How to Start Working Out: A Simple 4-Week Plan

Updated 24 October 2026

Short answer

Start with two or three 30 to 45 minute sessions a week of simple full-body strength training, plus walking or other cardio on most days. Pick a plan, keep the effort moderate for the first few weeks, and build the habit before you build the intensity. The WHO recommends adults do muscle-strengthening activity on two or more days a week and 150 to 300 minutes of moderate aerobic activity.

Your first four weeks

Week	Strength	Cardio
1	2 sessions, 2 sets per exercise, easy	3 × 20-minute walks
2	2 sessions, 2–3 sets	3–4 × 25 minutes
3	3 sessions, 3 sets	4 × 30 minutes
4	3 sessions, add weight where reps are easy	150 minutes total, any mix

Before you start

If you have a heart condition, chest pain, dizziness, a recent injury, are pregnant or have been told to limit exercise, check with a doctor or an accredited exercise physiologist first. Exercise & Sports Science Australia publishes a free pre-exercise screening tool that helps you decide.

Making it stick

Schedule sessions like appointments: same days, same time.
Keep a simple log. Seeing numbers go up is motivating.
Expect some muscle soreness in the first week or two; it fades as you adapt.
Miss a session? Do the next one. Consistency over months beats any perfect week.

Frequently asked questions

Gym or home?

Either works. A gym gives more equipment and easier progression; home training with bodyweight, dumbbells or bands removes travel time. Pick the one you will actually do.

How long until I notice a difference?

Most people feel fitter and stronger within a few weeks. Visible changes take longer and depend a lot on food and sleep.
