I kept trying and if I fell apart I would wait for a couple of weeks before trying again.

I was able to swim way before I could run again so I went with that. It was several months before I could get away with an extended elevated heart rate.

Your body will let you know when it's ready for the next level if you study it's signs without obsessing over them.

When I first started trying to reintroduce exercise to my day I could walk maybe 500' before exhaustion and I used 12 oz soup cans for weights. It was truly humiliating but I did manage to persevere as I was able.

It's all much better now, worth the struggle.
