How do I start working out as a complete beginner?

Start with a plan you can actually repeat. For most people that means two or three full-body sessions a week, each built around five basic movement patterns: A squat, a hinge, a push, a pull, and a carry. Add some easy walking on the days in between and you have a complete beginner programme.

Why full-body training works at the start

When you are new, almost any reasonable stimulus produces change, and the limiting factor is skill rather than muscle size. Training the whole body two or three times a week means you practise each pattern often, which is how technique becomes automatic. It also means missing one session does not wipe out a whole muscle group for the week.

Much of your early progress comes from the nervous system learning to coordinate and recruit muscle more effectively rather than from the muscle itself getting bigger. That is covered in more depth in The Nervous System and Athletic Performance.

A sample first session

• Goblet squat — 3 sets of 8
• Romanian deadlift — 3 sets of 8
• Push-up, or an incline version — 3 sets of 6 to 10
• Seated cable row — 3 sets of 10
• Farmer's carry — 3 trips of 20 to 30 metres

Choose loads you can control for every planned rep. If the last rep of a set looks noticeably worse than the first, the weight is too heavy for now.

How to progress

Progression does not have to be dramatic. Adding one rep to a set, or a small increment of weight once the top of your rep range feels solid, is enough. Over three months those small additions compound into a large change. The underlying principle is explained in Principles of Strength Training.

What to expect in the first two months

Expect soreness after the first few sessions, rapid improvements in how the movements feel, and steady load increases. Visible changes take longer. Judge yourself on whether you completed the sessions you planned, not on the mirror.

Common mistakes

• Starting with six sessions a week and stopping after three weeks. Frequency you can sustain beats frequency that looks impressive.
• Changing the programme constantly. You cannot progress a lift you keep replacing.
• Chasing weight before the pattern is stable.
• Skipping warm-ups and then blaming the exercise for aches.

If you have an existing injury, a medical condition, or you are returning after a long layoff, get individual clearance and coaching before loading heavily.
