How heavy of a weighted vest should I buy?

Across reviewers on r/walking and r/bodyweightfitness, the most repeated guidance is to start around 5–10% of bodyweight and progress from there. Walkers and beginners tend to land between 10–20 lbs; ruckers and strength-training users on r/Rucking commonly load 30–50+ lbs. Adjustable vests are repeatedly recommended over fixed-weight ones because users almost always want to scale up.
