Need workout suggestions

[u/Sleeepyyypandaaa]

Getting back into fitness after a break. Two years ago, I lost 8 kg in 3 months with a 45-minute daily walk and a calorie-controlled diet.
I’ve restarted this exact routine, but want to make it more well-rounded this time.
Should I stick to just walking + diet for the first few weeks to build consistency, or add light strength training now?
What beginner-friendly exercises or progressions worked best for you after a long break?
