the same weight. When you miss the same weight twice in a row, drop 10% and build back up. This is called a deload, and it's not failure, it's how you dig out of a plateau and often come back stronger than before.
Rest between sets: 3–5 minutes on the heavy stuff, no less. Short rest looks impressive on Instagram but wastes strength work. If you're not fully recovered, the next set trains cardio, not strength. Set a timer and use it.
Session structure: warm-up (5 min), main lift #1 with warm-up sets (15 min), main lift #2 with warm-up sets (15 min), optional accessory (10 min). Total: 45 minutes. If it's taking 90, you're either socialising or resting way too long.
Weekly template: Day A, squat, bench, row. Day B, deadlift, overhead press, row. At least one rest day between (Mon/Thu or Tue/Fri work well). Row can be a dumbbell row, barbell row, or seated cable row, pick one and progress it.
When to change the program: after linear progression truly stops working (three failed deloads in a row on the same lift), which for most people is 6–12 months in. Until then, resist the urge to switch. Novelty is fun; consistency is what builds strength.
