I want to get back into working out, is it wise to start slowly (perhaps, speed walking) before getting into the heavy cardio?

It’s been awhile since I’ve worked out and I really want to get back into it. Heavy cardio, at this point, is a no-go. I’m thinking that I’ll work my way up to that. What do you all suggest that I start with (besides the speed walking)? Do you think that this is the right way to go—the gradual build?
