I lost over 120 pounds with walking and stretching my only exercise.
I started during the pandemic, and have been able to keep the weight off with an hour of walking in the morning and an hour in the evening.
I average about 15k steps a day.
I did also adjust my portions - to sustain my over 300 pounds I was eating a lot more than I needed to. Currently eating about 2500 calories a day.
About a year ago I added a stretching routine before each walk, which has been very good and I have made progress in my flexibility.
Besides the exercise, just the time spent outdoors and soaking up nature has been a real benefit to my mental health.
I have only missed 2 days of walking since 2020, once after a surgery and once when I had a high fever and vertigo.
