The first 3 maybe 4 weeks are fair straight forward even though week 4 is definitely starting to crank it up week 5 onwards seem very daunting. Everyone has a different fitness level and mine was rock bottom to begin with. But here I am week 4 day one complete. The distance was almost on 4 k over the total workout today. Seeing the distance covered increasing steadily week by week. Feeling bloomin great though. Even if I've lost zero pounds since I started haha. Despite that I do feel tons better and care not what the scales say.
