Think in weeks, not perfect days
A useful beginner target is two strength-focused sessions a week. One can be a class or PT session. The other can be a short home workout or online coaching session.
If you miss one, you haven't failed. You just pick up the next sensible slot and keep going.
Add movement that doesn't feel like a workout
Walking, taking the stairs, pushing the pram, active play and short mobility breaks all help. They don't replace strength training, but they make your week more active.
NHS guidance suggests adults aim for regular activity across the week, including strengthening work for the major muscle groups.
Choose the support level you need
If you need confidence and technique, start with 1-to-1 PT. If you need a plan and accountability, online coaching can work well. If you want a friendly weekly anchor, the Tuesday band class is the simplest option.
The right plan isn't the most intense one. It's the one you'll actually return to.
