New to again| home exercises

I had a baby back in 2023 September, i reached 209lbs (before i was like 110lbs. Anywho I lost most of that after the baby and sat at 160lbs and lost more weight. But I got all stressed and started over eating so I’m at 162lbs right now. My weight suggestion for my height is 95-124lbs (4’11). So right now I’m considered obese even though I don’t look it? But I feel the side effects, sluggish, out of breath, and random chest pains. I want to do something about it, I’ve been counting calories. But wonder about home exercises without equipment. Are they affective? How about Pilates? What do you guys suggest. What does your workout routine look like?

Also how do I get salmon to taste good?

Thank you.
