I've lived a fairly sedentary lifestyle for quite a few years (aside from the small bits of neccessary walking), and I'm finding it hard to get from that towards being able to work out every day, which i'd really like to do.
I'm not weak, as I have quite a bit of muscle tone and weight lifting (in non-absurd amounts) is fairly easy for me, but I have a lot of trouble with things such as walking, cardio etc; the stamina things.

I've been trying to gradually scale up to improve my ability to do these things (with my end goal being going hiking for the first time in several years) but i'm finding it a very difficult, almost painful process.

Any advice on exercise methods or tips for breaking out of a sedentary body?

Walking is your best tool. Aim to add an extra minute every 3 days, and break it up into smaller walks. Start with a challenging, but doable, amount of time.

Eg. 8min walk in the morning, 8min walk in the evening x 3 days

9min walk in the morning, 9min walk in the evening x 3 days

In 2-3 months, you'll be walking for more than an hour a day! At that point, you should have more stamina to explore new options. But always keep up with your walking! 😊

Researchers have discovered that starting to reverse decades of sedentary living can require as little as four to five days of cardio exercise each week for two years. The study, which was published in the journal Circulation, examined the hearts of adults 45 to 64 years old who had never before engaged in regular exercise.
