From your first ten minutes back after years off, to full-body routines you can keep going. Sustained, focused training.

WorkoutStart with a ten-minute walk and one set of five bodyweight squats, three days this week. That is the whole plan. The first month is not about getting fit, it is about proving to yourself that the sessions happen, because the people who fail at week six almost always started at week one with too much.
WorkoutThree full-body sessions a week, on non-consecutive days. Not a five-day body-part split. Full body hits every muscle two to three times a week, which the research favours, and it means a missed session costs you a fraction of a week rather than an entire muscle group.
WorkoutFive patterns per session: squat, hinge, push, pull, and a carry or core hold. Two to three sets each, eight to twelve repetitions, finishing every set with about two good reps left. Rest two to three minutes between hard sets. Same session all three days, and progress by adding a rep before you add weight.
