The short answer
Two, three or four days can all work. The useful choice is the one you can repeat while recovering well and managing the rest of your week. With two days, full-body sessions are practical. Three days also works well with full-body training or alternating emphasis. Four days can divide the work into shorter sessions, if that schedule feels easier to maintain.
Two days: a dependable starting point
Two full-body sessions on non-consecutive days are an efficient way to practice the main movement patterns. You could train Tuesday and Saturday, for example, and use walks or other enjoyable activity on the days between. This schedule leaves room for work, caregiving and recovery while giving you more than one opportunity to train each week.
Public-health guidance recommends muscle-strengthening activity for the major muscle groups on at least two days each week. That is a useful direction, not a demand to begin at a perfect dose. If you are new, shorter sessions and fewer exercises can help you establish the habit.
Three or four days: distribute the work
Three days can still use full-body sessions, or alternate two sessions so each one appears more than once across the week. Four days often works best when shorter workouts feel easier to fit in; it does not automatically mean better results. Leave enough time between demanding sessions for the same muscles to feel ready again.
Choose the schedule by looking at an ordinary week—not an unusually quiet one. A plan that survives school runs, travel and busy workdays is more useful than a demanding plan you repeatedly have to restart. If your energy or performance keeps dropping, reduce the workload and review sleep, food, stress and recovery.
A practical example
A two-day plan might use full-body sessions on Tuesday and Saturday. A three-day plan might use Monday, Wednesday and Friday, with a lighter day between sessions. Start with the version that fits your calendar now.

Look at the next two weeks and reserve the number of sessions you can realistically protect.
